Subject: [Patch] Rewrite _StateSeq in regex
Authentication-results: sourceware.org; auth=none

This patch fix the optional operator '?' and interval repeating like
"a{3,5}" through rewrite _StateSeq.

After this patch, the assertion supporting shall be the last
significant feature to be implemented.

It's booted and tested under x86_64. It'll be fully tested before committing.

Thanks!
