vo_zr2: drop Zoran support 

There were multiple files specific to Zoran support, and they also
depended on internal FFmpeg headers (so it would probably have been
hard to get them to compile now even if you tried). It's obsolete now,
so just drop the whole mess.

drivers.

.TP
.B \-zrbw (\-vo zr only)
Display in black and white.
For optimal performance, this can be combined with '\-lavdopts gray'.
.
.TP
.B \-zrcrop <[width]x[height]+[x offset]+[y offset]> (\-vo zr only)
Select a part of the input image to display, multiple occurrences
of this option switch on cinerama mode.
In cinerama mode the movie is distributed over more than one TV
(or beamer) to create a larger image.
Options appearing after the n-th \-zrcrop apply to the n-th MJPEG card, each
card should at least have a \-zrdev in addition to the \-zrcrop.
For examples, see the output of \-zrhelp and the Zr section of the
documentation.
.
.TP
.B \-zrdev <device> (\-vo zr only)
Specify the device special file that belongs to your MJPEG card, by default
the zr video output driver takes the first v4l device it can find.
.
.TP
.B \-zrfd (\-vo zr only)
Force decimation: Decimation, as specified by \-zrhdec and \-zrvdec, only
happens if the hardware scaler can stretch the image to its original size.
Use this option to force decimation.
.
.TP
.B \-zrhdec <1|2|4> (\-vo zr only)
Horizontal decimation: Ask the driver to send only every 2nd or 4th
line/\:pixel of the input image to the MJPEG card and use the scaler
of the MJPEG card to stretch the image to its original size.
.
.TP
.B \-zrhelp (\-vo zr only)
Display a list of all \-zr* options, their default values and a
cinerama mode example.
.
.TP
.B \-zrnorm <norm> (\-vo zr only)
Specify the TV norm as PAL or NTSC (default: no change).
.
.TP
.B \-zrquality <1\-20> (\-vo zr only)
A number from 1 (best) to 20 (worst) representing the JPEG encoding quality.
.
.TP
.B \-zrvdec <1|2|4> (\-vo zr only)
Vertical decimation: Ask the driver to send only every 2nd or 4th
line/\:pixel of the input image to the MJPEG card and use the scaler
of the MJPEG card to stretch the image to its original size.
.
.TP
.B \-zrxdoff <x display offset> (\-vo zr only)
If the movie is smaller than the TV screen, this option specifies the x
offset from the upper-left corner of the TV screen (default: centered).
.
.TP
.B \-zrydoff <y display offset> (\-vo zr only)
If the movie is smaller than the TV screen, this option specifies the y
offset from the upper-left corner of the TV screen (default: centered).

.IPs maxheight=<h>|maxwidth=<w>
These options set the maximum width and height the zr card
can handle (the MPlayer filter layer currently cannot query those).
.IPs {dc10+,dc10,buz,lml33}-{PAL|NTSC}
Use these options to set maxwidth and maxheight automatically to the
values known for card/\:mode combo.
For example, valid options are: dc10-PAL and buz-NTSC (default: dc10+PAL)
.IPs color|bw
Select color or black and white encoding.
Black and white encoding is faster.
Color is the default.
.IPs hdec={1,2,4}
Horizontal decimation 1, 2 or 4.
.IPs vdec={1,2,4}
Vertical decimation 1, 2 or 4.
.IPs quality=1\-20
Set JPEG compression quality [BEST] 1 \- 20 [VERY BAD].
.IPs fd|nofd
By default, decimation is only performed if the Zoran hardware
can upscale the resulting MJPEG images to the original size.
The option fd instructs the filter to always perform the requested
decimation (ugly).
