* changes:
Change error messages about 'invalid paths' to 'path does not exist'.
Add a clearer error message for InvalidPathError during evaluation
Harmonise the Store::queryPathInfoUncached interface
This:
- Consistently returns `nullptr` for a non-existent
store path, instead of a mix of `nullptr` and
throwing exceptions.
- If a store returns "bad" store paths in response
to a request (e.g. incorrect hash or name), don't
cache this result. This removes some duplication
of code at the cache-access layer of queryPathInfo()
checking this, and allows us to provide more
specific errors.
Part of #270.

FreeBSD uses libunwind unwind.h, which does not require
`_GNU_SOURCE` to expose `_Unwind_Backtrace`.
Tell Boost that.

It's in the security section, and it was totally outdated anyway.

They are enabled by default, and Meson will also prints whether or not
they're enabled at the bottom at the end of configuration.

$ rg '((?!(recursive).*) Nix

-g '!doc/' --pcre2
All items from this query have been tackled. For the documentation side:
that's for lix-project/lix#162.
Additionally, all remaining references to github.com/NixOS/nix which
were not relevant were also replaced.

This causes libstore, libexpr, libfetchers, and libutil to be linked
with -Wl,--whole-archive to executables, when building statically.
libstore for the store backends, libexpr for the primops, libfetchers
for the fetcher backends I assume(?), and libutil for the nix::logger
initializer (which notably shows in pre-main constructors when HOME is
not owned by the user. cursed.).
This workaround should be removed when #359 is fixed.
Fixes#306.

Previously the entire escaped store URI was included. This would cause
build failures if a very long or deeply nested path was being used in
the store.
Now, we use the first 48 characters of the URL (escaped), then 16 bytes
of hash of the entire URL. This should never collide and limits the
length of the file name to a bit over 64, which is fine.

This is because a dynamic_cast<nix::RootArgs *> of a (n-e-j) MyArgs
returns nullptr even though MyArgs has virtual nix::RootArgs as a
parent.
class MyArgs : virtual public nix::MixEvalArgs,
virtual public nix::MixCommonArgs,
virtual nix::RootArgs { ... };
So this should work right?? But it does not. We found out that it's
caused by -fvisibility=hidden in n-e-j, but honestly this code was bad
anyway.
The trivial solution is to simply stop relying on RTTI working properly
here, which is probably better OO architecture anyway. However, I am not
100% confident *this* is sound, since we have this horrible hierarchy:
Args (defines getRoot)
/ | \
RootArgs MixCommonArgs MixEvalArgs
(overrides)
I am not confident that this is guaranteed to resolve from Args always
in the case of this override.
Assertion failed: (res), function getRoot, file src/libutil/args.cc, line 67.

We also found that if we did this:

it would work properly (???!). This is of course, very strange, because
objdump -Ct output on liblixexpr.dylib is identical both with and
without it.

It seems like someone implemented precompiled headers a long time ago
and then it never got ported to meson or maybe didn't work at all.
This is, however, blessedly easy to simply implement. I went looking for
`#define` that could affect the result of precompiling the headers, and
as far as I can tell we aren't doing any of that, so this should truly
just be free build time savings.
Previous state:
Compilation (551 times):
Parsing (frontend): 1302.1 s
Codegen & opts (backend): 956.3 s
New state:
**** Time summary:
Compilation (567 times):
Parsing (frontend): 1123.0 s
Codegen & opts (backend): 1078.1 s
I wonder if the "regression" in codegen time is just doing the PCH
operation a few times, because meson does it per-target.

We reviewed this code a while ago, and we neglected to get a comment in
saying why it's Like This at the time. Let's fix that, since it is code
that looks very absurd at first glance.

while refactoring the curl wrapper we inadvertently broken the immutable
flake protocol, because the immutable flake protocol accumulates headers
across the entire redirect chain instead of using only the headers given
in the final response of the chain. this is a problem because Some Known
Providers Of Flake Infrastructure set rel=immutable link headers only in
the penultimate entry of the redirect chain, and curl does not regard it
as worth returning to us via its response header enumeration mechanisms.
