RDoc::Parser::C: Integrate do_classes and do_modules by one regexp match The full scan of the C source code (`@content.scan`) is very slow. The old code invokes the scan six times in `do_classes` and `do_modules`. This change integrates the six scans into one by merging the regexps. The integrated regexp is a bit hard to maintain, but the speed up is significant: approx. 30 sec -> 20 sec in Ruby's `make rdoc`. In addition, this change omits `do_boot_defclass` unless the file name is `class.c`. `boot_defclass` is too specific to Ruby's source code, so RDoc should handle it as a special case.
