Hypothetical Reference Decoding (HRD) model assumes that data flows
into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
Smaller BufferSizeInKB means smaller frame size variations,
but more difficult to maintain HRD.

Additionally:
* Mention that allrgb and allyuv do not support the "size" option.
* Separate examples into subsection.

This reverts commit 590136e78d.
Atomics are not required for this variable, because it is protected
through the lock manager, and the use of atomics here is not compatible
with the c11 emulation wrappersi.
Fixes FATE on MSVC, among other setups which use the compat wrappers.

This fixes the use of old ad-hoc methods which are still supported by some
hwaccels which also support newer methods (DXVA2, VAAPI, VDPAU,
videotoolbox) - without the method being visible here, ff_get_format()
would refuse to use it.

After commit 3701d49 'error_resilience: remove avpriv_atomic usage'
we have included windows.h in much more files and we should
avoid conflicts with defines/function declarations.

The opus.c file uses ff_celt_freq_range and ff_celt_freq_bands which are
defined in opustab.c. The opus parser needs to include that file to
avoid linker errors when not including the opus encoder/decoder.

In commit 061a0c14bb ("decode: restructure the core decoding code"), the
deprecated avcodec_decode_* APIs were reworked so that they called into the
new avcodec_send_packet / avcodec_receive_frame API. This had the side effect
of prohibiting sending new packets containing data after a drain
packet, but in previous versions of FFmpeg this "worked" and some
applications relied on it.
To restore some compatibility, reset the codec if we receive a new non-drain
packet using the old API after draining has completed. While this does
not give the same behaviour as the old API did, in the majority of cases
it works and it does not require changes to any other part of the decoding
code.

Compilation error "out of range" fixed for armeabi-v7a. Compilation failed
trying to build libvlc.aar for ARM7 android on ubuntu 16.04 host. Error
messages is "Offset out of range". The reason of the error is assembler LDR
directives in function "ff_hevc_transform_luma_4x4_neon_8" need local storage
in range <1k, but no such storage provided.
