This patch fixes a problem that occurs at the start of playback of MPEG2
streams.  The symptom is that an initial good frame will display and
then the video appears to skip back a frame or two and some
macroblocking is observed. The stream then plays correctly. This is
really obvious when switching between SAPed multicast streams, where
you're jumping right in to a lot of movement and probably not starting
with an I frame.

The issue appears to be some code introduced way back in 2004 (commit
eaefb850) which resubmits data to the
video codec. The commit notes suggest it was to avoid dropping the first
I frame, but I see no obviously lost I frames after removing the code
with my test samples. Presumably this was a work-around for a libavcodec
issue that is no longer required.

Therefore, this patch basically just reverts the 2004 commit in its
current form.

Also fix potential buffer overflow with snprintf().

Those values are already set by the caller function.

The content view can never be nil, so methods like removeFromSuperView
which are used do not work as expected. Thus, it was possible that the
content view is a dangling pointer, causing crashes when trying to draw
the window.

This fixes several glitches like concurent animation of window resize
and fullscreen resize.

This also removes old workarounds which are not needed anymore.

close #10826

This should not be needed anymore.

Sometimes GF_INERTIA is caught too, for example

This eliminates the inconsistency between the equalizer bands that are
portrayed by the API and the bands that are actually used by the equalizer
module.

To ensure the vdp_t instance pointers comparison is valid, the old and
new instances must be contemporary. Otherwise, the heap could put both
instances at the same memory address. So keep a reference to the old
device until after the comparison.
