Add a convenient and race-free method of watching local files from the
GLib worker thread.
Without this, the race-free way to create a monitor that dispatches
events to the worker thread looked something like this:
- dispatch an idle to the worker thread
- from the idle, create the monitor and connect signals
- from the original thread, wait (on a cond?) until the worker thread
has finished setting up the monitor
- read the file that you were monitoring
which is just ridiculously complicated...
To use the new API:
monitor = g_local_file_monitor_new_in_worker ("/path/to/some/file",
G_FILE_MONITOR_NONE,
&error);
g_assert_no_error (error);
g_signal_connect (monitor, "changed", G_CALLBACK (callback), NULL);
g_local_file_monitor_start (monitor);
'callback' will run from the GLib worker thread.
This is the reason that the start() call was introduced in the previous
commit. The backends that don't use the start() call will have a very
thin race between creating the monitor and connecting the signal, but
hopefully they will be fixed soon.
These new APIs will be used (at least) from gdesktopappinfo to watch for
changes in the desktop file directories.

Stop abusing constructor() to do startup work, adding _start() calls
instead.
The backends themselves still use constructor() although a patch will be
following to also fix inotify.
The reason for using a separate start() call instead of constructed()
will become apparent in future commits.

Add a pair of new extension points: 'gio-nfs-file-monitor' and
'gio-nfs-directory-monitor'.
Add a check to GLocalFile when creating a file monitor. If the
requested file is in the user's home directory and the user has an NFS
home directory then attempt to use an implementation of one of the new
extension points. If we don't have any implementations then fall back
to the normal "local" monitors.

Get rid of the complicated default module detection code in
GLocalFileMonitor and GLocalDirectoryMonitor and use the new
_gio_module_get_default_type() function instead.
This change also adds the ability to override the default file monitor
via the GIO_USE_FILE_MONITOR environment variable in the same way as can
be done for GIO_USE_VFS.

don't dereference these function pointers when calling them since
that has no meaning at all.

* giomodule.c:
Make g_io_modules_load_all_in_directory not unuse
loaded modules so that users of it can do stuff
before unloading.
Init internal "module" types.
Initialize static prio and name for types so that
we don't have to load modules to get it.
* gnativevolumemonitor.h:
* gvolumemonitor.h:
Move is_supported to parent class so that
non-native monitors can avoid being initialized
too. (For instance GDaemonVolumeMonitor if we're
not using GDaemonVfs.)
* glocaldirectorymonitor.[ch]:
* glocalfilemonitor.[ch]:
* gunionvolumemonitor.c:
* gunixvolumemonitor.c:
* gvfs.c:
Find plugins using the static prio+name to
avoid unnecessarily loading the modules.

* gnativevolumemonitor.h:
* gunionvolumemonitor.c:
* gunixvolumemonitor.c:
Add is_supported() to GNativeVolumeMonitorClass so
that we can avoid having to create an object to see
if the backend is supported at runtime.
Also add name member and an env var to pick a specific
volume monitor backend.
* gmountprivate.h:
* glocalfile.c:
Add cancellable to _g_mount_get_for_mount_path()
* glocaldirectorymonitor.c:
* glocalfilemonitor.c:
Avoid loading and unloading modules while sorting.

* let g_warn_if_fail replace g_assert as discussed here:
http://mail.gnome.org/archives/gtk-devel-list/2007-October/msg00089.html
* fix bug #502498: Test framework assertion failures should follow
gcc error format.
* gmessages.h, gmessages.c: deprecated g_assert_warning() which is
unused now. removed g_assert*() definitions whcih are provided by
gtestutils.h now. added g_warn_if_reached() and g_warn_if_fail()
which are recommended as g_assert/g_assert_not_reached replacements
for non-test programs.
added g_warn_message() to implement g_warn_*() macros.
use emacs-next-error friendly formatting for file:line: for warnings.
* gtestutils.h, gtestutils.c: use emacs-next-error friendly formatting.
implement g_assert_not_reached() with g_assertion_message() and
g_assert() in terms of g_assertion_message_expr() so we'll be able to
provide assertion messages in test logs.
* gkeyfile.c, gbookmarkfile.c: changed g_assert*() to g_warn_if_fail()
or g_return_if_fail() where suitable.
* gio/: changed g_assert to g_warn_if_fail.

Make g_io_modules_ensure_loaded a private function and
don't pass in the dirname. This means we can do magic
directory finding in the win32 version.
Export the actual load-modules-in-directory code so that
gvfs can reuse that.
