2a275e6d3c Fix pg_buffercache to release buffer partition locks in reverse order,
and add a note about why.  This is not tremendously important right now,
probably, but it will get more urgent if NUM_BUFFER_PARTITIONS is increased
as much as proposed.

10b9ca3d05 Split the buffer mapping table into multiple separately lockable
partitions, as per discussion.  Passes functionality checks, but
I don't have any performance data yet.

07eeb9d109 Do all accesses to shared buffer headers through volatile-qualified
pointers, to ensure that compilers won't rearrange accesses to occur
while we're not holding the buffer header spinlock.  It's probably
not necessary to mark volatile in every single place in bufmgr.c,
but better safe than sorry.  Per trouble report from Kevin Grittner.
