kept unused in the ring. This check should probably be moved up to
bce_start_locked at some point, as it'll make the loop up there slightly
more efficient, and will eliminate a costly set of busdma operations when
the ring is full. But this works for now.
This makes all of my UDP torture tests work. I'll cautiously say that
it might even work for other users now. Feedback is appreciated.

syscalls using __syscall but only actually returning 32bits, such as mmap(),
specially : they set the return value in td->td_retval[0], but the userland
functions will expect this in r1, and not in r0 as it is normally done, as it
is the LSB. So add a special case for all these syscalls (all except lseek,
which truly returns 64bits).
Many thanks to Peter Grehan for his patience while explaining me the issue.

If the length is zero, catch this early, instead of making dflen go negative
and letting bad things happen... We also check to see if RV (checksum) is
0, and handle that has a checksum failure...
Properly handle checksum failures by not processing read-write VPD data,
and removing all the found read-only data...

processes. It was originally added back when support for Linux threads
(and thus shared sigacts objects) was added, but no one knows why. My
guess is that at some point during the Linux threads patches, the sigacts
object was torn down during exit1(), so this check was added to prevent
a panic for that race. However, the stuff that was actually committed to
the tree doesn't teardown sigacts until wait() making the above race moot.
Re-allowing signals here lets one interrupt a NFS request during process
teardown (such as closing descriptors) on an interruptible mount.

Massive update. The highlights:
o dramatically cut memory usage by writing better, less intertwingled
code.
o implement booting off mmc/sd cards (sd only tested one at the moment)
o start to split out board specific stuff for boot2.

- Drop redundant includes of sys/cdefs.h and sys/_types.h as sys/ipc.h
