Giacomo Tesio e0e45fba5a kernel: removed unreachable code in fault (CID: 155701) 
If the user process does not have a segment holding the required addr
the fault function return early.

Giacomo Tesio 0b8a66f877 kernel: umem: fix img_get macro 
The img_get macro used to subtract 1 to the argument provided before
computing the porinter to the image. I can't remember why it did so.

However the expression was wrong.

Coverity found the issue:

	Operands don't affect result (CONSTANT_EXPRESSION_RESULT)
	CID:	155616, 155606, 155598, 155597, 155596, 155587,
		155580, 155578, 155577, 155576, 155568, 155566

Simply removing the subtraction seems the obvious fix.

- removed old code
- deep refactor of awake syscall
- removed MCACHE support for mount
- fix libc's setjmp/longjmp

Giacomo Tesio 1bc08b7631 kernel: rendezvous(~0, ...) unconditionally blocks 
This commit introduce a special rendezvous point at (void*)~0 that
cannot be reached by any process, since it's not added to the
rendezvous group.

This turns the rendezvous syscall to a cheap way to block until
either a note or a wakeup from awake(2) occurs.

This new feature is used in libc's sleep: the test qa/kern/fork_chain
has shown that using a stack address as rendezvous point is not safe enougth
for sleep, since two different process forked from the same function can
call sleep with the same base pointer. This lead the wakeup variable in
jehanne_sleep to have the same address on both process.

TODO add a test that show this behaviour in the old code.
