[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.
