b85649c47b basic test cases for kill() and alarm(). 
kill() in particular needs more test cases for full coverage.  The search
for a thread interested in this signal has a lot of paths.

ea1a5bef17 first attempt at adding algorithm to select the thread which will 
receive a process-directed signal.

699fe08a25 Added test case which blocks a signal, sees what signals are pending, sends 
that same signal to the executing thread, sees what is pending, then unblocks
that signal so the handler can execute.

c8f5ab5d2e tested blocking a signal, sending it to self, then unblocking it. 
make minimum stack size for posix threads double that of the cpu's minimum
requirement.

fb39f191da modified to test pthread_kill() to self and pthread_kill() to a blocked 
thread.  nanosleep() can be interrupted and return the time remaining.

12aeff91fe Interruptible by signals state was added to the STATES_BLOCKED set. It 
can not be part of the locally blocked set since it by itself does not
indicate that the thread is blocked.

98ed15e30f Basic signal functionality appears to work. pthread_kill() can successfully 
send signals to the current thread or to another blocked thread.  nanosleep()
can be interrupted by a signal and return the time remaining.

Post switch extension added to dispatch posix signal handlers.

This test does a basic checkout of signals with a thread-directed signal
(pthread_kill()) used to interrupt a nanosleep().

should be correct for other apis as well.

missing page numbers added on some references.

0207c55825 Made the implementation of pthread_equal conditional on RTEMS_DEBUG. If 
RTEMS is built for debug, then every possible effort is made to validate
the two ids.  Otherwise, a simple comparison is performed.
