Move log_newpage and log_newpage_buffer to xlog.c.

Browse Source 
log_newpage is used by many indexams, in addition to heap, but for
historical reasons it's always been part of the heapam rmgr. Starting with
9.3, we have another WAL record type for logging an image of a page,
XLOG_FPI. Simplify things by moving log_newpage and log_newpage_buffer to
xlog.c, and switch to using the XLOG_FPI record type.

Bump the WAL version number because the code to replay the old HEAP_NEWPAGE
records is removed.
