Any file handle created with FLAG_OVERLAPPED must have
ReadFile()/WriteFile() called with an OVERLAPPED structure.
Failing to do so will give unspecified results, invalid read/write or
corruption.
Without FLAG_OVERLAPPED, it is not possible to read and write
concurrently, even with two seperate threads, created by 2 input and
output gio streams. Also, only with FLAG_OVERLAPPED may an IO
operation be asynchronous and thus be cancellable.
We may want to call ReOpenFile() to make sure the FLAG is set, but
this API is only available since Vista+.
According to MSDN doc, adding the OVERLAPPED argument for IO operation
on handles without FLAG_OVERLAPPED is allowed, and indeed the existing
test still passes.
v2:
- update GetLastError() after _g_win32_overlap_wait_result ()
- split the unrelated ERROR_MORE_DATA handling

g_cancellable_create_source() returns a GSource that triggers when its
corresponding GCancellable is cancelled. This can be used with
g_source_add_child_source() to add cancellability to a source.
Port gasynchelper's FDSource to use this rather than doing its own
cancellable handling, and also fix up its callback argument order to
be more normal.
https://bugzilla.gnome.org/show_bug.cgi?id=634239
the FdSource was calling g_cancellable_disconnect while holding the
main context lock, which is bad news if the ::cancelled handler is
trying to get that lock to wake up the mainloop...

* 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.
