avoid unnecessary aging of buffers. This used to make sense, when buffer

caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow. Suggested by Bob Baron.

bdwrite() should upgrade writes to tape devices by sending them to
...
bawrite(). it's logically more correct (doesn't return an error code,
because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended. Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.

fix long-standing XXX in getblk(): NFS does funky things (somewhat

explained in comments), which can cause a race condition. amazingly,

a DEC OSF/1 NFS server running on an Alpha.
