gtype: fix a no-op assertion

g_type_class_add_private() was doing

    g_assert (node->data->instance.private_size <= 0xffff);

but that field is a guint16, so the check was a no-op. (Noticed by
clang, but not gcc for some reason.) Fix it to do the math in a gssize
variable and do the bounds checking there before updating the struct
field.

fix atomic ops detection

AC_TRY_LINK should be used instead of AC_TRY_COMPILE because the code
will compile everywhere, either producing ``atomic'' code, or an
external reference to __sync_bool_compare_and_swap.

gsocket: make GSocketSource trigger on G_IO_NVAL

Getting G_IO_NVAL probably indicates bugs/race conditions in the
calling code, but if GSocket just ignores it, it will get stuck in an
infinite loop.

gdatetime: Extend the '%z' timezone format

Implement gnulib strftime extensions for the '%z' numeric timezone
format. These are also supported and documented by GNU date(1):

%z     +hhmm numeric time zone (e.g., -0400)

%:z    +hh:mm numeric time zone (e.g., -04:00)

%::z   +hh:mm:ss numeric time zone (e.g., -04:00:00)

%:::z  numeric time zone with : to necessary precision (e.g., -04, +05:30)

gsocket: Fix g_socket_get_available_bytes() on Windows and OS X

On Windows and OS X, FIONREAD on a UDP socket gets the total number of
bytes available, not the number of bytes available in the next packet,
which is the more useful number (and how the function always behaved
on Linux).

On OS X, fix this by using SO_NREAD. On Windows, fix this by doing a
MSG_PEEK recv() into a giant buffer, since there is apparently no
other way to get the information.

gio/tests/socket: fix warning building on win32

setsockopt() has a broken prototype on win32. Fix this by just using
g_socket_set_option() instead.
gmessages: fix g_test_expect_message() with NULL domains

Allow passing a NULL domain to g_test_expect_message(), and more
importantly, don't crash if a message with a NULL domain gets logged
while there is an expected message.

Visual C++ Builds: Fix "install" Projects

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.
