builtin rebase: support --onto
The `--onto` option is important, as it allows to rebase a range of
commits onto a different base commit (which gave the command its odd
name: "rebase").
This commit introduces options parsing so that different options can
be added in future commits.
Note: As this commit introduces to the parse_options() call (which
"eats" argv[0]), the argc is now expected to be lower by one after this
patch, compared to before this patch: argv[0] no longer refers to the
command name, but to the first (non-option) command-line parameter.
