bitbake: Automatically start local PR service. 

[YOCTO #1126]
A local PR service will be started and stopped automatically along
with the bitbake invocation/ternimation.

This local PR service will be started only and if only when the
PRSERV_HOST is set to 'localhost' and PRSERV_PORT is set to '0'.

When started, the sqlite3 database is stored at
"${PERSISTEN_DIR}/prserv.sqlite3" or "${CACHE}/prserv.sqlite3".

(Bitbake rev: 9d8f45407c67ed0d3c4f820cf646de3c385067c7)
