If threads are available we always enable threads in gobject, which
means all gio/gobject code can enable the unconditional thread calls.
This is a minor optimization since we avoid a bunch of unnecessary
is-threads-enabled checks.

Since gobject now initialized threads unconditionally if threads are
available it makes no sense to have each thread operation
conditionally check if threads are enables, so allow this to be avoided.

We now allow g_thread_init(NULL) to be called after other glib calls (with
some minor limitations). This is mainly a documentation change as this
really was already possible.
We also allow g_thread_init() to be called multiple times. Only the
first call actually initializes the threading system, further calls
are ignored (but print a warning if the argument is not NULL).

Adds an optional query method to giomodules which should return all
possible extension points the module may implement.
Then we add a new call g_io_modules_scan_all_in_directory() similar to
g_io_modules_load_all_in_directory() that doesn't return all loaded
modules, thus allowing lazy loading.
In g_io_modules_scan_all_in_directory we look for an optional
giomodule.cache file and use the information in that to avoid
loading modules until they are needed for an extension point.
In the deserialise function, GUnixFDMessage was comparing 'level' to
both SOL_SOCKET and SCM_RIGHTS. It is correct to compare 'type' to
SCM_RIGHTS. The code passed tests only because:
1) it's a "should always be OK" double-check
2) SOL_SOCKET and SCM_RIGHTS, by chance, both have the value '1' on
Linux systems.
Crash interception/debugging systems like Apport or ABRT capture core dumps for
later crash analysis. However, if a program exits with an assertion failure,
the core dump is not useful since the assertion message is only printed to
stderr.
glibc recently got a patch which stores the message of assert() into the
__abort_msg global variable.
(http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=48dcd0ba)
That works fine for programs which actually use the standard C assert() macro.
This patch adds the same functionality for glib's assertion tests. If we are
building against a glibc which already has __abort_msg (2.11 and later, or
backported above git commit), use that, otherwise put it into our own field
__glib_assert_msg.
Usage:
$ cat test.c
#include <glib.h>
int main() {
g_assert(1 < 0);
return 0;
}
$ ./test
**ERROR:test.c:5:main: assertion failed: (1 < 0)
Aborted (Core dumped)
$ gdb --batch --ex 'print (char*) __abort_msg' ./test core
[...]
$1 = 0x93bf028 "ERROR:test.c:5:main: assertion failed: (1 < 0)"
