remote: add --fetch and --both options to set-urlpw/remote-set-url-fetch

git remote set-url knew about the '--push' option to update just the
pushurl, but it does not have a similar option for "update fetch URL and
leave whatever was in place for the push URL".

This patch adds support for a '--fetch' option which implements that use
case in a backwards compatible way: if no --both, --push or --fetch
options are given, then the push URL is modified too if it was not set
before. This is the case since the push URL is implicitly based on the
fetch URL.

A '--both' option is added to make the command independent of previous
pushurl settings. For the --add and --delete set operations, it will
always set the push and/ or the fetch URLs. For the primary mode of
operation (without --add or --delete), it will drop pushurl as the
implicit push URL is the (fetch) URL.

The documentation has also been updated and a missing '--push' option
is added to the 'git remote -h' command.

Tests are also added to verify the documented behavior.
