It turns out I overlooked some function prototypes that were actually
TTY related, but were stored in <sys/conf.h> to implement the D_TTY
flag. Remove these prototypes now that they don't exist anymore.

64-bit DMA addresses for interrupt queues and data is not uniform across
slices.

the gvinum header in fields of fixed size and in a big endian byte order
rather than the size and byte order of the actual platform.
Note that the change is backwards compatible with the old gvinum configuration
format, but will save the configuration in the new format when the 'saveconfig'
command is executed.

- Update or remove comments that were left over from the original
soreceive_generic() implementation. Quite a few were misleading in the
context of the new code.
- Since soreceive_dgram() has a simpler structure, replace several gotos
with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
the loop invariant (since m is always NULL, don't check for and handle
non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
sbwait() returns, which may help reduce lock contention (etc).
- Assume PR_ATOMIC since we assert it at the top of the function.

Also, fix a minor style(9) nit.

In my previous commit I disabled pkill(1)'s automatic prepending of the
"tty" string when `pkill -t' was being used. Re-enable it and stat()
both possible device names when called.

We don't lose any statistics with this change, because in a error
