android_get_device_api_level() is a static inline before API level
29. It was implemented via __system_property_get(). We can do the
same thing, but I don't want to mess up with __system_property_get.

There is no reason to enforce a high minimum. In the context
of streaming only a few output buffers and capture buffers
are even needed for continuous playback. This also helps
alleviate memory pressure when decoding 4K media.

The cached bitstream reader was originally written by Alexandra Hájková
for Libav, with significant input from Kostya Shishkov and Luca Barbato.
It was then committed to FFmpeg in ca079b0954, by merging it with the
implementation of the current bitstream reader.
This merge makes the code of get_bits.h significantly harder to read,
since it now contains two different bitstream readers interleaved with
#ifdefs. Additionally, the code was committed without proper authorship
attribution.
This commit re-adds the cached bitstream reader as a standalone header,
as it was originally developed. It will be made useful in following
commits.

Current code stores a pointer to allocated data in libx265 and frees it
when the encoded packet is retrieved. This will leak if the packet is
never retrieved, e.g. if the encoder is closed without being flushed.
Restructure the code such that only indices to an array stored in our
private data are given to libx265. This ensures no allocated memory can
be lost.

Similar to how the encoder looks at frame color information to write the frame
header bitstream.
Should workaround ticket #10091, where container level color parameters passed
to the decoder context were being overwritten.

PFM (aka Portable FloatMap) encodes its scanlines from bottom-to-top,
not from top-to-bottom, unlike other NetPBM formats. Without this
patch, FFmpeg ignores this exception and decodes/encodes PFM images
mirrored vertically from their proper orientation.
For reference, see the NetPBM tool pfmtopam, which encodes a .pam
from a .pfm, using the correct orientation (and which FFmpeg reads
correctly). Also compare ffplay to magick display, which shows the
correct orientation as well.
See: http://www.pauldebevec.com/Research/HDR/PFM/ and see:
https://netpbm.sourceforge.net/doc/pfm.html for descriptions of this
image format.

EAGAIN is not correct in this scenario. FFCodec.cb.decode() callback decoders
always return the amount of bytes consumed from the input packet (if any), and
report if a frame was generated by setting got_frame.

Add encoding of 32 bit-per-sample PCM to FLAC files to libavcodec.
Coding to this format is at this point considered experimental and
-strict experimental is needed to get ffmpeg to encode such files.
