eliminate octave_comment_buffer singleton
* lex.h (octave_base_lexer::comment_buffer): New class adapted from
octave_comment_buffer class. No longer a singleton class.
(octave_base_lexer::comment_buffer::reset): New function.
(octave_base_lexer::reset): Call comment_buf.reset.
(octave_base_lexer::comment_buf): New data member.
(octave_base_lexer::get_comment): New function.
* comment-list.h, comment-list.cc (octave_comment_buffer): Delete.
Change all uses of octave_comment_buffer to use local comment_buf
object instead.
* parse.h (octave_base_parser::make_statement): New member function.
* oct-parse.in.yy (make_statement): Delete.
Change all uses of make_statement to use the member function instead.
(safe_fclose): Don't extract and delete comment list here.
