Log Message:
-----------
Enhancement to core
1. Add new pvar $hdrcnt(name). Same semantics as $hdr, but returns the number of headers of the given name/type.
2. Add new transform {param.exist,name} which returns 1 if parameter of given name exists, else 0. This is useful for testing params that don't have values (e.g., lr,ob).

Closes patch #3279581
Credits go to Kennard White.
