Add comments and a missing CHECK_FOR_INTERRUPTS in ts_headline.
I just spent an annoying amount of time reverse-engineering the 100%-undocumented API between ts_headline and the text search parser's prsheadline function. Add some commentary about that while it's fresh in mind. Also remove some unused macros in wparser_def.c. While at it, I noticed that when commit 78e73e875 added a CHECK_FOR_INTERRUPTS call in TS_execute_recurse, it missed doing so in the parallel function TS_phrase_execute, which surely needs one just as much. Back-patch because of the missing CHECK_FOR_INTERRUPTS. Might as well back-patch the rest of this too.
