g_cancellable_disconnect will wait until any pending "cancelled"
handlers finish. This is useful because disconnecting a handler can have the
side-effect of freeing data that the cancelled handler may rely on.
Unfortunately, the code used to enforce this synchronization between
"cancelled" handlers and g_cancellable_disconnect will also cause
deadlock if the cancelled handler itself calls g_cancellable_disconect.
Obviously, if g_cancellable_disconnect is explicitly called by a "cancelled"
handler, then the "cancelled" handler is shouldering the responsibility
of not using any data that may be freed by disconnection.
Also, g_cancellable_disconnect can be called in unexpected places by
lower layers in the code (for instance as a result of g_source_destroy).
In practice, this means it's easy for deadlocks to inadvertently crop
up when using "cancelled" handlers.
For these reasons, it would be good to fix the deadlock.
This commit prevents the deadlock by allowing foregoing synchronization,
if a pending "cancelled" handler is in the same thread as the
g_cancellabale_disconnnect call.

This commit adds a test to ensure that during a signal emission, if
a signal handler gets disconnected, it won't be run, even if it would
have run before the disconnection.
Apple's GCC compilers cannot deal well with 64-bit pointers in
transparent unions on ppc64, so compilation of
_G_DEFINE_BOXED_TYPE_BEGIN was failing. Fortunately glib already
provides a fallback for compilers that can't deal with it; this adds
this specific case to the check.

In the real_..._async wrapper for GFile.measure_disk_usage, skip the
wrapping of the progress callback in the case that the user gave a NULL
callback to the async function. This is a performance improvement
because the sync version won't have to do continuous sampling of the
clock to issue a call to the wrapper which will then do nothing.
Unfortunately, I made this simplifying assumption when writing the
wrapper, but forgot to actually implement it when making the sync call.
As a result, the wrapper is still called, and invokes the NULL callback,
causing a segfault.
Make sure we pass NULL if the user's callback was NULL.

Make use of __wgetmainargs() on Windows so that we can get wide char
versions of the argv's that are passed in when this test program is being
invoked. This is necessary as one might enter non-ASCII, such as
CJK characters filenames and/or directories to run the test program
against, so that we can process the name(s) and pass the proper
UTF-8-encoded name(s) of the files/directories that is being tested.

It turns out that although dirent is available on mingw32 (where the
code was originally tested), it is not usable from MSVC.
Avoid portability problems by just using GDir.
Also, be careful about ensuring that we utf8-format filenames in our
error messages, and leave out the "file://" component since the strings
we're displaying are not URIs (and we don't want to make them URIs since
the extra escaping would reduce legibility).

Add a simple UNIX-only API that is used to create a GDir object from a
DIR* that is aquired using opendir() or fdopendir().
This makes it possible to use GDir with openat(), which in turn will
allow use of GDir in the existing GLocalFile implementation of
g_file_measure_disk_usage(), avoiding the current MSVC compatibility
problems there.
Also add an API similar to g_dir_open(), but without the GError handling
(since we want to create a better error message from inside of
glocalfile.c).

Virtaal installs a mime package for various .po-like file formats, one
of which has the extension .txt. This causes GLib to report ".txt"
files still as "text/plain" but no longer with complete certainty.
The result is that asserting !uncertain during the testsuite causes the
test to fail if Virtaal happens to be installed.
Remove this assertion.
We're testing for particular error messages, so we need to set to a C
locale to make sure we get the untranslated version.
Previously, this test set the LANG environment variable, but that's not
good enough if LANGUAGE is also set. The only way to ensure that
LANGUAGE is ignored is to disable l10n with LC_ALL=C.
Due to the split up of the property sheets, the install projects did not
have info on the Intermediate and Output Paths, which caused confusing
messages from Visual Studio to show up upon completing build+"install" and
closing Visual Studio on whether to reload the install project, at least on
Visual Studio 2008.
Include the property sheet which defines these properties to fix this.
