2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

83eb77e880 Make that annoying "device busy" message dependent on DEBUG (using the
DEB macro). There are probably quite a few other messages that warrant
a similar treatment, and many more that should be converted to plain
log messages (e.g. "WARNING: wrintr but write DMA inactive!"). Now
that I think of it, same goes for the CAM code (e.g. the famed "tagged
openings" message)

fe854067c7 Update the pcm driver to the most recent version. This should
add support for Vibra16X, OPTi925, and bring in several assorted
fixes to the code and documentation.
Also present here are apm hooks so that laptops can properly
reconfigure the hardware after suspend (tested on the Libretto50).

a5211c115d Renambed sbintr to sb_intr to avoid a conflict with the (now
unconditionally declared although it can't be configured together
with snd) extern function sbintr.

1747fd3131 Correct even more ioctl breakage :(
Doesn't people check their code before committing anymore, it could
at least compile  ????

4bd4f74b5f there is a minor bug in sb_dsp.c -- the driver
reports ESS cards as able to do 16-bit, but it has no support for it.

0e6400c7f0 - Updated to Luigi's 2-15-98 code. The code in 2.2 is the same except for
select/poll and DEVFS changes, which are limited to an include/define
  in sound.h and the actual select/poll implementation in sound.c

[ This commit is blind, but the code is similar enough that there will
  hopefully be no problems. ]

faac9650a5 This updates Luigi's sound code to the basic code in snd971023...
changes:
    o rip the old select from his distribution to prevent extra pollution
    o the code now uses audio dma, helps reduce clicks
    o improved card support, should work in full duplex on sb16 cards
    o add better voxware ioctl support pointed out by Joao Carlos Mendes
       Luis <jonny@coppe.ufrj.br>
    o remove an unused file that I included for more complete history
    o and MANY other changes

I have personally tested this code with a CS4237 based card and an AWE32
(non-PnP).  Both cards worked fine in 8bit and 16bit mode.
