See commit a8c2d375ca

MSVC requires an explicit cast from void * to void when applying the
ternary conditional operator to switch between methods that return
void.

This follows the spec definition, and removes a field from the relevant
structs.

KLV length is BER encoded (variable size), but the code assumed the encoding to
always use 4 bytes.

Also rename the function to find_partition_by_absolute_offset to make it clear
offset is absolute.

This affects the following samples:

Some AVPacket->pos values are changed because for frame wrapped tracks we point
to the KLV offset and not the data.

Fixes ticket #7866.

Signed-off-by: James Almer <jamrial@gmail.com>

This reverts nvenc to old behaviour, which in some super rare edge cases
performs better.
The implication of this is that any potential API user who relies on
nvenc cleaning up every frames device resources after it's done using
them will have to change their usage pattern.

That should not be a problem, since pretty much every normal usage
pattern automatically implies that surfaces are reused from a common
pool, since constant re-allocation is also very expensive.

After the commit 9f61abc8111, we can use AVFormatContext.strict_std_compliance
instead of HLSContext.strict_std_compliance to avoid the code redundancy.
