dadac8f503 Add select to list on compat syscalls. Makes some code work for 
me with a nb5 userland without having to compile with -g ;)

8b9126ba6d If a thread wake up spuriously, re-set l_mutex to make sure it's 
still at the original value and not the schedstate one.  This makes
select not miss wakeups in cases where there was a lot of selecting
going on (which is not all that common in a rump kernel).

f3c8997bfe Reset l_mutex when waking up a thread. select uses it to determine 
if a thread is still selecting, and would get a KASSERT panic if
the thread had been woken up but not run yet when selnotify() was
called.

01497b95ec Convert swwdog(4) from a simple defpseudo device to a defpseudodev so 
that we can attach a power management handler.  The handler prevents
a suspend if the watchdog is active, to be consistent with other
watchdog drivers.

As discussed on tech-kern.

7949f6c1c8 Don't provide stat compat syscalls here, they come from 
rump_syscalls_compat.h now.  (besides, I always hated how they were
in the rump_pub_sys namespace instead of the rump_sys namespace)

bcc65ff09f Split-off IPv4 re-assembly mechanism into a separate module. Abstract 
into ip_reass_init(), ip_reass_lookup(), etc (note: abstraction is not
yet complete).  No functional changes to the actual mechanism.

0882d1cc0e Emulate malloc(9) a little better by panicking if a should-not-fail 
allocation fails.  We could invoke the pagedaemon here, but since
malloc(9) is panicky when it runs out of kmem_map, let's do the
"same".

c9602161d3 Make putter its own component: rumpdev_putter. It was coupled in 
with rumpfs_puffs for prehistoric reasons which are no longer valid

9cb9168c28 Calculate memory mapping size based on underlying file size, not 
our window to it.  This fixes cases like opening a window at offsets
[8,32] to a file, which would cause host file offset [0,32-8] to
be mapped, i.e. [0,16] inside the window.  Obviously, access to
the entire in-window [0,24] range should have been mapped (and
after this fix it is).

cd3e4f8ebc Reinstate the blanket pmap.h for archs which do not conform to the 
kernel ABI (i.e. not i386 or amd64).  Due to the "half function,
half macro, all noodles" nature of pmap.h, it's too entangling and
too brittle to keep up with an ifdeffy MI implementation.
