Subject: [PATCH] parse: dump option type when using --debug=parse

Currently we do things like:

parse    8731  __handle_option=dummy, type=10, ptr=1

for the debug parsing, and then you have to look up what that
option type is. Add names to them so we get the below instead:

parse    9170  __handle_option=dummy, type=OPT_STR_SET, ptr=1
