perf tools: Add parser generator for events parsing
Changing event parsing to use flex/bison parse generator.
The event syntax stays as it was.

Added flex/bison files for event grammar parsing. The generated
parser is part of the patch. Added makefile rule 'event-parser'
to generate the parser code out of the bison/flex sources.
