407921072f file: fix file_check()
Fixes Ticket1904

This should work on windows, but if not please contact me ASAP
i have another idea on how to solve this without access() if that
really doesnt work on windows.

7709ce029a lavf: avoid integer overflow in ff_compute_frame_duration()
Scaling the denominator instead of the numerator if it is too large

706acb558a h264: enable low delay only if no delayed frames were seen
Dropping frames is undesirable but that is the only way by which the
decoder could return to low delay mode. Instead emit a warning and
continue with delayed frames.
Fixes a crash in fuzzed sample nasa-8s2.ts_s20033 caused by a larger
than expected has_b_frames value. Low delay keeps getting re-enabled
from a presumely broken SPS.

b473c9937e lavu/samplefmt: return the size of the allocated samples buffer at the next bump
Make the functions av_samples_fill_arrays, av_samples_alloc, and
avcodec_fill_audio_frame return a buffer size rather than 0 in case of
success. This will be enabled at the next libavutil major bump, in order
to preserve backward compatibility.

Returning the size allows to simplify the code, avoiding a few function
calls.

e96d90eed6 remove #defines to prevent use of discouraged external functions
Preventing the use of discouraged or 'insecure' external functions
through defines in an internal header is not a good solution. The
header is not guaranteed to be included universally which makes
overlooking bad use of said functions during review more likely.

There are cases were those functions either are the most straight
forward solution or even have to be used. Using malloc or free is
required if the allocation or release is done by other libraries.
