[PATCH v3 0/2] Reduce parse-options.o dependencies

This is a reroll of [1]. The main purpose is to make parse-options.o more self-contained so that it at least doesn't pull any extlibs. Immediate usage is for stuff in contrib (svn-fe). Distant application is that some day we could publish this small library separately.

Mostly no changes since [1], just commit message line wrapping, fixup for a Makefile typo and rebase on top of master (new parse_opt_string_list moved to parse-options-cb.c too).
