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.
Before this change:
TOTAL (pct) SAMPLES (pct) FRAME
858 (13.6%) 858 (13.6%) (garbage collection)

205 (3.2%) 205 (3.2%) RDoc::Parser::C#do_singleton_class
The six methods take approx. 22.2%.
`do_define_class` (4.2%) + `do_define_class_under` (3.8%) +
`do_define_module` (3,9$) + `do_define_module_under` (3.7%) +
`do_struct_define_without_accessor` (3.4%) + `do_singleton_class` (3.2%)
After this change, the methods are integrated to `do_classes_and_modules`
which takes only 5.8%.
