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.

We unconditionally appended ">= $min_glib_version" to the modules to
look for, even though we had already included
"glib-2.0 >= $min_glib_version" in our list. When requesting additional
modules, this was fine, for example
AM_PATH_GLIB_2_0([2.58], [:], [:], [gobject gio])
ended up asking pkg-config for
glib-2.0 >= 2.58 gobject-2.0 gio-2.0 >= 2.58
which is redundant (since they all share a version number) but
otherwise OK.
However,
AM_PATH_GLIB_2_0([2.58], [:], [:], [])
ended up asking pkg-config for
glib-2.0 >= 2.58 >= 2.58
which is not OK; the second ">=" was parsed as a bizarrely-named package
to check for, and obviously few people have ">=.pc" installed.

Fixes: 4bb16f48 "m4macros: Allow information from pkg-config to be overridden"
An assertion is harder to skip over, and using a g_critical() can give
us a more informative error message.

All pool threads are named "pool" and this a bit annoying when looking
at system-wide traces or statistics for a system where several
applications use thread pools. Include the prgname in the thread names
to get a better default name. The total length including the "pool-"
prefix is limited to 16 bytes in order for it to work on all systems.

Since we are unable to promote our FreeBSD runner to a shared runner,
we can only enable it in GNOME group. This should avoid problems when
submitting merge requests from forks.
While we can’t add markers to the macro implementations to cause lcov to
ignore them automatically, we can change our lcov configuration to
ignore all calls to them.
See https://github.com/linux-test-project/lcov/issues/44.
This causes all the un-takeable branches and un-reachable assertions to
be ignored by our code coverage, which bumps our statistics:
• Lines: 74.9% → 74.8%
• Functions: 82.3% → 82.3%
• Branches: 53.3% → 64.2%
The rationale is that nobody should be testing programmer error
handling, as g_return_*if_fail() are used to guard against — so it’s not
reasonable to count missed branches like that in code coverage
statistics.

By using PKG_CHECK_VAR, we declare $GLIB_COMPILE_SCHEMAS,
$GLIB_GENMARSHAL, $GOBJECT_QUERY, $GLIB_MKENUMS and
$GLIB_COMPILE_RESOURCES as Autoconf "precious variables" with AC_ARG_VAR,
similar to $PKG_CONFIG and $CC, so that they can be put on a configure
command line:
./configure GLIB_COMPILE_RESOURCES=my-glib-compile-resources
If they are set to a non-empty value, PKG_CHECK_VAR will use that
instead of auto-detecting from pkg-config, so that builders can
override them, for example when cross-compiling.
Similarly, use the standard PKG_CHECK_MODULES macro to get GLib's CFLAGS
and LIBS.
It's possible that most of the rest of each macro can also disappear,
but for the moment I've given them the benefit of the doubt.
This does result in printing "checking for GLIB" twice (once for
PKG_CHECK_MODULES and once for GLib's custom checks), but if you're
using Autotools, you probably don't have a strong objection to overly
verbose output.

The tests were making assumptions about the order of the returned D-Bus
introspection nodes. However, these are semantically unordered and
changes to e.g. GHashTable would break the tests.
Fix this by applying a sort prior to validation.
We still clear the key/value on removal, but since we're growing the
arrays with realloc() now, we can't guarantee that incoming memory is
cleared. There's no reason it should be either, since we check the
hashes array (which is always in a defined state) before accessing the
other arrays.
When g_hash_table_resize() gets called, we clear out tombstones and grow
the table at the same time if needed. However, the threshold was set too
low, so we'd grow if the load was greater than .5 after subtracting
tombstones. Increase this threshold to ~.75.
When resizing, we were keeping both the old and new hash, key and value
arrays around while we reinserted entries, resulting in a peak memory
overhead of 50%. Using a temporary bookkeeping array with one bit per
entry we can now grow and shrink the main arrays using realloc() and an
eviction scheme, reducing the overhead to .625% (assuming 64-bit keys and
values). Tests show the CPU overhead is negligible.
If int is smaller than void * on our arch, we start out with
int-sized keys and values and resize to pointer-sized entries as
needed. This saves a good amount of memory when the HT is being
used with e.g. GUINT_TO_POINTER().
I’m fed up of trying to read these and having my head done in by mixed
tabs and spaces.
This introduces no functional changes.

There are a lot of gbooleans in the private GTask struct, which seems a
bit wasteful. Use a bitfield to compress the struct a bit.
This reduces the size of the struct from 216 bytes to 168 bytes on my
64-bit machine.
One of the fields needs to remain separate, since it’s used from a
TRACE() macro which calls typeof() on it.

These functions already check to see if a successful result has already
been returned; expand them to also check to see if an error has been
returned.
We can’t just check GTask.result_set, as that’s actually an indicator
for whether the GTask.result member is filled — when
g_task_propagate_*() is called, it’s cleared again. We need a new state
bit.

This method drops the last reference *it* owns to the GTask, but then
continues to call methods on the GTask. This wasn’t resulting in
failures because a ref in another thread kept the GTask alive, but
that’s quite dodgy.

The X-Flatpak-RenamedFrom key is used in .desktop files to identify past
names for the desktop file. It is defined to be a list of strings.
However, there was previously no correct way to retrieve a list of
strings from the GKeyFile wrapped by GDesktopAppInfo, short of
re-parsing the file with GKeyFile.
Note that doing something like:
g_strsplit (g_desktop_app_info_get_string (...), ";", -1)
is not correct: the raw value "a\;b;" represents the one-element list
["a;b"], but g_key_file_get_string() rejects the sequence "\;", and so
g_desktop_app_info_get_string() returns NULL in this case. (Of course, a
.desktop file with a semicolon in its name is a pathological case.)
Add g_desktop_app_info_get_string_list(), a trivial wrapper around
g_key_file_get_string_list(), similar to g_desktop_app_info_get_string()
and co.
The change from g_key_file_free() to g_key_file_unref() in the test is
needed because g_key_file_free() clears the contents of the keyfile.
This is fine for all the fields which are eagerly loaded and copied into
GDesktopAppInfo, but not when we want to access arbitrary stuff from the
keyfile.
This avoids the convenience library being treated as though it was
an installed static library (objects not included in the dependent
static library, and convenience library being listed in the pkg-config
metadata), both of which would make static linking impossible.
This is a workaround for meson not having
https://github.com/mesonbuild/meson/pull/3939 merged yet.
