builtin/push.c: add push.pushOption config

Push options need to be given explicitly, via the command line as "git
push --push-option <option>".  Add the config option push.pushOption,
which is a multi-valued option, containing push options that are sent
by default.

When push options are set in the lower-priority configulation file
(e.g. /etc/gitconfig, or $HOME/.gitconfig), they can be unset later in
the more specific repository config by the empty string.

Add tests and update documentation as well.
