Features:

The algorithms used for shmem_set_lock and shmem_clear_lock have
been improved for much better scaling. In a basic test of calls to set_lock
and clear_lock by a set of PEs all competing for the same lock, MPT
4.0.2 and MPT 4.0.3 perform about the same for a few nodes, but beyond
just a few, the time per PE for MPT 4.0.2 steadily increases with
the number of PEs whereas the time per PE for MPT 4.0.3 stays level.
At just 128 PEs, MPT 4.0.3 is about 4 times faster than MPT 4.0.2
and the difference keeps increasing. In addition, the new algorithm
grants the lock in the same order as the lock was requested whereas
with the old algorithm it was somewhat random which PE waiting for
the lock would get it next.

Adds support for dynamic libraries when using the cce compiler.
