8451d0dd78 In order to maximize the re-usability of kernel code in user space this
patch modifies makesyscalls.sh to prefix all of the non-compatibility
calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel
entry points and all places in the code that use them. It also
fixes an additional name space collision between the kernel function
psignal and the libc function of the same name by renaming the kernel
psignal kern_psignal(). By introducing this change now we will ease future
MFCs that change syscalls.

da6f8233bc Use a mutex to synchronize the driver top and bottom halves instead of
using critcal_enter() and critical_exit() to attempt to replace spl*()
calls.  The critical section was calling selrecord(), which locks an
MTX_DEF mutex, which is not legal in a critical section.

512824f8f7 - Implement selwakeuppri() which allows raising the priority of a
thread being waken up.  The thread waken up can run at a priority as
  high as after tsleep().

- Replace selwakeup()s with selwakeuppri()s and pass appropriate
  priorities.

- Add cv_broadcastpri() which raises the priority of the broadcast
  threads.  Used by selwakeuppri() if collision occurs.

1855be730c Revision 1.126 broke the interface of the bktr driver's
METEORSSIGNAL ioctl.  Applications use this ioctl with the value
METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery,
but revision 1.126 caused the driver to return EINVAL in this case.
Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses
0 to reset signal delivery.

This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the
bktr driver, and restructures the code a bit so that it is otherwise
identical between the bktr and meteor drivers.

30e27d9623 Add a overhaul of the soundchip initialization for the MSP34xx chipsets
found only many tv-cards.

We currently use more ore less evil hacks (slow_msp_audio sysctl) to
configure the various variants of these chips in order to have
stereo autodetection work.  Nevertheless, this doesn't always work
even though it _should_, according to the specs.
This is, for example, the case for some popular Hauppauge models sold
sold in Germany.

However, the Linux driver always worked for me and others.  Looking at
the sourcecode you will find that the linux-driver uses a very much
enhanced approach to program the various msp34xx chipset variants,
which is also found in the specs for these chips.

This is a port of the Linux MSP34xx code, written by Gerd Knorr
<kraxel@bytesex.org>, who agreed to re-release his code under a
BSD license for this port.

A new config option "BKTR_NEW_MSP34XX_DRIVER" is added, which is required
to enable the new driver.  Otherwise the old code is used.

The msp34xx.c file is diff-reduced to the linux-driver to make later
modifications easier, thus it doesn't follow style(9) in most cases.

85f190e4d1 Fixes to make select/poll mpsafe.
Problem:
  selwakeup required calling pfind which would cause lock order
  reversals with the allproc_lock and the per-process filedesc lock.
Solution:
  Instead of recording the pid of the select()'ing process into the
  selinfo structure, actually record a pointer to the thread.  To
  avoid dereferencing a bad address all the selinfo structures that
  are in use by a thread are kept in a list hung off the thread
  (protected by sellock).  When a selwakeup occurs the selinfo is
  removed from that threads list, it is also removed on the way out
  of select or poll where the thread will traverse its list removing
  all the selinfos from its own list.

Problem:
  Previously the PROC_LOCK was used to provide the mutual exclusion
  needed to ensure proper locking, this couldn't work because there
  was a single condvar used for select and poll and condvars can
  only be used with a single mutex.
Solution:
  Introduce a global mutex 'sellock' which is used to provide mutual
  exclusion when recording events to wait on as well as performing
  notification when an event occurs.

Interesting note:
  schedlock is required to manipulate the per-thread TDF_SELECT
  flag, however if given its own field it would not need schedlock,
  also because TDF_SELECT is only manipulated under sellock one
  doesn't actually use schedlock for syncronization, only to protect
  against corruption.

Proc locks are no longer used in select/poll.

dd11af6637 Update to driver 2.15.
Main change is the addition of the bktr_mem module.

This holds onto the bktr driver's contiguously allocated memory
when the bktr driver is unloaded and reloaded.

This has to be done because it is virtually impossible to get
contiguous memory once a system is running.

Also tidied up the use of SMBUS, added a new Hauppauge tuner type (0x2c)
and a new Flyvideo vendor ID.

db90128160 Avoid the modules madness I inadvertently introduced by making the
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.
