This reverts commit 3fc08304.
The revert is done because the reasoning behind the commit was
flawed, closed_gop is not mpeg1/2 specific.

In particular, fix sliding color bar with padded data, for example with
testsrc,pad=iw+200:ih.

This filter does not support slice-drawing, the whole blurred image needs
to be written in end_frame().

Code is about 2x as fast as previous

This fixes assembling using "nasm".

for example:
Attempting to set ac3 dsur_mode to "on" results in:
[AC-3 Encoder @ 0x7f508f0a3280] Value 2.000000 for parameter 'dsur_mode' out of range
[AC-3 Encoder @ 0x7f508f0a3280] Error setting option dsur_mode to value on.

It's not used anywhere else.

It's MPEG-1/2 specific.

It's MPEG-1 specific.

It will be used in vdpau code.

This also fixes that sometimes a frame would actually not be freed.

This allows commands of the form "make foo.s", which is useful
for inspecting the compiler output for debugging purposes.
