This is a combination of g_hash_table_lookup_extended() and
g_hash_table_steal(), so that users can combine the two to reduce code
and eliminate a pointless second hash table lookup by
g_hash_table_steal().

Getting the canonical filename is a relatively common
operation when dealing with symbolic links.
This commit exposes GLocalFile's implementation of a
filename canonicalizer function, with a few additions
to make it more useful for consumers of it.
Instead of always assuming g_get_current_dir(), the
exposed function allows passing it as an additional
parameter.
This will be used to fix the GTimeZone code to retrieve
the local timezone from a zoneinfo symlink.
(Tweaked by Philip Withnall <withnall@endlessm.com> to drop g_autofree
usage and add some additional tests.)

This is a non-trivial accessor which gets the identifier string used to
create the GTimeZone — unless the string passed to g_time_zone_new() was
invalid, in which case the identifier will be `UTC`.
Implementing this required reworking how timezone information was loaded
so that the tz->name is always set at the same time as tz->t_info, so
they are in sync. Previously, the tz->name was unconditionally set to
whatever was passed to g_time_zone_new(), and then not updated if the
tz->t_info was eventually set to the default UTC information.
This includes tests for the new g_time_zone_get_identifier() API, and
for the g_date_time_get_timezone() API added in the previous commit.

g_key_file_get_locale_string() returns a translated string from the
keyfile. In some cases, it may be useful to know the locale that that
string came from.
Add a new API, g_key_file_get_locale_for_key(), that returns the locale
of the string.
Include tests.
(Modified by Philip Withnall to rename the API and fix some minor review
issues. Squash in a separate test case commit.)

It's a very common pattern to see code that looks like this in
dispose() or finalize() implementations:
if (priv->source_id > 0)
{
g_source_remove (priv->source_id);
priv->source_id = 0;
}
This API allows to accomplish the same goal with a single line:
g_clear_handle_id (&priv->source_id, (GClearHandleFunc) g_source_remove);
Thanks to Emmanuele Bassi <ebassi@gnome.org> for making the patch
generic.

This supports a subset of ISO 8601 since that is a commonly used standard for
storing date and time information. We support only ISO 8601 strings that contain
full date and time information as this would otherwise not map to GDateTime.
This subset includes all of RFC 3339 which is commonly used on the Internet and
the week and ordinal day formats as these are supported in the GDateTime APIs.
(Minor modification by Philip Withnall to change API versions from 2.54
to 2.56.)

Very often when we want to convert a string to number, we assume that
the string contains only a number. We have g_ascii_strto* family of
functions to do the conversion but they are awkward to use - one has
to check if errno is zero, end_ptr is not NULL and *end_ptr points to
the terminating nul and then do the bounds checking. Many projects
need this kind of functionality, so it gets reimplemented all the
time.
This commit adds some replacement functions that convert a string to a
signed or unsigned number that also follows the usual way of error
reporting - returning FALSE on failure and filling an error output
parameter.
The macro could be used at initialization time to avoid having an
unitialized builder, especially with g_auto variables.
The macro tries to be a bit more type-safe by making sure that the
variant_type parameter is actually "const GVariantType
*". Unfortunately I have no idea how to make it possible to also pass
a "const gchar *" parameter without warning.

This makes it easier to use GKeyFile from language bindings, and makes
the API more consistent and modern with the new data type available in
GLib.
https://bugzilla.gnome.org/show_bug.cgi?id=767880
Add some helpers for builds-checked unsigned integer arithmetic to GLib.
These will be based on compiler intrinsics where they are available,
falling back to standard manual checks otherwise.
The fallback case needs to be implemented as a function (which we do
inline) because we cannot rely on statement expressions. We also
implement the intrinsics case as an inline in order to avoid people
accidentally writing non-portable code which depends on static
evaluation of the builtin.
For now there is only support for addition and multiplication for guint,
guint64 and gsize. It may make sense to add support for subtraction or
for the signed equivalents of those types in the future if we find a use
for that.

Fix a few typical problems, and also stop wrapping the inline definition
of g_steal_pointer in parens, since it is not necessary and it confuses
gtk-doc.
Add g_auto() and g_autoptr() as helpers for declaring variables with
automatic cleanup.
Add some macros to help types define cleanup functions for themselves.
Going forward it will be an expectation that people use this macro when
creating a new type, even if they do not intend to use the auto-cleanup
functionality for themselves.
These new macros only work on GCC and clang, which is why we resisted
adding them for so long. There exist many people who are only
interested in writing programs for these compilers, however, and a
similar API in libgsystem has proven to be extremely popular, so let's
expose this functionality to an even wider audience.
We ignore deprecation warnings when emitting the free functions, which
seems suspicious. The reason that we do this is not because we want to
call deprecated functions, but just the opposite: sometimes the free
function will be an _unref() function that is only AVAILABLE_IN newer
versions, and these warnings are also implemented as deprecation
warnings.

- GSubprocessLauncher exists since 2.40, not 2.36
- more logical order for g_markup functions
- fix short description of GMarkup
- GMarkupParser: specify that some parameters are NULL-terminated.
- g_string_new (NULL); is possible.
- other trivial fixes.

Add a new function, g_str_to_ascii() that does locale-dependent ASCII
transliteration of UTF-8 strings.
This function works off of an internal database. We get the data out of
the localedata shipped with glibc, which seems to be just about the best
source of locale-sensitive transliteration information available
anywhere.
We include a update script with this commit that's not used by anything
at all -- it will just sit in git. It is intended to be run manually
from time to time.
