Backport of https://github.com/NixOS/nix/commit/b244e65cdbc2949af70bd539bf8f3bd2fa952d07
Fixes https://github.com/NixOS/nix/issues/3175
------
Original fault description by puck:
I suspect I found the issue: The Nix Command structs are stored on the
heap (using ref<T>, a wrapper around std::shared_ptr<T>), which means
that any pointers that the NixRepl struct contains are eligible to be
reaped by the GC. This includes, but is not limited to, the Env
pointer, which seems to cause most of the random segfaults, or random
other values in the environment, which seems to be what @arianvp
experienced too.

malformed
Previously the nix-daemon would crash if a user fed it invalid store
paths for drv files. The crash was due to the changed assertion
triggering. Whenever that assertion would hit the nix-daemon process
along with all it's current childs (running builds from all users) would
be interrupted.
Before this patch:
$ nix-store --realise /nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
don't know how to build these paths:
/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
error: unexpected end-of-file
< nix-daemon terminates >
With this patch:
$ nix-store --realise /nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
don't know how to build these paths:
/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv
error: path '/nix/store/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.drv' is not a valid store path
< nix-daemon does *NOT* terminate >

This takes us about halfway through worker-protocol.hh
I have left out the documentation strings for some of these items
because I don't feel that I can currently write an unambigous
description of them. For now I am just attempting to match the types.

I send a lot of accidental newlines after messages because my muscle
memory is very intent on hitting "o" to get into insert mode.

I'm not actually sure if this will apply cleanly, because the new
NixOS ACME module is kind of broken.
