IVTV changes:

0.3.8 release
	- switched to subversion, all old archives are imported in
	  chronological order.
	- the comment field of the version string now holds the svn revision.
	- for tagged releases a driver/ivtv-svnrelease.h header must be added
	  to the tags/X.Y.Z driver containing a fixed release string.
	- moved ChangeLog to ChangeLog.old and started a new one for the
	  subversion development.
	- upped the version to 0.3.8 to mark these changes.
	- updated the README file with information where to find the
	  subversion repository.
	- Fix radio support for Microtune 4049 FM5 tuner
	- Fix incorrect pack_stuffing_length in the embedded VBI mpeg
	  header, causing tcdecode to fail.
	- [Bryan Mayland] Added README.tda9887
	- Removed linux/stringify.h include from ivtvctl.c. Not everyone had
	  this installed.
	- IVTV_IRQ_DEC_VSYNC should only be set for cards with video output.
	- Fixed uninitialized vps variable.
	- [Boleslaw Ciesielski] Do not buffer vbi output.
	- Replace the ivtv-specific sliced VBI API with the new video4linux
	  sliced VBI API. This will break any program that uses the following
	  ioctls: IVTV_IOC_S_VBI_MODE, IVTV_IOC_G_VBI_MODE, IVTV_IOC_S_VBI_FMT,
	  IVTV_IOC_G_VBI_FMT, IVTV_IOC_TRY_VBI_FMT and IVTV_IOC_G_VBI_CAP.
	- Do not passthrough VBI data that is not in the expected line/field.
	- Autodetect the presence of a tda9887.
	- Ticket #4: poll() bug fix: check whether the given file is capturing,
	  not if *any* file is capturing. This blocked simultaneous MPEG and raw
	  VBI captures.
	- Changed the default of ivtv_dynbuf to static memory allocation.
	- Closes #5: correctly swap VBI reinsertion data when fed a non-4-byte
	  aligned mpeg file.
	- Fix VIDIOC_QUERYMENU and add VIDIOC_G_FBUF.
	- Closes #19: properly handle /dev/vbi0 and /dev/vbi4 in combination
	  with the internal VBI encoder/decoder streams.
	- YUV playback defaults to interlaced instead of auto_switching to
	  progressive for content less than 481 lines. ivtvctl has 2 new
	  options --get-yuv-mode & --set-yuv-mode that can get and set the
	  current mode. 
	- The default yuv payback mode & threshold can be set by the
	  module option ivtv_yuv_mode & ivtv_yuv_threshold
