* extend parse_proc_head() with support for /parsing/ generic functions (at least in mode Delphi, mode ObjFPC depends on the new isgeneric parameter to be set)
  * adjust parsing of interface mappings with a generic interface (note: in mode ObjFPC this now requires a "specialize" directly before the generic interface's name, which is more in line with other uses of "specialize")
pexpr.pas, factor:
  * don't call postfixoperators() if hadspecialize is set

tests/test/tgeneric79.pp:
  * adjust test to changed syntax
