[PATCH 1/3] parse-options.h: use consistent name for the callback parameters

["SZEDER Gábor" <szeder.dev@gmail.com>]

In the various OPT_* macros the 'f' parameter is usually used to
specify flags, while the 'cb' parameter is used to specify a callback
function.  OPT_CALLBACK and OPT_NUMBER_CALLBACKS, however, are
inconsistent with the rest, as they use 'f' to specify their callback
function.

Rename their callback macro parameters to 'cb' to avoid the
inconsistency.
