Ensure that all the old log handler documentation includes
cross-references to a new section about how to enable structured logging
(tl;dr: #define G_LOG_USE_STRUCTURED).
https://bugzilla.gnome.org/show_bug.cgi?id=769785
Give some example log domains, and recommend that G_MESSAGES_DEBUG is
used universally as the way to enable debug output (rather than having a
separate environment variable per library).
https://bugzilla.gnome.org/show_bug.cgi?id=682794
It’s effectively deprecated if G_LOG_USE_STRUCTURED is defined, or if
the structured logging API is used directly. See the documentation for
rationale.

g_log_writer_is_journald() works out whether the process’ stderr or
stdout are redirected to journald. While the default writer function
uses this in conjunction with g_log_writer_journald(), that does not
always have to be the case — other writer functions might want to always
write to the journal, and never write to stderr (for example).
Consequently, automatically open the journal socket in
writer_journald(), rather than is_journald().

The C spec leaves conditional evaluation inside a macro expansion as
undefined behaviour. This means we cannot use constructs like:
GOBJECT_IF_DEBUG(OBJECTS, {
...
#ifdef BLAH
...
#endif
...});
Because compilers are entirely justified to ignore the conditional, or,
like in the case of MSVC, error out.

GDatagramBased allows connection-oriented and connection-less sockets,
but does not allow stream-based sockets (because it’s datagram-based).
So it supports SCTP and UDP, but not TCP.
Clarify that in the documentation, and people sometimes confuse
connection-oriented with stream-based, due to the prevalence of TCP.
This is causing trouble with flatpaks because the org.gnome.Platform
runtime does not bundle libmount, while the org.gnome.Sdk does it.
As this probably requires a change in the freedesktop.org Yocto base,
we disable this support by default for now as a temporary measure
until it can be properly reviewed by someone who knows those bits
better, probably Alex Larsson.

Use mnt_context_get_mtab instead of using mnt_context_get_table(), since
that's the recommended way of accessing mtab/mountinfo information, and
also because that way the (struct libmnt_table *) will get automatically
deallocated when calling mnt_free_context()

journald is a part of systemd which is Linux-only at this time, so only
compile the journald items on Linux only, and just return FALSE for
g_log_writer_is_journald() and G_LOG_WRITER_UNHANDLED for
g_log_writer_journald() on non-Linux.

Talk to the journal ourselves using sendmsg() instead of linking
against libsystemd for sd_journal_sendv(). At the same time, we
can also avoid excessive copying.
The motivation for dropping the dependency is that we can
then use structured logging e.g. in a flatpak sandbox where
libsystemd may not be present in the runtime.
The code here is inspired by similar code in libvirt.
Currently the docs for GChecksumType are simpy annotated
with 'Since 2.16' which is when GChecksumType was first
introduced. No mention is made of the fact that the
G_CHECKSUM_SHA512 constant was only added much later
in 2.36.
