Arthur Gautier 3b72741f23 preloadNSS: load NSS before threads are started
preloadNSS is not thread-safe, this commit moves it before we start the
first thread.

Arthur Gautier 0b42a0f781 preloadNSS: fixup nss_dns load
Before this commit, the dns lookup in preloadNSS would still go through
nscd. This did not have the effect of loading the nss_dns.so as expected
(nss_dns.so being out of reach from within the sandbox).

Should LOCALDOMAIN environment variable be defined, nss will completely
avoid nscd and will do its dns resolution on its own.

By temporarly setting LOCALDOMAIN variable before calling in NSS, we can
force NSS to load the shared libraries as expected.

Fixes #5089

regnat 497225b07d Don’t create lockfiles with an invalid path name
Store paths are only allowed to contain a limited subset of the
alphabet, which doesn’t include `!`. So don’t create lockfiles that
contain this `!` character as that would otherwise confuse (and break)
the gc.

Install pkg-config files in the correct location
Use `$(libdir)` while installing .pc files looks like a more generic
solution. For example, it will work for distributions like RHEL or
Fedora where .pc files are installed in `/usr/lib64/pkgconfig`.

Andreas Rammhold a9cb1ca32c libstore: use set instead of list for waiter list
This replaces the O(n) search complexity in our insert code with a
lookup of O(log n). It also makes removing waitees easier as we can use
the extract method provided by the set class.

Andreas Rammhold b2d3976163 Fix potential race-condition in reference scanning code
Previously the code ensures that the isBase32 array would only be
initialised once in a single-threaded context. If two threads happen to
call the function before the initialisation was completed both of them
would have completed the initialization step. This allowed for a
race-condition where one thread might be done with the initialization
but the other thread sets all the fields to false again. For a brief
moment the base32 detection would then produce false-negatives.

regnat d9ba3385a9 Don’t send the experimental-features to the daemon
The experimental features are, well, experimental, and shouldn’t be
carelessly and transparently enabled.
Besides, some (`ca-derivations` at least) need to be enabled at startup
in order to work properly.
So it’s better to just require that daemon be started with the right
`experimental-features` option.

Eelco Dolstra fe1f34fa60 Low-latency closure copy
This adds a new store operation 'addMultipleToStore' that reads a
number of NARs and ValidPathInfos from a Source, allowing any number
of store paths to be copied in a single call. This is much faster on
high-latency links when copying a lot of small files, like .drv
closures.

For example, on a connection with an 50 ms delay:

Before:

  $ nix copy --to 'unix:///tmp/proxy-socket?root=/tmp/dest-chroot' \
    /nix/store/90jjw94xiyg5drj70whm9yll6xjj0ca9-hello-2.10.drv \
    --derivation --no-check-sigs
  real    0m57.868s
  user    0m0.103s
  sys     0m0.056s

After:

  real    0m0.690s
  user    0m0.017s
  sys     0m0.011s

Eelco Dolstra eb6db4fd38 buildPaths(): Add an evalStore argument
With this, we don't have to copy the entire .drv closure to the
destination store ahead of time (or at all). Instead, buildPaths()
reads .drv files from the eval store and copies inputSrcs to the
destination store if it needs to build a derivation.

Issue #5025.

Eelco Dolstra 8d9f7048cd Use eval-store in more places
In particular, this now works:

  $ nix path-info --eval-store auto --store https://cache.nixos.org nixpkgs#hello

Previously this would fail as it would try to upload the hello .drv to
cache.nixos.org. Now the .drv is instantiated in the local store, and
then we check for the existence of the outputs in cache.nixos.org.

Add use-registries config option (and deprecate --no-registries flag)
Some people want to avoid using registries at all on their system; Instead
of having to add --no-registries to every command, this commit allows to
set use-registries = false in the config. --no-registries is still allowed
everywhere it was allowed previously, but is now deprecated.

regnat a4ec6cb1da Be more lenient when realisations have a conflicting dependency set
- This can legitimately happen (for example because of a non-determinism
  causing a build-time dependency to be kept or not as a runtime
  reference)
- Because of older Nix versions, it can happen that we encounter a
  realisation with an (erroneously) empty set of dependencies, in which
  case we don’t want to fail, but just warn the user and try to fix it.
