b377be43a5 Add TIOCPKT and TIOCSPTLCK to the Linuxolator.
We're very lucky, because the flags used by our TIOCPKT implementation
are the same as flags used by Linux. We can safely enable TIOCPKT,
assuming EXTPROC is not used.

TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in
our implementation, make this ioctl a no-op.

d60f0a3d6a Implement LINUX_SIOCGIFCOUNT and LINUX_SIOCGIFINDEX/LINUX_SIOGIFINDEX.
LINUX_SIOCGIFCOUNT just returns 0 since it is not implemented in the
Linux 2.6.16.

LINUX_SIOCGIFINDEX/LINUX_SIOGIFINDEX are mapped to the FreeBSD native
SIOCGIFINDEX.

1eba4c7948 Add the CAM 'SG' peripheral device. This device implements a subset of the
Linux SCSI SG passthrough device API.  The intention is to allow for both
running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate
porting of apps from Linux to FreeBSD.  As such, both native and linuxolator
entry points and definitions are provided.

Caveats:
 - This does not support the procfs and sysfs nodes that the Linux SG
   driver provides.  Some Linux apps may rely on these for operation,
   others may only use them for informational purposes.
 - More ioctls need to be implemented.
 - Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a
   scheme of "sg[0-9]".  Devfs aliasis (symlinks) are automatically created
   to link the two together.  However, tools like camcontrol only see the
   native names.
 - Some operations were originally designed to return byte counts or other
   data directly as the syscall return value.  The linuxolator doesn't appear
   to support this well, so this driver just punts for these cases.

Now that the driver is in place, others are welcome to add missing
functionality.  Thanks to Roman Divacky for pushing this work along.

e83d253beb Linux compat bits needed to make linux programs use the new ptys :
linux_ioctl.[ch] : Implement LINUX_TIOCGPTN, which returns the pty number
linux_stats.c :
	- Return the magic number for devfs.
	- In various stats()-related functions, check that we're stating a
file in /dev/pts, and if so, change the st_rdev field to match what linux
expects to be there for a slave pty device. The glibc checks for this, and
their openpty() fails if it is no correct.

3ad9c842d2 - Add support for IPC_64 extensions into shmctl(2), semctl(2) and msgctl(2);
- add wrappers for mmap2(2) and ftruncate64(2) system calls;
- don't spam console with printf's when VFAT_READDIR_BOTH ioctl(2) is invoked;
- add support for SOUND_MIXER_READ_STEREODEVS ioctl(2);
- make msgctl(IPC_STAT) and IPC_SET actually working by converting from
  BSD msqid_ds to Linux and vice versa;
- properly return EINVAL if semget(2) is called with nsems being negative.

b0cb4883b1 Deal with a few issues that cropped up following the recent changes
to the code for translating socket and private ioctls:

- Only perform socket ioctl translation if the file descriptor is a
  socket.
- Treat socket ioctls on non-sockets specially, and for now assume
  that these are directed at a tap/vmnet device, so translate the
  ioctl numbers as appropriate (the way if_tap abuses some socket
  ioctls to pass non-ifreq data is utterly bogus, but this is how
  VMware on FreeBSD has always "worked"; I will deal with this
  later).
- Add (untested) support for translating SIOCSIFADDR.
- In all cases where we fail to translate an ioctl, return ENOIOCTL
  so that other handlers have a chance to do the translation.

This should fix the "/dev/vmnet1: Invalid argument" errors that
users of VMware were experiencing, though I have only verified this
on RELENG_4.

3c7b85d4f0 Fix Alpha related brokenness. We used to have a MD linux_ioctl.h
that appeared to be very different from the MI version. These
differences were mostly bogus and caused by copying octal
definitions and write them as hexadecimal values without doing
any base conversion (ie 010 was copied to 0x10). After filtering
out these differences, any remaining (real) incompatibilities
have been merged into the MI header file to make them more visible.

While here, fix the termios <-> termio conversion WRT to the c_cc
field for Alpha. The termios values do not match the termio values
and thus prevents us from copying.

By eliminating the Alpha MD copy of linux_ioctl.h we also fixed
the recent build breakage caused by putting new bits in the MI
header and not in the MD header.

b51cc76c45 Add support for the "device private" ioctls soon to be used by the an driver.
Also slightly change the name translation policy - only rename interfaces
that have the IFF_BROADCAST flag set.  This is not perfect, but is closer to
how Linux names network interfaces.

43bef51567 Implement pluggable ioctl handlers.
Other modules can register and unregister ioctl handlers to extend the
ioctls known by the Linuxulator. A recent application is the vmware
port. The Linuxulator itself uses the new interface to register its
handlers as well. Handlers for the following types of ioctls have been
defined:
	cdrom
	console (=keyboard and VT handling)
	socket
	sound
	termio

All ioctl related defines and declarations have been moved to a new
file (linux_ioctl.h), except for the pluggable ioctl handler interface
definition.

While there, cleanup linux.h some more.

linux.h and linux_ioctl.[ch] have been made to conform to style(9) as
much as possible.
