Subject: [PATCH] Optional LOCALCOUNT for recipe

* Instead of autoincrement from persistent cache when srcrev is changed.
* Should be used by distributions with multiple builders, where consistent
  PV is needed.
* Can be used instead of PR bump in PVs like this "0.0+${PR}+gitr${SRCPV}"
* BB_LOCALCOUNT_OVERRIDE to enable setting LOCALCOUNT for recipe
* This way LOCALCOUNTs can be specified directly in recipes instead of
  separated distro config (as not all want to use them). And will be
  used only when BB_LOCALCOUNT_OVERRIDE set in distro config.
