[ASTERIXDB-2680][FUN] Add support to regexp_matches() and regexp_split()
- user model changes: yes
- storage format changes: no
- interface changes: no
Details:
- Added support to regexp_matches().
- Added support to regexp_split().
- Added test cases for regexp_matches().
- Added test cases for regexp_split().
- Changed behavior of UTF8CharSequence when
subSequence is called with start = end, originally
it returns a null char[] array which causes an NPE,
now it returns an empty char[].
