revert: use the OPT_CMDMODE for parsing, reducing code

Browse source 
The revert command comes with their own implementation of checking
for exclusiveness of parameters.
Now that the OPT_CMDMODE is in place, we can also rely on that macro
instead of cooking that solution for each command itself.

This commit also replaces OPT_BOOLEAN, which was deprecated by b04ba2bb
(parse-options: deprecate OPT_BOOLEAN, 2011-09-27). Instead OPT_BOOL is
used.
