Parts of the `dbus-appinfo` test need support for converting an FD to a
path, and Hurd doesn’t currently allow that (see
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/4396#note_2279923).
Since there’s no fix for that visible in the medium term (new kernel
APIs will need to be added), skip parts of the `dbus-appinfo` test which
require that functionality for now.
This prevents the whole test from failing, and means we can usefully get
results from the parts of it which don’t depend on converting FDs to
paths.

A settings schema that extends another schema should return TRUE for
all keys that are present in the extended schema. The list of keys
returned by list_keys() already includes these,
so it makes sense to include them in has_key().

Sender can be NULL if not specified by the caller, e.g. on peer-to-peer
connections.
Interface name can be NULL on method calls if it was not specified by
the sender.
Both is explicitly allowed by the DBus specification.
This could potentially eventually become a public GLib API, but there
doesn’t seem to be a huge need for it right now (e.g. this file contains
the only use of `/proc/self/fd/%d` in GLib), so let’s keep it private
for now and avoid committing to API stability just yet.
This gives time for other platforms to add their platform-specific
implementations for it too, if they need. I’ve added a couple of
pointers to what I *think* the right APIs might be, from my research,
but I have not prototyped those implementations.

When a conversion is finished, the code would return 0 from its write
vfunc. This is disallowed by the API of g_output_stream_write() and
causes g_output_stream_splice() as used by g_converter_convert_bytes()
to turn into an infinite loop.
Instead, raise a G_IO_ERROR_MESSAGE_TOO_LARGE error so that the calling
code can decide how to deal with it.
Testcase included.
Closes#3532
This fixes commit aac56f1618 — I missed
this while reviewing it, but the unit tests were partially changed to
call the new APIs, without being fully changed. This caused the build to
succeed on Linux, but fail on macOS due to using a deprecated API.
Actually, a better approach for the unit tests would be to consistently
call the *old* APIs, as they all immediately call the new APIs. Then we
get coverage of both old and new for free, at the cost of putting
`G_GNUC_BEGIN_IGNORE_DEPRECATIONS` at the top of the test file.

UnixMountEntry: Deprecate g_unix_mount_* API in favor of g_unix_mount_entry_* API for GUnixMountEntry methods
Closes#3492
See merge request GNOME/glib!4337
This issue arises because the g_unix_mount_* naming convention does not match
the GUnixMountEntry instance type, confusing the introspection generator.
To resolve this, we are deprecating the g_unix_mount_* API functions that take
a GUnixMountEntry parameter and introducing equivalent g_unix_mount_entry_*
functions that correctly associate with the GUnixMountEntry instance. This change
ensures that introspection data correctly treats these as instance methods and
that documentation reflects proper ownership of returned data.
(Some minor tweaks by Philip Withnall.)

It appears not to work, and nobody interested in FreeBSD has picked it
up to investigate yet.
Rather than have a completely broken implementation of
`g_file_query_exists()` on FreeBSD, let’s settle for using the old one.
It’s slightly slower than the new one, but has worked fine for people
for years.
This essentially reverts commit 65ad41d8a4
on FreeBSD. This commit can be reverted when a FreeBSD person
investigates what’s going wrong with the `faccessat()`-based
implementation.

Commit 760a6f647 rearranged how the lengths are calculated for the test
data and added `escape_data_string()` so they could be printed safely.
Unfortunately there was a miscount in the length of the first test
vector in `test_read_upto()`: there are 31 bytes in the string literal,
plus one nul terminator which is added by the compiler. The quoted
string length was 32 bytes. This should be fine (explicitly including
the nul delimiter), but then `escape_data_string()` adds another byte to
the length because it assumes the nul delimiter has *not* been included
in the count.
Changing the string length from 32 to 31 breaks the tests, as the final
component of the data is then the wrong length, so add an additional
explicit nul byte to the string literal so that it matches the length.

This is a follow up to commit e7e5ddd2a. oss-fuzz found a case where
performance was pathologically bad with a long `stop_chars` string.
Since our inner loop in that case was iterating over `stop_chars` and
comparing each of them to `buffer[i]`, we can use `memchr()` the
opposite way round to in commit e7e5ddd2a to speed that up, using
`buffer[i]` as the needle in a `stop_chars` haystack.
From some brief testing, this doesn’t impact on the performance of a
more normal use case of having a short (<10 bytes long) `stop_chars`. I
was slightly concerned that the function call overhead of calling out to
`memchr()` would have an impact there, but apparently not.

For historical reasons, pid_t & mode_t are defined as long instead
of int for 32-bit processes in the Solaris headers, and even though
they are the same size, gcc issues -Wformat headers if you try to
print them with "%d" and "%u" instead of "%ld" & "%lu".

The method was correctly returning an error from
`g_data_input_stream_read_line_utf8()` if the line contained invalid
UTF-8, but it wasn’t correctly setting the returned line length to 0.
This could have caused problems if callers were basing subsequent logic
on the length and not the return value nullness or `GError`.

ip_mreqn.imr_ifindex is not used correctly by the XNU kernel, and
causes us to bind to the default interface; so fallback to ip_mreq
