[svn-r12686] Added compression to Packet Tables.  Now both C and C++ packet tables
have an extra parameter that sets the deflate filter.

Added tests, made examples use the new APIs.

Cleaned up include files a little and removed some casts that I hope are
superfluous.  If anybody encounters strange errors in the packet table
tests where the chunk size is set to some extremely large value, please
let me know, but I was unable to reproduce this error on any system.

Tested on mir, heping, sol, juniper, VS 6.0.  Looked for the chunk size
error on several other systems a month or two ago.
