kwset: speed up by using memchr2
Idea suggested by Eric Blake in: http://bugs.gnu.org/17229#43
* bootstrap.conf (gnulib_modules): Add memchr2.
* src/kwset.c: Include stdint.h, for uintptr_t. Include memchr2.h.
(struct kwset): New members gc1, gc2, gc1help.
(tr): Move earlier, so it can be used earlier.
(kwsprep): Initialize struct kwset's new members.
(memchr_kwset): Rename from memchr_trans. Combine C and TRANS args into
new arg KWSET. All uses changed. Use memchr2 when appropriate.
(bmexec): Use new members instead of recomputing their values.
Increase advance_heuristic; it's just a guess, but memchr2 probably
makes it reasonable to increase it.
