OpenPalm port to RTEMS

I have spent a few days working on porting OpenPalm to RTEMS
and now have most of the porting layer written.  There are a
number of things left to deal with and this is an invitation
for help. Some of the issues left are:

+ The OpenPalm framebuffer interface for RTEMS is a stub.
+ alloca() is undefined.
+ settimeofday() needs to be implemented in RTEMS.
+ The use of POSIX condition variables in the thread interface
  has some tinkering left to do in regard to timeouts and
  the use of pthread_cond_wait().
+ no testing yet.

Overall, I think the port is actually in pretty good shape and
just needs some gently love to push it along.  With the holidays 
coming up, I won't be able to spend more time on it.

OpenPalm Folks: I don't know your policy on snapshots but the
port is far enough along where it could be merged and work done
on OpenPalm snapshots.  I do not want OpenPalm-RTEMS to be an
odd branch.
