Move the buffered read/write code out of spec_{read|write} and into
two new functions spec_buf{read|write}.

Add sysctl vfs.bdev_buffered which defaults to 1 == true.  This
sysctl can be used to experimentally turn buffered behaviour for
bdevs off.  I should not be changed while any blockdevices are
open.  Remove the misplaced sysctl vfs.enable_userblk_io.

No other changes in behaviour.
