Add match_limit and match_limit_recursion options
Added to re:run and sets the corresponding fields in 'extra' struct
for the PCRE match engine. The result can be viewed by also
setting 'report_errors' when matching.
Some housekeeping was also done...
The offset option also did not properly check for offset's >= 0.
Change nomatch to BADARG when pre-compiled mp() is faked:
By constructing a 5-tuple with faked content but the right data types,
you could do a re:run which returned nomatch when in fact the mp() was
bad. The cheapest solution is to check the return from pcre_exec
better.
Remove unreachable code in erts_bif_re.c:
Replaced tests for things that logically simply
cannot happen with ASSERT.
