syscall messaging 2: Change the standard return value storage for system

System calls used to set their non-error return value in p_retval[] but
must now set it in the message structure.  This is a necessary precursor to
any sort of asynchronizatino, for obvious reasons.

This work was particularly annoying because all the emualtion code declares
and manually fills in syscall argument structures.

This commit could potentially destabilize some of the emulation code but I
went through the most important Linux emulation code three times and tested it
with linux-mozilla, so I am fairly confident that I got it right.

it will default to SVR4.  It really ought to default to linux (3), not SVR4.

Syscall messaging work 2: Continue with the implementation of sendsys(),

call messages or waiting for messages / port activity.

moment they will always run synchronously. Here's the core interface
code for IA32:

"a"(port), "c"(msg), "d"(msgsize) : "memory");
return(error);

DEV messaging stage 2/4: In this stage all DEV commands are now being
funneled through the message port for action by the port's beginmsg function.
CONSOLE and DISK device shims replace the port with their own and then
forward to the original.  FB (Frame Buffer) shims supposedly do the same
thing but I haven't been able to test it.   I don't expect instability
in mainline code but there might be easy-to-fix, and some drivers still need
to be converted.  See primarily: kern/kern_device.c (new dev_*() functions and
inherits cdevsw code from kern/kern_conf.c), sys/device.h, and kern/subr_disk.c
for the high points.

In this stage all DEV messages are still acted upon synchronously in the
context of the caller.  We cannot create a separate handler thread until
the copyin's (primarily in ioctl functions) are made thread-aware.

Note that the messaging shims are going to look rather messy in these early
days but as more subsystems are converted over we will begin to use
pre-initialized messages and message forwarding to avoid having to constantly
rebuild messages prior to use.

Note that DEV itself is a mess oweing to its 4.x roots and will be cleaned
up in subsequent passes.  e.g. the way sub-devices inherit the main device's
cdevsw was always a bad hack and it still is, and several functions
(mmap, kqfilter, psize, poll) return results rather then error codes, which
will be fixed since now we have a message to store the result in :-)
