hangover from previous experimentation. Remove it. This will clean
up gratuitous needs for forward references and other namespace
pollution.

response to return. This will stop processes waiting on DNS requests
from being woken up when a select collision occurs. This was tested
on mx1.FreeBSD.org (outgoing mail for the FreeBSD.org mailing
lists.)

- In ufs_extattr_enable(), return EEXIST instead of EOPNOTSUPP
if the caller tries to configure an attribute name that is
already configured
- Throughout, add IO_NODELOCKED to VOP_{READ,WRITE} calls to
indicate lock status of passed vnode. Apparently not a
problem, but worth fixing.
- For all writes, make use of IO_SYNC consistent. Really,
IO_UNIT and combining of VOP_WRITE's should happen, but I
don't have that tested. At least with this, it's
consistent usage. (pointed out by: bde)
- In ufs_extattr_get(), fixed nested locking of backing
vnode (fine due to recursive lock support, but make it
more consistent with other code)
- In ufs_extattr_get(), clean up return code to set uio_resid
more consistently with other pieces of code (worked fine,
this is just a cleanup)
- Fix ufs_extattr_rm(), which was broken--effectively a nop.
- Minor comment and whitespace fixes.

the existing attribute file rather than aborting with an error.
o Useful if you want to reset the state of attributes on the system without
allocating different disk blocks through deletion and recreation,
for example, if you're doing benchmarks of extended attribute code. :-)

It causes a panic when/if snd_una is incremented elsewhere (this
is a conservative change, because originally no rollback occurred
for any packets at all).

complain before that a suitable gdb port had not been setup because gdbdev
was NULL. This abuses the fact that the gdb port is hard-coded to the
address normally assigned to sio1 and thus hard-codes in sio1 as the gdb
port. Yuck.
released before sleeping and re-acquired before msleep
returns. A compatibility cpp macro has been provided for
tsleep to avoid changing all occurences of it in the kernel.
Remove an assertion that the Giant mutex be held before
calling tsleep or asleep.
This is intended to serve the same purpose as condition
variables, but does not preclude their addition in the
future.
