Since c737f6ed prescreening is
nevertheless run because of a wrong check: "if (s->prescreen > 0)".
s->prescreen is an array of two function pointers that is contained in
the context and comparing it with 0 (i.e. NULL) is actually undefined
behaviour, because NULL and s->prescreen do not point to the same
object (NULL after all never points to any object). Nevertheless both
Clang as well as GCC compile this to code that treat s->prescreen > 0 as
true, leading to segfaults, because the code then tries to access the
-1th member of an array.

This commit fixes the check as well as another such check a few lines
below.

(Found via compiler warnings enabled by -pedantic:
"ordered comparison between pointer and zero is an extension".)

Fixes ticket #9077.

The test should currently fail on big endian but passes because of the
unsuitable input file.

It is a private field that is unused since

Forgotten in 61974537 (notice that
RTPDynamicProtocolHandler is not a public struct, so one can remove
the linked-list pointer immediately (unlike in most other patches of
this kind)).

Fix atoi() overflow for large EXT-X-MEDIA-SEQUENCE.

The spec says the type of sequence number is uint64_t. Use int64_t
here since current implementation requires it to be signed integer,
and hlsenc use int64_t too.

The patch changes the init function to initialize block dimensions to fixed
64x64 instead of the previously used image width/height based value.

This should not cause any actual change in behaviour because block dimensions
are recalculated on every keyframe in optimum_block_width() and
optimum_block_height() functions and in the current code the result is always
64x64 regardless of the image dimensions used.
