As I used simple RGBA formats for subtitles and for the video texture if
avfilter is disabled I kind of assumed that sws_scale won't access data
pointers and strides above index 0, but apparently that is not the case.
Fixes Coverity CID 1396737, 1396738, 1396739, 1396740.

Insertion of silence was a bit broken since
df34b70098 because the info whether or not the
source buffer supposed to be silence must be kept between callbacks. Failing to
do so causes rogue samples from the last buffer to be presented, I guess even a
crash can occur under some circumstances.
This patch uses a NULL audio_buf to keep the silence state across audio
callbacks.

Now that the seek only happens with the right mouse button, it makes
sense to toggle full screen when double-clicking with the left mouse
button, like other video players do.

Seeking by clicking on the video window can be annoying, because
the user might click on it accidentally while eg. trying to get
focus on it, and ffplay seeks instead.
This commit changes that behaviour to seek only when the right
mouse button is used to click and drag on the window.

This reverts commit 9cc1e644f3.
avoids the float to integer cast, and is slightly superior in terms of
rounding ("Dutch/Gauss rounding").

Current code segfaults since the deprecation of AVSubtitleRect.pict because it
freed/realloced AVSubtitleRect.pict.data by itself.
The new code stores the generated YUVA AVSubtitle rectangles in their own
struct and keeps the original AVSubtitle structure untouched, because
overwriting it is considered invalid API usage.

This is a feature heavily inspired by the mpv player. At the moment, methods
for adjusting volume in ffplay are rather clumsy: either one needs to set it
system-wide, or one needs to set it via the volume filter.
This patch adds key bindings identical to the mpv defaults for muting/unmuting
and increasing/decreasing the volume interactively without any introduction of
external dependencies.
TODO: doc update, possible mouse button bindings (mpv has this).

filename was set to an arbitrary 1024 characters. ffplay would thus be unable to
play files whose name exceeds that arbitrary threshold.
This patch dynamically allocates and frees the filename buffer to remove such
limitations.

Key repeats have been introduced simply because they improve usability in my
experience for volume, brightness, and other such controls by speeding up the
time taken to go from 0 to max intensity. As a side benefit, this enables rapid
seeking through a file via left/right keys.

The amv one probably looks suspicious, but since it's an intra-only
codec, I couldn't possibly imagine what it would use the edge for,
and the vsynth fate result doesn't change, so it's probably OK.
FFplay was using a 5 frame packet buffer, this is not much (e.g. 200 ms for
25fps video), when HLS is requesting a new segment via HTTP, it may take longer
for the request to complete.
Should fix ticket #4720.

The windows SDL audio driver plays the old data in the buffer in a loop if it
is not updated in time. So instead of waiting for data and blocking the the
audio thread, return silence if no data is available.

Fixes some files from Ticket679
This also changes subtitles to 4:2:0 matching the output format and thus
simplifying the blend code.
This restricts placement to the chroma sample resolution though, speak up
if you consider this a problem, say so, the code could be changed to use
YUV444 for subtitles and scaling them down while blending, this would be
slower though.
The current code only uses a single swscale context and reinitializes it
as needed, this could be changed as well if needed
