As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and
PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a
value of an unknown option could be mistakenly classified as a
non-option, stopping the parser early. E.g.:
git cmd --known --unknown value arg0 arg1
The parser should have stopped at "arg0", but it already stops at
"value".
This patch makes parse_options() die if the two flags are used in
combination.

Most of them are still stubs, but the procedure to build the HTML
documentation, maintaining the index and installing the end product are
there.
I placed names of people who are likely to know the most about the topic
in the stub files, so that volunteers will know whom to ask questions as
needed.
