Sync our regex code with upstream changes since last time we did this, which was Tcl 8.5.11 (see commit 08fd6ff37f71485e2fc04bc6ce07d2a483c36702). The only functional change here is to disbelieve that an octal escape is three digits long if it would exceed \377. That's a bug fix, but it's a minor one and could change the interpretation of working regexes, so don't back-patch. In addition to that, s/INFINITY/DUPINF/ to eliminate the risk of collisions with <math.h>'s macro, and s/LOCAL/NOPROP/ because that also seems like an unnecessarily collision-prone macro name. There were some other cosmetic changes in their copy that I did not adopt, notably a rather half-hearted attempt at renaming some of the C functions in a more verbose style. (I'm not necessarily against the concept, but renaming just a few functions in the package is not an improvement.)
