Fixes a bogus compiler warning (max_samples_per_frame is checked):
libavcodec/alac.c: In function ‘allocate_buffers’:
./libavutil/internal.h:142:9: warning: argument 1 value ‘18446744073709551552’ exceeds maximum object size 9223372036854775807
The spec defines it as an array of signed values, inferred to 0 when not
present.

Cleanup the applehttp as demuxer name, when use the command :
ffmpeg -formats, get the confused information like:
"
E hls Apple HTTP Live Streaming
D hls,applehttp Apple HTTP Live Streaming
"
we don't use applehttp as the demuxer/muxer name usually, so
cleanup the applehttp and update the documents.
After the change, get the information from "ffmpeg -formats":
"
DE hls Apple HTTP Live Streaming
"

This is a low speedup, but the x86 mmx version also gets only ~2x. The mmx version
is also heavily inaccurate, while the vsx version has high accuracy.
