Teach regular expression operators to honor collations.
This involves getting the character classification and case-folding functions in the regex library to use the collations infrastructure. Most of this work had been done already in connection with the upper/lower and LIKE logic, so it was a simple matter of transposition. While at it, split out these functions into a separate source file regc_pg_locale.c, so that they can be correctly labeled with the Postgres project's license rather than the Scriptics license. These functions are 100% Postgres-written code whereas what remains in regc_locale.c is still mostly not ours, so lumping them both under the same copyright notice was getting more and more misleading.
