* commit '44129e38':
  avconv: Do not pass NULL to avio_tell

This commit is a noop. The FFmpeg code handle cases where total_size is
an AVERROR (which avio_tell(NULL) will return) later in the function.

Note: the original commit refers to the null *muxer*. `ffmpeg -lavfi
testsrc -f null -` can be used as a test case.

Add dxva2_pool_release_dummy() and use it in call to
av_buffer_create() in dxva2_pool_alloc().

Prior to this change, av_buffer_create() was called with NULL for the
third argument, which indicates that av_buffer_default_free() should
be used to free the buffer's data.  Eventually, it gets to
buffer_pool_free() and calls buf->free() on a surface object (which is
av_buffer_default_free()).

This can result in a crash when the debug version of the C-runtime is
used on Windows.  While it doesn't appear to result in a crash when
the release version of the C-runtime is used on Windows, it likely
results in memory corruption, since av_free() is being called on
memory that was allocated using
IDirectXVideoAccelerationService::CreateSurface().

Enables rendering of SVG images. This is possible since SVG images
still contain and specify the dimensions in pixels to which they've
been drawn to and thus enable browsers to display them without any
external data. Users can still override and generate images with
arbitrary resolutions.

Old behaviour - abort if at least one subband has 1bit quantizer
and consumed_bits still greater than frame_bits size. It was
a bit strange - we still could reduce bits consumption by reducing
SNR for other subbands. Same strange logic with upper threshold -
stop bits allocation if at least one subband reach 26bits.

New behaviour - if consumed_bits greater than frame_bits and all
subbands has 1 bit quantizer we restart bits allocation and allow
zero subbands.
