* introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals
the owner of descriptor, according to appropriate sematics
of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use
these routines instead of custom code where appropriate
* make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN
properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP
in sys_ioctl() & sys_fcntl()
* also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and
pass the ioctls down to soo_ioctl() as any other ioctl
change discussed on tech-kern@
Some initial support for IOHIDSystem. This gives us some pointer moves in X11
(not really related the the actual mouse movement, but this will come).
The darwin_iohidsystem_thread reads events from wscons, translates them
into IOHIDSystem events and wakes up the userland client with a notification.
To do this, I had to improve the void implementation of
io_connect_set_notification_port() to actually register something (I assumed
a single notification port, which makes some sense since only one process
seems to be able to open the driver)
Missing bits:
- we do not take event masks given by the process into account.
- the notification message has not been checked against Darwin
- events are badly translated

and make the stack and heap non-executable by default. the changes
fall into two basic catagories:
- pmap and trap-handler changes. these are all MD:
= alpha: we already track per-page execute permission with the (software)
PG_EXEC bit, so just have the trap handler pay attention to it.
= i386: use a new GDT segment for %cs for processes that have no
executable mappings above a certain threshold (currently the
bottom of the stack). track per-page execute permission with
the last unused PTE bit.
= powerpc/ibm4xx: just use the hardware exec bit.
= powerpc/oea: we already track per-page exec bits, but the hardware only
implements non-exec mappings at the segment level. so track the
number of executable mappings in each segment and turn on the no-exec
segment bit iff the count is 0. adjust the trap handler to deal.
= sparc (sun4m): fix our use of the hardware protection bits.
fix the trap handler to recognize text faults.
= sparc64: split the existing unified TSB into data and instruction TSBs,
and only load TTEs into the appropriate TSB(s) for the permissions.
fix the trap handler to check for execute permission.
= not yet implemented: amd64, hppa, sh5
- changes in all the emulations that put a signal trampoline on the stack.
instead, we now put the trampoline into a uvm_aobj and map that into
the process separately.
originally from openbsd, adapted for netbsd by me.
truncate64() wrapper to translate args structure
NetBSD truncate() and ftrucate() have hidden 'pad' argument, so we have
to do the argument translation
Problem found and patch supplied in PR kern/22360 by Ales Krenek
This is the last of syscalls with hidden 'pad' arg we didn't have
wrapper for; all the others (lseek, mmap, pwrite, pread) already had
wrapper before.
address. We do that through the irix_load_addr function, which is
not IRIX specific at all. If another emulation needs it, it can
easily move to compat_util.c
With this change, IRIX dynamic binaries are able to link and run again
(top down UVM broke them a few weeks ago)
* translate MSG_* flags
* rewrite CMSG level/type to appropriate NetBSD value on input, and to Linux
value on output
* handle different CMSG_DATA alignment for some archs
This fixes SCM_RIGHTS passing. Other SCM_* types are not supported -
the set is different on NetBSD and Linux. SCM_TIMESTAMP doesn't seem
to be actually implemented in Linux 2.5.15, so it's not supported
for Linux binaries either (for now).

fix value for LINUX_SO_DETACH_FILTER on couple places (unused anyway)
g/c LINUX_SCM_TIMESTAMP definition for some archs, it will be defined
in generic linux_socket.h
