Treat all '*.pnm' files as non-text file

This convinces the pre-receive hook to not consider all *.pnm files as
text files to reduce the patch sizes and avoids triggering whitespace
checks,

avfilter/vf_yadif: fix extra leading dup frame when deint=1

Logic for handling single frame in yadif (0f9f24c9), caused deint=1 (e.g., yadif=0:-1:1) to output extra duplicate leading frame:

ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm  -vf yadif=0:-1:1,showinfo -f null -y /dev/null
 [Parsed_showinfo_1 @ 0x1d967d0] n:0 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]
 [Parsed_showinfo_1 @ 0x1d967d0] n:1 pts:0 pts_time:0 pos:-1 fmt:gray sar:0/1 s:352x432 i:P iskey:1 type:I checksum:E457EEA0 plane_checksum:[E457EEA0] mean:[126] stdev:[46.6]
(Outputs 51 frames)

After patch, vf "yadif=0:-1:1" behaves correctly (like "yadif=0:-1:0") and outputs 50 frames, first two:

(Outputs 50 frames)

ffmpeg: take bsf arguments from the command line

The format is now:
-bsf:X filter1[=opt1=str1/opt2=str2],filter2
ie the parameters are appended after the filter name using '='. As ','
has been reserved already for the list of filters, '/' is just an
example of token separation for now, but that could become part of the
API to avoid each bsf using its own tokenization.

The proper solution would be using AVOption, but this is overkill for now.
