JDK-7127700 - G1: Replace G1PLAB with PLAB
Description
Rename ParGCAllocBuffer to the nowadays much more common abbreviation PLAB since it is lengthy.

Also rename the files.
Comments
This change has originally been spawned from the review of JDK-8073052. It would be nicer if the renaming of ParGCAllocBuffer to PLAB (also for G1) would be done before that change, so that there is never a point where one is renamed but not the other. The _retired functionality change should be done as part of JDK-7127700 (if applicable) then.

JDK-7127700 is some existing code cleanup request to look at the usefulness of the _retire functionality it G1PLAB.
