[PATCH/RFC v2 1/2] parse-options: export opterr, optbug

[Dmitry Ivankov <divanorama@gmail.com>]

opterror and optbug functions are used by some of parsing routines
in parse-options.c to report errors and bugs respectively.

Export these functions to allow more custom parsing routines to use
them in a uniform way.
