Subject: Refactor rebuild script

* Use one get_pkgver_sha() function for getting the commit SHA from
  the pkgver variable of a PKGBUILD

* `makepkg --nobuild` updates the pkgver too, so store the old commit
  sha in an associative array using get_pkgver_sha before running
  `makepkg --nobuild`.

* After updating the repos use get_pkgver_sha again to check whether
  the new pkgver is the same as the previous one using get_pkgver_sha()
  instead of the old monstreous get_new_commit() function. If it is do
  nothing, if not add the package to the list of packages to rebuild.

* Use config.bash for configuration variables instead of keeping them
  inside the script.

* Drop the packages associate array since makepkg is now used to refresh
  repositories and make it a normal array just containing the names
  of vcs packages instead.

* Since makepkg takes care of refreshing repos we don't need to keep
  track of the branches ourself, so drop the branches associative array
  from the package list file.
