With this patch it is fine to call g_hash_table_lookup and
g_hash_table_remove from destroy notification functions. Before
this could lead to an infinitie loop if g_hash_table_remove_all
was used.

Add a "posixly correct" mode to GOption to stop parsing arguments as
soon as the first non-option argument is encountered.
We determine the default value on the basis of duplicating the behaviour
of the system getopt() implementation (which we directly check the
behaviour of at runtime). On GNU systems this allows the user to modify
our behaviour using POSIXLY_CORRECT.
The user can change the value by g_option_context_set_strict_posix(),
which might be useful for some usecases of GOptionContext (as mentioned
in the doc string of this new function).

Commit e24e89b accidentally ironically introduced a typo when replacing
the code with symbolic contents. Specifically, "Added Associations" was
replaced with "Default Applications" when reading defaults.list, giving
a warning about the file containing a "Default Applications" group.
If this was intended, it should have not been lumped in with a cleanup.
Add GOBJECT_DEBUG=instance-count which enables internal accounting
of the number of instances of each GType, and g_type_get_instance_count()
to retrieve the result.

g_get_monotonic_time() and g_get_real_time() now always use different
clocks, so we cannot avoid correcting for their offset. Fixes failure
to time out on Mac OS X.

Internal allocation size (array->alloc) was being kept to 0 when a new
GByteArray was created from an already existing heap-allocated buffer.
Among other things, this was making g_byte_array_set_size() fully clear all
the buffer contents (not just the newly allocated memory) when
G_DEBUG=gc-friendly was being used...
if (G_UNLIKELY (g_mem_gc_friendly))
memset (array->data + array->alloc, 0, want_alloc - array->alloc);

This patch changes the behavior of the following functions:
g_tls_certificate_new_from_pem
g_tls_certificate_new_from_file
g_tls_certificate_new_from_files
If more than one certificate is found it will try to load the chain.
It is assumed that the chain will be in the right order (top-level
certificate will be the last one in the file). If the chain cannot be
verified, the first certificate in the file will be returned as before.

If a GSource is created, *not* attached to a GMainContext, and then has
child sources added, dropping the last reference to the parent GSource
will leak its references to its child sources. Currently, child sources
are only unreffed when g_source_destroy() is called on the parent.

g_thread_pool_push() only returns an error if it fails to spawn a new
thread. However, it unconditionally adds the task to its worker queue,
so:
• if _any_ threads exist in the pool, the task will eventually be
handled; and
• if _no_ threads exist in the pool, the task will be handled if one
is eventually successfully spawned.
If no more threads are ever spawned, the process probably has bigger
problems than a single GTask which is taking forever to complete.

Step up thread safety on g_source_set_name() to the same standard as all
other GSource functions: after we are attached to a main context, this
function should be threadsafe.

Document that one must not use the "by id" source APIs with non-existent
IDs. The real justification behind this restriction is that the reuse
of source ids makes it unsafe to call these functions unless you're
absolutely sure that the source exists and it belongs to you. If you
call one of these functions on a source that may already have been
removed then you run the risk of finding someone else's source (with
your reused id).
This also bails us out of a slightly tricky situation with respect to
the threadsafety of g_main_context_find_source_by_id(). The fact that
this function doesn't return a reference implies that its return value
cannot be safely accessed unless we already know for sure that a
reference is being held elsewhere (by example, by the main context
itself if we know that the source has not been removed). The function
itself, however, performs an access to the value, which could result in
a crash.
If we mandate that it is only valid to call this function on
known-to-exist source IDs then we dodge this problem.

This confused me for a while, because it isn't the same as D-Bus.
Like GVariant, the D-Bus serialization needs an out-of-band
endianness and type indicator, but unlike GVariant, serialized
D-Bus objects encapsulate their own length (often by starting with
a byte-count). This does come at some redundancy cost, so I can see
why the more efficient GVariant format does this the way it does;
but it's a difference between D-Bus and GVariant that seems worth
calling out.
It's also relevant for the designers of file or message-framing
formats: with D-Bus serialization it would be feasible to say "the file
starts with a little-endian D-Bus variant, followed by...",
but in GVariant you wouldn't be able to deserialize the variant
unless you either assume that it extends to end-of-file, or have
an explicit length.
