  1. Avoid re-parsing by pre-computing a method-body table 

    RDoc::Parser::C#find_body parsed file_content every time to find the
method body.  Now it creates a method-body table first, which avoid
mutliple parsing.

  4. Remove an extra branch from the bottleneck 

    RDoc::RubyLex#getc is the bottleneck in RDoc.  It determined which
ungetc buffer to use by branching upon `@here_header`.  We can remove
the branch by replacing `@here_header` flag with `@current_readed`,
which represents the current buffer directly,
