Default repo manifest settings in git config

A default manifest URL can be specified using:
  git config --global repo-manifest.<id>.url <url>

A default manifest server can be specified using:
  git config --global repo-manifest.<id>.server <url>

A default git mirror reference can be specified using:
  git config --global repo-manifest.<id>.reference <path>

This will allow the user to use 'repo init -u <id>' as
a shorter alternative to specifying the full URL.

Also, manifest server will not have to be specified in the
manifest XML and the reference will not have to be specified
on the command line. If they are, they will override these
default values however.

 The optional -b argument can be used to select the manifest branch
 to checkout and use.  If no branch is specified, master is assumed.
