496fba81c8 A shared space multi-threaded example application presenting the use of the 
thread library. It also exemplifies how a new sample application can be added.

9a8e1fa437 A few things needed in the destroy code paths of a thread are added. 
The first one is related to resource recycling. The parent which is waiting its
child to exit did not delete its ktcb. Now, it deletes.

The second one is related to self destroy. The added code wakes up all the
waiters before it exits.

7387d336cc Thread waiting is fixed. 
In the former case, when a child was exiting there was a risk of being preempted while it
was also taken away from the runqueue. In this situatuion, it may not have had
the chance of waking up the parent in case if it waits for the child to exit.

This was also true for suspend & resume so they were patched also.

682c62f8bb A fix and a helper macro for the thread library. 
The fix solves the problem of giving the last slice from a pool.

The helper macro makes utcb space creation easy for the user because we have to
consider a few things like alignment and total allocated space.

7fb923cd35 A workaround for an unmatched locker-unlocker mutex problem. 
If sleepers on a mutex were more than one, only one of them was woken up. This
caused the other ones to sleep forever. Now, there is not any facility to check
if there are still sleepers on the kernel space when a thread is about to unlock
a mutex. To workaround this problem, we started waking up all the threads
instead of one. This brings another problem called thundering herd but also
provides random fairness which gives more oppurtunity to a higher priority
thread to get the lock.

7a78483904 Final touches to configure all capabilities 
Standard capabilities are provided. They can be optionally disabled.
Also 4 custom capabilities are provided. They can be optionally
enabled and configured to different types/targets. Particularly
inter-container ipc will be done by these capabilities.

69ad9d929a Added precise capability targeting 
IPC capability targets current container, current pager's space,
another container, or another container's pager.

Any other capability (e.g. thread_control) targets current container
or pager's space.
