Changes paffinity interface to use a cpu mask for available/preferred cpus rather than the current coarse grained paffinity that lets the OS choose which processor. Macros for setting and clearing masks are provided. Solaris and windows changes have not been made. Solaris subdirectory has some suggested changes - however the relevant man pages for the Solaris 10 APIs have some ambiguity regarding order in which one create and sets a processor set. As we did not have access to a solaris 10 machine we could not test to see the correct way to do the work under solaris. This commit was SVN r14887.
