skype 2.1.0.81; alternate versions of the Linuxolator v4l2 patches

[Juergen Lock]

Hi!

 I somehow thought my linux-v4l2-8-test.patch would also apply
on 8.2 but of course it doesn't so I now also made q&d versions
for that version:

	http://people.freebsd.org/~nox/dvb/linux-v4l2-8.2-test.patch

and the same with Linux 2.6.17 videodev2.h:

	http://people.freebsd.org/~nox/dvb/linux-v4l2-2.6.17-8.2-test.patch

 And I also don't want to keep back ae@'s version which builds
as a seperate kld the way I did it for the Linuxolator dvb handler
that is now in ports as multimedia/linux_dvbwrapper-kmod:

	http://people.freebsd.org/~ae/linux_v4l2_kld.tgz

 Maybe we should turn this into a port too for easy user installation
until the patches get committed and for people on (current) releases?

 (See http://people.freebsd.org/~nox/dvb/ for the others versions.)

 I now tested skype 2.1.0.81 on 8.2 with the above patch and
avg@'s sys/dev/sound/pcm/dsp.c one-line patch [1], and found
sound doesn't work when running skype from nfs without locking
(wtf!), after extracting the skype tarball [2] locally it started
working.

 I installed these ports:

	multimedia/webcamd

	net/skype
	(for the deps [3])

	audio/linux-f10-alsa-plugins-oss
	(if you use the default /compat/linux/etc/asound.conf
	don't forget to switch skype's audio input/outputs from
	`default' to `oss', and if your mic isn't on the default
	soundcard you also need to add that to the Linux config [4]
^	and select it in skype)

	audio/alsa-plugins
	(I already had it installed among other things, might not
	actually be needed)

	dns/linux-f10-libasyncns

	multimedia/linux-f10-libv4l
	(for the Linux v4l2convert.so that my cam needs)

 And again I ran skype out of the extracted tarball:

	LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so ./skype_static-2.1.0.81/skype --resources=$PWD/skype_static-2.1.0.81

 (I also tested the latest beta [5] using a pcbsd 9.0 liveusb
snapshot but it still didn't want to work for me, something about
kwm@'s setup must really be `special', he's the only one I know of
that has it working...)

 Enjoy, :)
