We didn't even realize you *could* use this syntax with -E and -f, much
less that the attribute path could be *empty*.

* docs: unify documentation on search paths
- put all the information on search path semantics into `builtins.findFile`
- put all the information on determining the value of `builtins.nixPath` into the
`nix-path` setting
maybe `builtins.nixPath` is a better place for this, but those bits
can still be moved around now that it's all next to each other.
- link to the syntax page for lookup paths from all places that are
concerned with it
- add or clarify examples
- add a test verifying a claim from documentation
Few filesystem-related tests rely on PATH_MAX for buffers, and PATH_MAX
is optional in POSIX (and not available on the Hurd). To make them build
and pass, provide a fallback definition of PATH_MAX in case not
available.
Ideally speaking, the tests ought to not unconditionally rely on
PATH_MAX, do alternative strategies (e.g. dynamically allocate buffers,
expand them as needed, etc); OTOH this is test code, so it would be more
work that what it would be worth, so IMHO the define fallback is good
enough.
Set HOST_HURD & HOST_UNIX for GNU/Hurd in the makefile-based build
system; the latter variable is important as it will include all the
commit Unix bits.
- move <sys/resource.h> from a __linux__ block to a !_WIN32 block: this
matches what the actual code does, using getrlimit() & setrlimit() in
!_WIN32 blocks
- drop <sys/mount.h>, which is not portable, and it is not used

This change updates the seccomp profile to return ENOTSUP for getxattr
functions family. This reflects the behavior of filesystems that don’t
support extended attributes (or have an option to disable them), e.g.
ext2.
The current behavior is confusing for some programs because we can read
extended attributes, but only get to know that they are not supported
when setting them. In addition to that, ACLs on Linux are implemented
via extended attributes internally and if we don’t return ENOTSUP, acl
library converts file mode to ACL.

The internal "completionCallback" and "listPossibleCallback" helpers
are used only when building with editline; hence, do not build then
when using readline, matching their usage in
"ReadlineLikeInteracter::init()".
This seems to have been the intent all along.
The odd combination of unit tests, but no functional tests caused a
build error where some data for the unit test was source-filtered out.
Apparently. It's unclear to me why that happened, so I'm proposing this
alternate "fix" to get the buildNoTests to pass.
It would be nice to test more configurations, but this mode of building
is on the way out anyway, so let's just make it pass and see what
configurations make sense to test as part of the meson migration.
