release of GLib 2.25.11

Hi again,

It's been a couple of weeks, so it's time for another GLib release.  I'm
feeling extra creative, so let's call this one "2.25.11".

You can find it in the usual place:

  http://download.gnome.org/sources/glib/2.25/

Make sure to check those checksums!

f83cdc74b9a0a8514c496c68f3d4887d38d5de64ffb9b8cdede7e94bb140b16f  glib-2.25.11.tar.bz2
28cbc02036a7f232f23ce56feda3e10bd74fe676902b305bf2a15a8b2c7c9225  glib-2.25.11.tar.gz

This is a development release leading to GLib 2.26.

Note that there have been some more ABI breaks this time around.  You
will want to install a new GTK+ and dconf to go with this release of
glib (both of which will be along shortly).  See the NEWS section below.

We're going to try to slow it down with the API breaking, but probably
we are not done yet.  Particularly, some changes to GApplication are
being considered for the next release.

Notes:

 * This is unstable development release. While it has had
  a bit of testing, there are certainly plenty of bugs
  remaining to be found. This release should not be used
  in production.

 * Installing this version will overwrite your existing
  copy of GLib 2.24. If you have problems, you'll need
  to reinstall GLib 2.24.

 * GLib 2.26 will be source and binary compatible with
  the GLib 2.24 series; however, the new API additions
  in GLib 2.25.x are not yet finalized, so there may
  be incompatibilities between this release and the final
  2.26 release.

 * Bugs should be reported to http://bugzilla.gnome.org.


About GLib
==========

GLib is the low-level core library that forms the basis for projects
such as GTK+ and GNOME. It provides data structure handling for C,
portability wrappers, and interfaces for such runtime functionality as
an event loop, threads, dynamic loading, and an object system.

More information about GLib is available at:

 http://www.gtk.org/

An installation guide for the GTK+ libraries, including GLib, can
be found at:

 http://developer.gnome.org/doc/API/2.0/gtk/gtk-building.html


Overview of Changes from GLib 2.25.10 to GLib 2.25.11
=====================================================

+-------------------------------------------------------------------+
| WARNING: There have been minor API changes in GDBus and GVariant. |
| These API changes will not affect many users, but they do require |
| a new version of GTK+ to be installed.                            |
+-------------------------------------------------------------------+

Build:
  - add a --disable-Bsymbolic configure flag to disable linking with
    -Bsymbolic-functions
  - this release sees the complete removal of the old 'g*alias' hacks
  - honour the NOCONFIGURE environment variable from autogen.sh
  - use proper feature test macros for isnan
  - use pkg-config to check for zlib
  - add ACLOCAL_AMFLAGS to Makefile.am

GDBus:
  - hide Class and instance structures for all GDBus types except
    GDBusProxy.  This breaks API by preventing subclassing, but probably
    nobody was doing that.
  - add new GDBusConnection call to support flushing all pending
    outgoing messages
  - change the register_object API to add a reference to the
    GDBusInterfaceInfo object so the caller need not keep it alive
    themselves
  - don't rewrite the serial number when sending messages that already
    have a serial number
  - better error checking for DBUS_SESSION_BUS_ADDRESS environment
    variable
  - switch to g_parse_debug_string for G_DBUS_DEBUG and add a lot of new
    flags
  - add support for temporarily freezing a freshly created
    GDBusConnection.  Do this until after the ::new-connection signal
    has finished running on GDBus services.
  - never require non-closed connections (the user is incapable of doing
    this due to the obvious race)
  - remove weird/misleading redundant check on NameOwnerChanged signal
  - emit GDBusProxy::g-properties-changed on NameOwnerChanged

GVariant:
  - the 'g_variant_{new,get}_byte_array' APIs have been removed
  - g_variant_{new,get,dup}_bytestring has been added, with different
    arguments and different behaviour
  - g_variant_{new,get,dup}_bytestring_array has been added, doing
    essentially the same thing as the 'strv' functions, but with byte
    strings instead of utf8 strings
  - G_VARIANT_TYPE_BYTESTRING ('ay'), BYTESTRING_ARRAY ('aay') and
    STRING_ARRAY ('as') constants have been added
  - the undocumented behaviour that g_variant_get_strv() deserialised
    arrays of object paths or signature strings has been dropped
  - additional varargs support for converting bytestrings or bytestring
    arrays with ^ay ^aay ^&ay and ^a&ay
  - improved gobject-introspection annotation
  - fix a problem with GBuffer calling g_slice_free for the wrong type
  - fix leaks in the type inferencing code of the parser

GSettings:
  - improved documentation
  - updated schema XML DTD, now xincluded into the docs
  - added support for schemas that extend other schemas (using the
    'extends=' attribute).  Values of keys in the base schema can be
    overridden using <override>.
  - added theoretical support for lists (using the 'list-of=' attribute)
  - lots of new tests
  - add support for flags (implemented similarly to enums)
  - add support for generating .enums.xml files to gsettings.m4:
      gsettings_ENUM_NAMESPACE = org.example.myapp
      gsettings_ENUM_FILES = ../path/to/*.h
    will generate org.example.myapp.enums.xml with mappings for all
    enums and flags in the specified .h files.
  - warn with g_message() if the 'memory' backend is used by default
    (ie: because no other GSettings backends are installed)
  - fix get_property() for GSettings::schema
  - command line tool: fix a bug that prevented non-basic values from
    being set due to a premature free
  - command line tool: bash completion support
  - chain up in _finalize
  - add a new g_settings_get_mapped API to read settings that require
    post-processing
  - retry with the translated or schema default value if the
    GSettingsBindGetMapping function fails
  - schema compiler: never fail due to empty schema directories (but
    warn)
  - peek rather than ref/unref the GEnumClass in the mapping function
  - schema compiler: compile *.enums.xml before *.gschemas.xml to ensure
    that we have all the enums that the schemas may reference
  - schema compiler: improve accuracy of line numbers in error reports
  - fix crashes in the keyfile backend caused by invalid group names in
    the keyfile

Other:
  - always intern GBinding prop names
  - base64: remove asserts preventing conversion of empty strings
  - document NULL special-cases for GValueArray
  - GNode docs improvements
  - improve detection of 'system internal' mounts
  - fix leaks in the inotify GFileMonitor implementation
  - annotate all custom GIO GSources to improve debugging (e.g. using
    SystemTap)

Tests:
  - Turn on glibc malloc checking features for make check
  - improvements for GSettings tests, plus new tests
  - improved tests for GKeyfile
  - new tests for GDir, GSList, GSList, GAppLaunchContext,
    CharsetConverter, GIcon, ...
  - move some tests to GTester (tree tests, uri tests)
  - generally, really an awful lot of new tests
  - don't try to allocate 2gigs of memory anymore for the array test

 552363 g_value_array_{insert,prepend,append}'s special cases for NULL
 561248 Improve return value description from g_node_prev/next_sibling()

 576833 g_sprintf add a reference to g_strdup_printf
 576854 g_strconcat() documentation should provide a hint about bad l10n
