Andres Freund 41d3d64e87 bufmgr: Don't copy pages while writing out 
After the series of preceding commits introducing and using
BufferBeginSetHintBits()/BufferSetHintBits16(), hint bits are not set anymore
while IO is going on. Therefore we do not need to copy pages while they are
being written out anymore.

For the same reason XLogSaveBufferForHint() now does not need to operate on a
copy of the page anymore, but can instead use the normal XLogRegisterBuffer()
mechanism. For that the assertions and comments to XLogRegisterBuffer() had to
be updated to allow share-exclusive locked buffers to be registered.
