[Xenomai-core] Xenomai v2.2-rc3

[Philippe Gerum <rpm@xenomai.org>]

Ok, five weeks is far too long between release candidates and we'll
try to shorten that, but still, the number of issues closed by -rc3 is
worth the delay. Significant POSIX skin updates, KGDB support merged
for x86, and another ARM port, this one over the iMX21, are among the
goodies. Here is the short log:

	unsafe unloads. Add a regular syscall table for handling
	internal nucleus syscalls. Add per-process cleanup handlers.

	* vxworks: Conformance fixes.

	Add support for user-space mutex and condition variable
	attributes. Cleanup per-process objects on process
	termination. Add support for the SCHED_NORMAL policy.

	* testsuite: Add context switch unit test.
