merge all pkgconfig-found libraries into a single one and redirect all
existing lib files to the merged variant. the clean separation between
libraries is largely fictional anyway because the main config block is
in libstore and cannot reasonably be moved out, or because libutil has
assumptions built into its behavior that libmain later establishes, or
because libexpr messes with global boehmgc configuration. nearly every
kind of layering violation imaginable can be found *some*where in lix,
and not pretending that this is not the case will let us clean up some
of them. this will also allow us to merge these libraries at the meson
level which is itself necessary to make rust code easier to integrate.

xattrs scrubbing was gated behind Linux platforms, but Lix can safely
assume that POSIX APIs are available.
macOS implements these APIs modulo some creative ideas.

Fixes#838.
xattrs were historically disabled in 2017, since then, NFS v4.2 gained
support for xattrs and almost all filesystems support xattrs. In
addition, moving the build directory to a xattrs-supporting filesystem
is always an option. Programs may exploit xattrs (including ACLs) during
their build process and testing phase, to better serve these programs,
we will remove this limitation.
Lix will use POSIX ACLs for its UNIX domain sockets in the future and be
one of these programs which will run tests making use of xattrs, while
not writing any xattrs in the derivation outputs themselves.
xattrs are still scrubbed from derivation outputs so it is not possible
to obtain an advantage by writing a security-related xattr to a well
chosen file.
Tests were added to test these scenarios on Linux. Darwin is carefully
excluded because of #1008 and #1090, solving that is welcome. In the
meantime, they are marked xfail.

I don't know how this was missed or no one really complained about it,
but perl-bindings was using CppNix if nix was not overlaid to our own
Lix.
If you overlay Lix manually, the resulting Lix's perl-bindings cannot
really refer to Lix itself, therefore, it's CppNix.

during the value rewrite we accidentally broke extension of incomplete
primop application. this only shows up when binding on incomplete call
to a primop to a name, binding an incomplete call to *that* to another
name, and then finally calling the second binding with enough args for
a complete primop application. since this only shows up when calling a
primop with three or more args it took a while to surface. we have few
builtins that match this: foldl', replaceStrings, and substring. these
are not used incompletely in this manner very often, so this lingered.

RegisterCommand was renamed in b30556f8f1
and de-static-ified in 4d9fe67430. adding
new settings was never possible with static instances since settings do
need an existing Config instance during construction; GlobalConfig must
be used to add settings. it is not possible to change existing configs.

Since lix-doc is no longer a separate library, the pkg-config files were broken
for static builds. Adjust them to refer to the new monocrate library instead.
Actually, since the monocrate library is static in all cases it needs to be
linked explicitly even when everything else is linked dynamically. I assume
this only doesn't break the dynamic nix-eval-jobs because it doesn't actually
use anything from it.

When --check is ran with no output, this is seen as having *SOME*
invalid outputs, actually, ALL of them are invalid here.
Instead of reporting a confusing error, let's consider ALL of outputs
being invalid to be no output at all available and advise the user to
rerun the build without --check.
If there's *some* (>0) invalid outputs, let's print them exactly to give
a chance to the user to remediate this.

Yeah uh, I don't think `$shell` is ever set in the functional1
environment. Pretty sure this has been expanding to `''` THIS WHOLE
TIME.
Also `SHELL` is `/sbin/nologin` in that builder. idk why so I'm just
passing `shell` unconditionally in functional's `mkDerivation` helper.
Maybe next we should put `set -euo pipefail` into all these test
builders?

macos-builder02 in particular has been having problems for a while now
that no one could reproduce. We believe we have finally found the cause:
missing shebangs, not just in the tests themselves but *also* in the
inline scripts `nix-shell` itself writes.

When `:load`-ing a file that doesn't result in a successful outcome, the
"loaded" file is removed again from the list of loaded files.
This avoids having it be used as part of `:reload` which will probably
not result in a positive outcome.
Instead, the user is expected to retry `:load` before issuing a
`:reload`.
Fixes#50.

If `:reload` is used with no file loaded, the environment is completely
cleared.
That's a surprising behavior and one of the root cause behind #50.
Environment clear is only performed if there's files to reload.

This makes that the default for all builds... which I'm not sure is the
right option, but it is also very cheap to do so, and adding an entire
other Lix build just for static libraries (not to be confused with
static Lix) would be prohibitively expensive.

`build_env` is assumed to be a certain trivial environment, e.g. a
singleton search path.
An environment in general is either empty, contain one or more search
paths separated by a colon.
It seems that the intent was to set the `build_shell` first as a
prepended path in the managed environment then extend via the
`build_env` parts.
This fixes a usecase when the `BUILD_TEST_ENV` is non-trivial.
