Make the ssl expression parser thread-safe. It now requires bison instead of

yacc.

Also change the make file magic so that the real source file name is
embedded in the debug info.

The generated files have been created with flex 2.5.35/bison 2.4.1. The two
'no previous prototype' warnings are supposed to be fixed with the next flex
version.
