This is a saner alternative than hardcoding the default branch to be "master". The add_repo() function will now check for a symbolic ref in repo_path/HEAD. If there is a suitable one, overwrite repo->defbranch with it. Note that you'll need to strip the newline from the file (-> len-17).
If HEAD is a symbolic link pointing directly to a branch below refs/heads/, do a readlink() instead to find the ref name.
