NFS swap fix. Most files here are modified purely to add a tsleep() wmesg
...
string. The actual functional changes are:
1. in vm_page_alloc(), restore some long lost code by Paul Kranenburg
that reserves the last few pages for kernel objects, adding an
additional escape for the pageout daemon.
2. In vm_wait() (replaces VM_WAIT), recognize the amusing fatal
deadlock where the pagedemon sleeps on a channel that only it ever
wakes up, and add a timeout and printf. Mod 1 should generally
prevent this from happening in any case.
3. Fix a livelock in vm_pageout_page() caused by a pre-wakeup of
page consumers prior to the pageout, which can easily fail over
memory issues in NFS and IP code. Also, ++ cnt.v_pageouts only
if the pageout succeeded.

Adapt a diagnostic to big-endian machines.
...
(Not that it actually works on little-endians, but we can easily make it not
work on big-endians all the same).

Define a macro to test if an object has pages in transit. Clarify

some arithmetic, and nuke an unneeded prototype.

This is all from mycroft:
...
Create macros (with names borrowed from Mach 3) to manipulate
object->paging_in_progress, and use them. When decreasing the
paging count, always make sure to wake up anyone waiting.
Fixes `vospgc', `vosca1', and `vosca2' hangs.

add thread_sleep_msg() that takes a wait message, and change thread_sleep()

into a macro for backwards compat. alter vm_object_sleep() to take advantage
of this.
