513634ab5b Make cgroup.{cc,hh} linux-only files 
Forcing a conditional include, vs making the headers content
conditional, I think is more maintainable.

It is also how the other platform-specific headers (like
`namespaces.hh`) have been adapted.

c145ce0e1a realiseContext: Remove no-op replacements 
A possible use of them might have been to figure out the paths
(which can now be retrieved with maybePathsOut), but I have
not found evidence that it was used this way, and it would have
been broken, because non-CA outputs weren't recorded in the map.

unbroken.

ef2d10f7e7 Clean up env var logic in preparation for Windows 
It's a little weird we don't check the return status for these, but
changing that would introduce risk so I did not.

Improve checked json casting (#10087) 
This introduces new utility functions to get elements from JSON — in an ergonomic way and with nice error messages if the expected type does not match.

fix(libutil): apply only the specified filter to decompress archive 
This patch makes `makeDecompressionSink` strip only a single layer
of compression specified via method. This fixes erroneous decompression
of doubly-compressed NARs fetched with curl.

8be347afca Factor out nix::maybeLstat 
This function is nice for more than `PosixSourceAccessor`. We can make a
few things simpler with it.

Note that the error logic slightly changes in some of the call sites, in
that we also count `ENOTDIR` and not just `ENOENT` as not having the
file, but that should be fine.

555181c3fd throwExceptionSelfCheck throw Error 
`SysError` is not appropriate because there is no (Unix) syscall involved.

The catch block in `initLibUtil` is already for `Error` and still works.

enable persistent WAL mode for sqlite db 
allow processes without write access to the directory containing the db
to read the db when all connections are closed. Without this setting and
with WAL enabled and no open db connections unprivileged processes will
fail to open the db due the WAL files not existing and not able to
create them. When the WAL files are persistent unprivileged processeses
can read the db when there are no open connections.

Additionally, journal_size_limit is set to 2^40, which results in the
WAL files being truncated to 0 on exit, as well as limiting the WAL
files to 2^40 bytes following a checkpoint.
