    Convert util/mkrel to use git instead of svn
    
    (cherry picked from commit 933798d193ac406b43724f02837e401db09827e3)
    
    Update CHANGES file generation for Git
    
    Use the correct git log invocation for generating the CHANGES file.
    (cherry picked from commit 6d204bc466e2038bacf3e2e3a4b4f5bdc56e6b5e)
    
    Make mkrel work on non-master branches
    
    Appending "--" to the git checkout arguments appears to prevent it
    from automatically creating a local branch from the remote.  Also
    correct the default git URL and clean up a spurious find warning.
    (cherry picked from commit 4fc9c72e5d30c94399baf7069a0d0db25e940a68)
