These are required for tvixbolt to work. This interface is definitely
not stable yet, though.

This type implements an observer that is called whenever the compiler
emits a chunk (after the toplevel, thunks, or lambdas) and prints the
output of the disassembler to its internal writer.
This replaces half of the uses of the `disassembler` feature, which
has been removed from the Cargo configuration.
Note that at this commit runtime tracing is not yet implemented as an
observer.

This trait will enable library users of tvix-eval to observe internal
happenings of the compilation and runtime processes.
The initial methods of the observer will be called whenever the
compiler emits a chunk.

This trait abstracts over the commonalities of upvalue handling
between closures and thunks.
It allows the VM to simplify the code used for setting up upvalues,
without duplicating between the two different types.
Note that this does not yet refactor the VM code to optimally make use
of this.

Adds a new builtins module in which builtins can be constructed. The
functions in this module should return a correctly structured value to
be passed to the compiler's `globals`.
This is wired up all the way to the compiler with an example
`toString` builtin, available as a global. Note that this does not yet
actually behave like the real toString, which has some differences
from `Display`.

This adds a `disassembler` feature to the crate configuration that
traces the operations executed and the state of the stack at runtime.
This can be enabled by compiling with `--feature disassembler`.
This will also gain a more sensible layout of code slices eventually.

These can be used predominantly to emit warnings about things that the
compiler can infer, such as deprecated language features.

Add a new `lib.rs` to tvix/eval, which `pub use`s the `interpret`
function, and all types mentioned in its return type, and then uses
*this* instead of direct `mod` statements in the `main.rs` to implement
the entrypoints to the interpreter. This is in preparation for calling
these functions from integrated benchmarking infrastructure using
Criterion, though other things (like integration tests) might want to do
that as well.
