checkpatch: allow reporting C99 style comments

Presently C99 style comments are removed unconditionally before actual patch validity check happens. This is a problem for some third party projects which use checkpatch.pl but do not allow C99 style comments. This patch adds yet another variable, named C99_COMMENT_TOLERANCE. If it is included in the --ignore command line or config file options list, C99 comments in the patch are reported as errors. Tested by processing a patch with a C99 style comment, it passes the check just fine unless '--ignore C99_COMMENT_TOLERANCE' is present in .checkpatch.conf.
