Merge change Iac63ebc8 into eclair-mr2

* changes:
  Make WRITE_GSERVICES into system-or-signature (instead of just signature), as a temporary measure so unbundled Google components (GSF, etc.) can hold it.  (In the longer term, WRITE_GSERVICES won't be a system permission at all, but it or something like it will be defined directly by GSF.)
