Add install rules for Abseil CMake.
These are attempted to be limited to in-project installation. This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time. Second, the presence of an install rule makes life massively simpler for package manager maintainers.
Currently this doesn't install absl tests or testonly libraries. This can be added in a follow-up patch.
Fixes #38, Fixes #80, Closes #182

Add SFINAE to absl::optional::optional(in_place_t, Args...)
This constructor previously didn't have SFINAE because the SFINAE
acted badly when Clang was trying to figure out what special
members to declare. Specifically, while considering copy
constructors it would attempt to call `optional(in_place_t) [ with Args = <>
]`, which evaluated `is_constructible<T>`, which shouldn't have been
evaluated.
This patch avoids the eager SFINAE bug by deducing the in_place_t tag
and short-circuting the SFINAE if the argument passed is not exactly
in_place_t.
I fixed the same bug in libc++ in the same way.

Remove absl_internal_blah names form CMake. We are always creating the alias target now, since use of these targets still requires including a header with internal in the name. This simplifies target naming a bit, especially for installation where we have to generate non-prefixed target names to export in the absl:: namespace.

Make the `long double` overload if AbslHashValue a template to avoid invalid
conversions with implicit operators.
This overload was never meant to capture anything other than `long double` and any current caller to it that wasn't a `long double` is potentially a bug.
In particular, any type with an implicit `bool` conversion is calling this
overload instead of trying to find a hash<> specialization, thus causing
pretty bad hash behavior.

Don't enable ABSL_HAVE_STD_IS_TRIVIALLY_ASSIGNABLE with MSVC when used with nvcc.
With nvcc on Windows __has_trivial_assign(int) is false; that leads to a failure of the check in is_trivially_copy_assignable. A better solution would probably be to use the std-provided check in this case, but that seems like a more intrusive change.

Cleanup std::hash probing metafunctions.
Previously there were two different ways to probe for
std::hash. One in hash.h and another in type_traits.h,
and they were both implemented differently, and neither
correctly worked around bad STL implementations.
This patch unifies the implementations into a single IsHashable trait.
It also:
* Correctly checks for old libc++ versions where this won't work.
* Avoids undefined behavior which resulted from calling std::is_constructible
incomplete types.
* Unifies the feature test macro used in the headers and the tests.
Additionally it also slightly changes the behavior of when absl::variant
is hashable. Previously we disable hashing when std::hash<T>()(key) was
formed but when std::hash<T> couldn't be destructed. This seems wrong. If a
user provides a evil specialization of std::hash, then it's OK for variant's
hash to blow up.

absl: cap SpinLock backoff to 4ms
The current backoff logic has 3 problems:
1. It can produce too high values (up to 256ms), which can negatively
affect tail latency. The value was chosen long time ago and now it's
a good idea to reconsider it.
2. It does not have low bound, so on any iteration it can produce
a very small value that will lead to unnecessary cpu consumption.
3. It does not increase low bound with the number of iterations.
So if the SpinLock is actually somehow locked for a very prolonged time,
a waiter can still wake periodically.
Rework the logic to solve these problems.
Add lower bound of 128us, no code should rely on absence of episodic
delays in this range as they can occur everywhere.
Lower upper bound to 4ms. A thread sleeping for 4ms does not consume
significant cpu time (see below).
Grow lower bound with the number of iterations.
This is cpu consumption of a process doing usleep(x) in a loop
(sampled with ps):
64us -> 4.0%
128us -> 2.7%
256us -> 3.5%
512us -> 2.8%
1024us -> 1.6%
2048us -> 0.6%
4096us -> 0.3%
8192us -> 0.0%
Few millisecond sleeps do not consume significant time.

Add a constructor to allow for global absl::Mutex instances.
This adds a new constexpr constructor to absl::Mutex, invoked with the absl::kConstInit tag value, which is intended to be used to construct Mutex instances with static storage duration.
What's tricky about is absl::Mutex (like std::mutex) is not a trivially destructible class, so by the letter of the law, accessing a global Mutex instance after it is destroyed results in undefined behavior. Despite this, we take care in the destructor to not invalidate the memory layout of the Mutex. Using a kConstInit-constructed global Mutex after it is destroyed happens to work on the toolchains we use. Google relies heavily on this behavior internally.
Code sanitizers that detect undefined behavior are able to notice use-after-free of globals, and might complain about this pattern.

Use a shim #define for wchar_t in msvc in int128.
On ancient versions of msvc and with some compatibility flags on wchar_t is a typedef for unsigned short, whereas on standards-conforming versions wchar_t is a typedef for __wchar_t. The first situation causes int128 to not compile as you can't define both `operator wchar_t()` and `operator unsigned short()` because they are the same type.
This CL introduces a wrapper #define in order to abstract over the different typedefs for wchar_t. We do a define instead of a typedef so that we can #undef at the end and not leak the symbol, since we need it in a header.
https://docs.microsoft.com/en-us/previous-versions/dh8che7s(v=vs.140) has more detail about the underlying problem.

Generate Abseil compile options. The single source of truth is now absl/copts/copts.py
The way this works goes something like this:
copts.py acts as the configuration file. We use python because unlike JSON it allows comments. It has two maps in it: one from names to external flags, and one from names to internal flags.
generate_copts.py imports the maps and loops through them to write GENERATED_copts.bzl and GENERATED_AbseilCopts.cmake
AbseilConfigureCopts.cmake and configure_copts.bzl import their respective copts args and set the platform-appropriate copts into ABSL_DEFAULT_COPTS, ABSL_TEST_COPTS, ABSL_EXCEPTIONS_FLAG, and ABSL_EXCEPTIONS_LINKOPTS
For Bazel, each BUILD file load()s configure_copts.bzl
For CMake, AbseilHelpers.cmake include()s AbseilConfigureCopts.cmake to get the final copts and both inserts them as needed into legacy target rules and also makes them available to the rest of our CMakeLists.txt file. We may instead want to include() AbseilConfigureCopts.cmake directly into each CMakeLists.txt file for consistency, but I'm not sure what the deal is with cmake and include guards, or if they are even needed. That's also not as idiomatic -- CMake tends to use directory scope where globals set at a higher level CMakeLists.txt file are used in the subdirectory CMakeLists.txt files.

absl: cap SpinLock backoff to 4ms
The current backoff logic has 3 problems:
1. It can produce too high values (up to 256ms), which can negatively
affect tail latency. The value was chosen long time ago and now it's
a good idea to reconsider it.
2. It does not have low bound, so on any iteration it can produce
a very small value that will lead to unnecessary cpu consumption.
3. It does not increase low bound with the number of iterations.
So if the SpinLock is actually somehow locked for a very prolonged time,
a waiter can still wake periodically.
Rework the logic to solve these problems.
Add lower bound of 128us, no code should rely on absence of episodic
delays in this range as they can occur everywhere.
Lower upper bound to 4ms. A thread sleeping for 4ms does not consume
significant cpu time (see below).
Grow lower bound with the number of iterations.
This is cpu consumption of a process doing usleep(x) in a loop
(sampled with ps):
64us -> 4.0%
128us -> 2.7%
256us -> 3.5%
512us -> 2.8%
1024us -> 1.6%
2048us -> 0.6%
4096us -> 0.3%
8192us -> 0.0%
Few millisecond sleeps do not consume significant time.

Make the absl::c_set_xxxx() algorithms refuse to compile when passed an unordered collection from std:: or absl::.
These algorithms operate on sorted sequences; passing an unordered container to them is nearly certainly a bug. This change is technically an API break, but it only breaks incorrect code.
We could try to be more clever and detect unordered collections from other libraries, but false positives will break legal code, and this would constitute an API break Abseil cannot afford.

MSVC 2017's STL throws a Structured Exception (not a C++ exception, essentially equivalent to SIGSEGV) when variant::emplace calls a throwing constructor when using the debug multithreaded MSVC runtime DLL. This manifests in dbg mode in Bazel builds. Disable tests which trigger this bug.
It's impossible to specifically pull out MSVC 2017 -dbg modes because there's no way for Bazel to know when version of MSVC is being used -- you tell Bazel the directory where the MSVC tools live, not which version of MSVC tools to use. Thus the best we can do is switch on _DEBUG, which is set whenever the debug runtime is selected with the /MDd build flag, as in Bazel -dbg modes.

absl: fix SpinLock::EncodeWaitCycles
If a thread has ever observed or set kSpinLockSleeper, it must
never leave 0 in kWaitTimeMask because at this point it is
expected to wake subsequent threads. Current calculations in
EncodeWaitCycles can result in 0 in kWaitTimeMask and lead to
missed wakeups. This is mostly theoretical today, because
the futex call needs to finish within 128 cycles (futex can
return immediately without waiting, but 128 cycles still
look too low for this). But this can well fire in future
if we bump granularity and/or threshold for recording contention.
Use kSpinLockSleeper instead of 0.

absl: optimize SpinLock::SlowLock
Currently we record contention even after the first initial spin.
This leads to several performance issues:
1. If we succeed in acquiring the lock after the initial spin,
overall wait time can be within tens/hundreds of nanoseconds.
Recording such low wait time looks completely unnecessary and excessive.
From some point of view this is not even a wait, because we did not sleep.
And, for example, Mutex does not record contention in this case.
In majority of cases the lock should be acquired exactly during the initial
spin, yet we still go through full overhead of submitting contention.
2. Whenever a thread submits contention it also calls FUTEX_WAKE
(there is no way to understand if it's necessary or not when wait value
is stored in the lock). So if there are just 2 threads and a brief
contention, the second thread will still call FUTEX_WAKE which
is completely unnecessary overhead.
Don't record contention after the initial spin wait.
FWIW this also removes 2 CycleClock::Now calls and EncodeWaitCycles
from the common hot path.

INFO: From Compiling tensorflow/core/kernels/crop_and_resize_op_gpu.cu.cc:
external/com_google_absl/absl/types/optional.h: In member function 'void absl::optional_internal::optional_data_dtor_base<T, <anonymous> >::destruct()':

data_.~T();
I've also seen similar compilation failures online, for flat_hash_map:
https://devtalk.nvidia.com/default/topic/1042599/nvcc-preprocessor-bug-causes-compilation-failure/
The bug is always around unnamed template parameters. Therefore, the workaround is to make them named.

22947b48ce4a1ba71ad4794f762235dac3a1df12 by Greg Falcon <gfalcon@google.com>:
The from_chars implementation incorrectly assumed `uint32_t` was `unsigned int`.
`strings_internal::BigUnsigned` had `uint32_t` and `uint64_t` constructors; when both of these types differ from `unsigned int`, `BigUnsigned(1u)` is ambiguous (neither conversion is better).
Fix this by removing the `uint32_t` constructor. When the `uint64_t` constructor is called with a literal or type that is 32 bits or narrower, the compiler is smart enough to optimize away the two-word case, so this fix is free.

Correctly define ABSL_HAVE_STD_STRING_VIEW for MSVC 2017. Currently the macro
is not defined even though MSVC 2017 provides `std::string_view`, and this
means both `absl::string_view` and `std::string_view` exist as distinct types.
A bunch of places relying on the false assumption that
`string_view::const_iterator` is `const char*` have to be fixed to build
successfully.

Define UNALIGNED_LOAD/STORE macros for UNDEFINED_BEHAVIOR_SANITIZER.
When using UBSan in trap mode (that is, without the ubsan runtime library), the
x86 macros can cause alignment errors as they assume unaligned loads/stores are
permitted. The macros defined in the presence of
{ADDRESS,THREAD,MEMORY}_SANITIZER require the runtime library.

Address test flakiness in the TimeoutTest.
The basic idea is to loop forever until the expected
scheduling delays are observed (within reasonable bounds),
and only then assert the other invariants.
