[PATCH 3/5] classes/package(prserv).bbclass: Added PR service support.

[Lianhao Lu <lianhao.lu@intel.com>]

1. Added package_get_auto_pr to PACKAGEFUNCS to get the auto
incremented value(PRAUTO) from remote PR service.

2. use PKGV/PKGR for pkgdata which will be used by package_write_xxx.

3. Added supporting functions in prserv.bbclass.
