libstore: Fix sandbox=relaxed
The fix for the Darwin vulnerability in ecdbc3b207
also broke setting `__sandboxProfile` when `sandbox=relaxed` or
`sandbox=false`. This cppnix change fixes `sandbox=relaxed` and
adds a suitable test.

repl: show a progress bar while performing builds
In commit 946fc12e4e, the progress bar in the
repl was disabled again because it was observed to erase incremental output
from attrset evaluations from the terminal. Let's try adding the progress bar
again, this time showing up only when a build is initiated, which does not have
incremental output that could be destroyed to begin with. While this does mean
that we won't have a progress bar for eval-time fetching or IFD, it's still
better than nothing.

Qyriad f782c8a60a flake: refactor devShell creation
Now instead of a derivation overridden from Lix, we use a mkShell
derivation parameterized on an already called package.nix. This also
lets callPackage take care of the buildPackages distinction for the
devShell.

Always initialize curl in parent process on darwin
Because of an objc quirk[1], calling curl_global_init for the first time
after fork() will always result in a crash.
Up until now the solution has been to set
OBJC_DISABLE_INITIALIZE_FORK_SAFETY for every nix process to ignore
that error.
This is less than ideal because we were setting it in package.nix,
which meant that running nix tests locally would fail because
that variable was not set.
Instead of working around that error we address it at the core -
by calling curl_global_init inside initLibStore, which should mean
curl will already have been initialized by the time we try to do so in
a forked process.

eldritch horrors 964ac8b0e8 libutil: de-callback-ify computeClosure
only two users of this function exist. only one used it in a way that
even bears resemblance to asynchronicity, and even that one didn't do
it right. fully async and parallel computation would have only worked
if any getEdgesAsync never calls the continuation it receives itself,
only from more derived callbacks running on other threads. calling it
directly would cause the decoupling promise to be awaited immediately
*on the original thread*, completely negating all nice async effects.

Qyriad 005b2b61e6 fix fallback chroot store creation after b247ef72d
When /nix/var (or, more precisely, NIX_STATE_DIR) does not exist at all,
Lix falls back to creating an adhoc chroot store in XDG_DATA_HOME.

b247ef72d[1] changed the way Store classes are initialized, and in the
migration, a `params2` was accidentally changed to `params`. This commit
restores the correct behavior, and in lieu of a single *character* fix,
this commit also changes the variable name to something more reasonable.

Fixes #274.

[1]: b247ef72dc

n.b., this code might deserve some more looking at anyway. this fallback
store creation throws away *all* Store params passed to
openFromNonUri() in favor of an entirely new set which only contains
the `root` param, which may or may not be the correct behavior

eldritch horrors f75d0752ce filetransfer: correctly abort empty transfers
returning 0 from the callback for errors signals successful transfer if
the source returned no data even though the exception we've just caught
clearly disagrees. while this is not all that important (since the only
viable cause of such errors will be dataCallback, and the sole instance
of it being used already takes care of exceptions) we can just do this.

Fix failing darwin tests
Some tests were failing on darwin,
if the auto-allocate-uids featrure was enabled.
This was because AAU on darwin works by setuid-ing as a non-existent
user, so the tests that were relying on `whoami` were failing.

In the case of trusted-users we fall back to printing the user id,
which is already handled gracefully in the daemon code - i.e. when
a user does not exist or for some other reason looking up their
username is not possible, the daemon falls back to searching for their
uid inside the trusted-users list.

When whoami is used to print the username for other purpose,
we default to printing nixbld.

jade 748d8310fa Fix the pages in the manual for Lix
This doesn't comprehensively fix everything outdated in the manual, or
make the manual greatly better, but it does note down where at least
jade noticed it was wrong, and it does fix all the instances of
referencing Nix to conform to the style guide to the best of our
ability.

A lot of things have been commented out for being wrong, and there are
three types of FIXME introduced:

- FIXME(Lix): generically Lix needs to fix it
- FIXME(Qyriad): re lix-project/lix#215
- FIXME(meson): docs got outdated by meson changes and need rewriting

I did fix a bunch of it that I could, but there could certainly be
mistakes and this is definitely just an incremental improvement.

Qyriad 99903f24eb fix integer overflow on i686 with high phys memory
sizeof(long) is 4 bytes on i686 GCC.
With ~32 GiB of memory and a page size of 4096, there are 7988420 pages.
(7988420 * 4096) is bigger than INT32_MAX folks.

This has gone unnoticed for 9 years, and only came up thanks to
94ea517db[1] adding integer overflow sensitization checks, which caused
this broken code to emit an illegal instruction, crashing Lix the
instant the buildsystem ran Lix to generate the docs files.
