jade e6e5cacabe shellHook: make it actually run 
When we changed this in I91cb6eb6668f3a8eace36ecbdb01eb367861d77b to
not run in nested shells, we didn't predict that `nix develop` would do
something ridiculous and append -env to things silently. `nix-shell` of
course does not do this, so we need to tolerate both.

jade 533d469875 Revert "tests/filetransfer: reënable on Darwin" 
This reverts commit 285bc67318.

Reason for revert: lix-project/lix#364

For some reason this broke `main` even though the change we are reverting passed CI! Mysterious, haunted, etc. Needs more debugging, let's turn it off for now.

jade 7575db522e Remove 100s of CPU time (10%) from build times (1465s -> 1302s) 
I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.

Qyriad eac3546d50 package: return from shellHook correctly 
If our shellHook is being run from a nested nix-shell (see 7a12bc200¹),
then (I think) it is run from a bash function due to the nesting, then
`return` is correct. If its `eval`'d though, then there isn't really a
correct way to early exit. So we can just unconditionally be executed in
a function.

Basically, we have IIFE at home.

eldritch horrors dd4a2c1759 libstore: fix http abuses no longer working 
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.

grepQuietInvert is a typo introduced by c11836126b.

The test functional-timeout was failing silently because Bash considered
the command-not-found error as truthy.

terru - 7a12bc2007 package: don't run shellHook in nested nix-shells 
If a nested nix-shell is run inside a nix-shell, then the outer shell's
shellHook will be passed through and run again, unless the nested shell
defines its own.

With lix's hook, this can be annoying: forgetting to exit its nix-shell,
cd'ing to another repository & entering a nested nix-shell will happily
install lix's pre-commit hook in it.

This change makes lix's hook return early in such cases.

terru - 0b91a4b0ec shell.nix: conform to documentation 
According to doc/manual/src/contributing/hacking.md, all development
shells should also be available in classic nix using the -A argument
to nix-shell, e.g.

  nix-shell -A native-clangStdenvPackages

This was not actually the case; flake-compat generates attrsets like

  nix-shell -A devShells.x86_64-linux.native-clangStdenvPackages

instead. These are unwieldy to use, so rather than changing the docs,
this changes the shell.nix file to result in the documented behavior.

eldritch horrors ed6b3165ea worker: process timeouts first, and exclusively 
check goals for timeouts first, and their activity fds only if no
timeout has occurred. checking for timeouts *after* activity sets
us up for assertion failures by running multiple build completion
notifiers, the first of which will kill/reap the the goal process
and consuming the Pid instance. when the second notifier attempts
to do the same it will core dump with an assertion failure in Pid
and take down not only the single goal, but the entire daemon and
all goals it was building. luckily this is rare in practice since
it requires a build to both finish and time out at the same time.

writing a test for this is not feasible due to how much it relies
on scheduling to actually trigger the underlying bug, but on idle
machines it can usually be triggered by running multiple sleeping
builds with timeout set to the sleep duration and `--keep-going`:

    nix-build --timeout 10 --builders '' --keep-going -E '
      with import <nixpkgs> {};
      builtins.genList
        (i: runCommand "foo-${toString i}" {} "sleep 10")
        100
    '
