Subject: builtin-remote: add set-head subcommand

Provide a porcelain command for setting and deleting
$GIT_DIR/remotes/<remote>/HEAD.

While we're at it, document what $GIT_DIR/remotes/<remote>/HEAD is all
about.

+'set-head'::
+
+Sets or deletes the default branch (`$GIT_DIR/remotes/<name>/HEAD`) for
+the named remote. Having a default branch for a remote is not required,
+but allows the name of the remote to be specified in lieu of a specific
+branch. For example, if the default branch for `origin` is set to
+`master`, then `origin` may be specified wherever you would normally

+With `-a`, the remote is queried to determine its `HEAD`, then
+`$GIT_DIR/remotes/<name>/HEAD` is set to the same branch. e.g., if the remote
+`HEAD` is pointed at `next`, "`git remote set-head origin -a`" will set
