Previously, the code which parsed comments in key files would append a
line break to the comment where there was none before; this was part of
the code for handling re-inserting line breaks into multi-line comments
after removing the ‘#’ prefix. Now, we don’t add a terminal line break.
This was slightly icky to implement because parse_value_as_comment() is
called once for each line of a multi-line comment.
This expands the existing test case to cover a single line comment, and
also fixes the documentation to correctly state that the leading ‘#’
*is* removed and mention the new line break behaviour.

* Wait for adder threads before deallocating crawler_array and
context_array to avoid use after-free and data race.
* Handle spurious wakeups around g_cond_wait.
* Avoid starting recurser_idle without context.
Fixes issue #1530.
When g_date_set_parse was used with more than one locale it could
incorrectly retain information from previous one. Reinitialize all
locale specific data inside g_date_prepare_to_parse to avoid the issue.
This is the most degenerate possible test but it does exercise this code
path.
(Tweaked by Philip Withnall <withnall@endlessm.com> to also add the flag
to the autotools build.)
g_source_set_callback() and g_source_set_callback_indirect() are both
safe to call zero or more times on attached sources. The change in
callback will take effect the next time the source is dispatched, after
the set_callback() call returns (it could block due to locking).

FreeBSD 12 adds a new header, sys/auxv.h, to declare a function, elf_aux_info,
for public use, which was considered an internal function in previous releases.
This new function provides similar functionality with glibc getauxval, which is
also declared in the same header, but their interfaces are not compatible. Since
the only usage of sys/auxv.h is in g_check_setuid and FreeBSD already has
issetugid to provide the required functionality, we fixes the compilation error
by adding a check for getauxval function to prevent g_check_setuid from calling
getauxval when sys/auxv.h is found but getauxval is not available.

Previously, the markup parsing test would load a given markup file and
try to parse it several ways. It would return as soon as one of the
attempts failed — meaning that bugs only seen with non-nul-terminated,
or differently chunked, parse runs could never be caught.
Rework the tests so that all markup files are tested all ways, and we
assert that all ways of parsing them give the same result.

Previously, the element name validation only happened if a start_element
callback was specified on the context. Element name validation should be
unconditional.
This was causing test-5.gmarkup to fail when run against the improved
tests in the following commit.

When extracting a UTF-8 character to put in an error message on parse
failure, pass the remaining buffer length to utf8_str() to avoid it
running off the end of the input buffer. It previously assumed that the
buffer was nul-terminated, which was the case in all the tests until
now.
A following commit will add test coverage for this.

When using GMarkup to parse a string, the string can be provided with an
explicit length specified, or with no length and a nul terminator
instead. Run all the GMarkup tests both ways, to catch problems with
length checks, or with nul terminator checks.

This doesn’t trigger any new failures, but is distinct from other tests
we have, so would be good to retain.

The executable depends only on the generated header file at compile
time, and on the library at link time. So meson can decide to compile
gdbus-peer.c before compiling the library and thus won't have generated
the header yet, causing the build error.
So declare_dependency() should only have the header file in its sources,
to force generating files before compiling gdbus-peer.c without
including objectmanager-gen.c into gdbus-peer's sources.
We use libgdbus_example_objectmanager_dep as dependency for various
tests, but this implies only a link dependency while it doesn't ensure
that the sources are generated.

mntent-based implementation filter out mounts with device path that was
repeated. Consequently, it is not possible to show such mounts in UI even
with x-gvfs-show, because they are not returned from g_unix_mounts_get.
libmount-based implementation currently doesn't filter out any mounts
which causes issues to our volume monitors. Let's rather mark mounts
which don't point into fs root as system_internal. This approach won't be
affected by mount order as is mntent-based implementation. It will mark
more mounts as system_internal than it is filtered out with mntend-based
implementation, but there will be always possibility to show them in UI
over x-gvfs-show, which was not possible with mntend-based. We can
probably introduce some improvements later to not mark unique mounts as
system internal even if they don't point into fs root...

Currently, there isn't API to determine root path for mounts created
over bind operation (or btrfs subvolumes). This causes issues to our
volume monitors if there is multiple mounts for one device, which can
happen with libmount-based implementation currently. Let's propagate
root path from libmount over g_unix_mount_get_root_path, so we can
handle this somehow in our volume monitors.

Currently, readlink() is used only 12 times when expanding symlinks.
However, kernel uses 40 for this purpose and it is defined as MAXSYMLINKS.
Use that constant if available, or 40. See:
https://github.com/torvalds/linux/include/linux/namei.h.
find_mountpoint_for() uses current file in case of error, because
get_parent() returns NULL for error, but also if parent doesn't exist.
Return "." from get_parent() if parent doesn't exist in order to
differentiate the error state.
Test symlink expansion in find_mountpoint_for() function over
_g_local_file_find_topdir_for(). find_mount_for() is crucial for many
of glocalfile.c functionality (e.g. to determine correct trash location)
and symlink expansion has to work properly.

These were callers which explicitly specified the string length to
g_utf8_validate(), when it couldn’t be negative, and hence should be
able to unconditionally benefit from the increased string handling
length.
At least one call site would have previously silently changed behaviour
if called with strings longer than G_MAXSSIZE in length.
Another call site was passing strlen(string) to g_utf8_validate(), which
seems pointless: just pass -1 instead, and let g_utf8_validate()
calculate the string length. Its behaviour on embedded nul bytes
wouldn’t change, as strlen() stops at the first one.

This is a variant of g_utf8_validate() which requires the length to be
specified, thereby allowing string lengths up to G_MAXSIZE rather than
just G_MAXSSIZE.

This introduces no real functional changes (except when compiling with
G_DISABLE_ASSERT, in which case it fixes the test). Mostly just a code
cleanup.

The code was checking whether the signature provided by the blob was a
valid D-Bus signature — but that’s a superset of a valid GVariant type
string, since a D-Bus signature is zero or more complete types. A
GVariant type string is exactly one complete type.
This meant that a D-Bus message with a header field containing a variant
with an empty type signature (for example) could cause a critical
warning in the code parsing it.
Fix that by checking whether the string is a valid type string too.
Unit test included.
