2af417add4 Make grep run much (~10x) faster in multibyte locales by caching the wide 
character representation of input data across calls to dfaexec(), and by
caching the lengths of character across calls to check_multibyte_string().

dd5c240f7a Merge FreeBSD changes into 2.3: 
* rev 1.2 - use -lgnuregex

FreeBSD changes OBE'ed by 2.3:
* revs 1.4-5 - icase searches & ctype macro changes, fuctionality moved
               elsewhere.
* rev 1.3 - Remove trailing whitespace.  The GNU Grep maintainers did this
            for us.

c18f2d82a5 Back out the botched attempt to update to gnu grep 2.3 (lots of history 
was lost).  Restore original version to try and avoid breaking the build
while David O'brien does a proper set of imports and merges.
