Fixes building for Windows x86 with MSVC using the link libraries distributed with the CUDA SDK.
check_lib2 is required here because it includes the header to get the full signature of the
function, including the stdcall calling convention and all of its arguments, which enables
the linker to determine the fully qualified object name and resolve it through the import
library, since the CUDA SDK libraries do not include un-qualified aliases.
AVFilterLink.frame_count is supposed to count the number of frames
that were passed on the link, but with min_samples, that number is
not always the same for the source and destination filters.
With the addition of a FIFO on the link, the difference will become
more significant.
Split the variable in two: frame_count_in counts the number of
frames that entered the link, frame_count_out counts the number
of frames that were sent to the destination filter.
The test is not supposed to cover audio.
Also, using -vframes along with an audio stream depends on
the exact order the frames are processed by filters, it is
too much constraint to guarantee.
Fixes valgrind warning about "Conditional jump or move depends on uninitialised value(s)"

Also contains the following changes to the library:
- add ff_ prefix to functions
- remove cplusplus defines.
- add FF_ prefix to contants and some structs
- remove true peak calculation feature, since it uses its own resampler, and
af_loudnorm does not need it.
- remove version info and some fprintf(stderr) functions
- convert to use av_malloc
- always use histogram mode for LRA calculation, otherwise LRA data is slowly
consuming memory making af_loudnorm unfit for 24/7 operation. It also uses a
BSD style linked list implementation which is probably not available on all
platforms. So let's just remove the classic mode which not uses histogram.
- add ff_thread_once for calculating static histogram tables
- convert some functions to void which cannot fail
- remove intrinsics and some unused headers
- add support for planar audio
- remove channel / sample rate changer function, in ffmpeg usually we simply
alloc a new context
- convert some static variables to defines
- declare static histogram variables as aligned
- convert some initalizations to mallocz
- add window size parameter to init function and remove window size setter
function
- convert return codes to AVERROR
- fix indentation

It can read less than the requested amount, in which case buf contains
uninitialized data, causing problems like segmentation faults later on.
Also make sure that image->size is positive, so that it can't match a
negative error code.

The secondary compression in Hap is optional, this change exposes that option to
the user as some use-cases favour higher bitrate files to reduce workload
decoding.
Adds "none" or "snappy" as options for "compressor". Selecting "none" disregards
"chunks" option: chunking is only of benefit decompressing Snappy.

Used to facilitate seeking; particularly for HTTP pseudo streaming.
1. read live streaming or file by sequence
2. if use add_keyframe_index option, add a mark flag at the position,
use to insert new context at the last step.
3. add the keyframes *offset* and *timestamp* into a list
4. if use add_keyframe_index option, shift the metadata data from
mark flag offset
5. insert the keyframes *offset* and *timestamp* from the list by
sequence
6. free the list
7. end.
