builtin/stash.c: let parse-options parse subcommands
'git stash' parses its subcommands with a long list of if-else if
statements. parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
and listing subcommands for Bash completion.
Note that the push_stash() function implementing the 'push' subcommand
accepts an extra flag parameter to indicate whether push was assumed,
so add a wrapper function with the standard subcommand function
signature.
Note also that this change "hides" the '-h' option in 'git stash push
-h' from the parse_option() call in cmd_stash(), as it comes after the
subcommand. Consequently, from now on it will emit the usage of the
'push' subcommand instead of the usage of 'git stash'. We had a
failing test for this case, which can now be flipped to expect
success.
