dcb39d3198 feat(ops/nixos/camden): Index nixpkgs in hound
There is a local nixpkgs clone at /var/git/nixpkgs which must be
manually set to have 'master' point at the desired ref (hound only
supports master).

68e384a77f ffeat(ops/nixos): Add a dummy to make depot available in modules
Because modules are not called via the default depot setup (for now
...), this introduces a dummy module that stores the depot tree itself
in the module configurations.

This makes it possible to write modules that use packages from the
depot.

bf452cbc2a refactor(3p/nix): Replace tokenizeStrings with absl::StrSplit
This function was a custom (and inefficient in the case of
single-character delimiters) string splitter which was used all over

98299da0fd refactor(3p/nix/libutil): Replace string2Int & trim functions
Replaces these functions with corresponding functions from Abseil,
namely absl::StripAsciiWhitespace and absl::SimpleAtoi.

In the course of doing this some minor things I encountered along the
way were also refactored.

This also changes the signatures of the various custom readFile
functions to use absl::string_view types.

838f86b0fd style(3p/nix): Remove 'using std::*' from types.hh
It is considered bad form to use things from includes in headers, as
these directives propagate to everywhere else and can make it
confusing.

types.hh (which is includes almost literally everywhere) had some of
these directives, which this commit removes.

2c86856ca7 Add a new template system
Add a parser, pretty-printer, and renderer for a new template system,
which should eventually be a drop-in replacement for the current
mustache-based template system, but also supports text filters (which
will be used for things like pluralization and noun casing). Nothing
currently uses it yet, though.

bac38f3c49 fix(3p/nix): Fix long paths permanently breaking GC
Suppose I have a path /nix/store/[hash]-[name]/a/a/a/a/a/[...]/a,
long enough that everything after "/nix/store/" is longer than 4096
(MAX_PATH) bytes.

Nix will happily allow such a path to be inserted into the store,
because it doesn't look at all the nested structure.  It just cares
about the /nix/store/[hash]-[name] part.  But, when the path is deleted,
we encounter a problem.  Nix will move the path to /nix/store/trash, but
then when it's trying to recursively delete the trash directory, it will
at some point try to unlink
/nix/store/trash/[hash]-[name]/a/a/a/a/a/[...]/a.  This will fail,
because the path is too long.  After this has failed, any store deletion
operation will never work again, because Nix needs to delete the trash
directory before recreating it to move new things to it.  (I assume this
is because otherwise a path being deleted could already exist in the
trash, and then moving it would fail.)

This means that if I can trick somebody into just fetching a tarball
containing a path of the right length, they won't be able to delete
store paths or garbage collect ever again, until the offending path is
manually removed from /nix/store/trash.  (And even fixing this manually
is quite difficult if you don't understand the issue, because the
absolute path that Nix says it failed to remove is also too long for
rm(1).)

This patch fixes the issue by making Nix's recursive delete operation
use unlinkat(2).  This function takes a relative path and a directory
file descriptor.  We ensure that the relative path is always just the
name of the directory entry, and therefore its length will never exceed
255 bytes.  This means that it will never even come close to AX_PATH,
and Nix will therefore be able to handle removing arbitrarily deep
directory hierachies.

Since the directory file descriptor is used for recursion after being
used in readDirectory, I made a variant of readDirectory that takes an
already open directory stream, to avoid the directory being opened
multiple times.  As we have seen from this issue, the less we have to
interact with paths, the better, and so it's good to reuse file
descriptors where possible.

I left _deletePath as succeeding even if the parent directory doesn't
exist, even though that feels wrong to me, because without that early
return, the linux-sandbox test failed.
