It is now set generically for all those encoders whose corresponding
AVCodecDescriptor has the AV_CODEC_PROP_INTRA_ONLY.

Up until now, ff_alloc_packet2() has a min_size parameter:
It is supposed to be a lower bound on the final size of the packet
to allocate. If it is not too far from the upper bound (namely,
if it is at least half the upper bound), then ff_alloc_packet2()
already allocates the final, already refcounted packet; if it is
not, then the packet is not refcounted and its data only points to
a buffer owned by the AVCodecContext (in this case, the packet will
be made refcounted in encode_simple_internal() in libavcodec/encode.c).
The goal of this was to avoid data copies and intermediate buffers
if one has a precise lower bound.
Yet those encoders for which precise lower bounds exist have recently
been switched to ff_get_encode_buffer() (which automatically allocates
final buffers), leaving only two encoders to actually set the min_size
to something else than zero (namely aliaspixenc and hapenc). Both of
these encoders use a very low lower bound that is not helpful in any
nontrivial case.
This commit therefore removes the min_size parameter as well as the
codepath in ff_alloc_packet2() for the allocation of final buffers.
Furthermore, the function has been renamed to ff_alloc_packet() and
moved to encode.h alongside ff_get_encode_buffer().

Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

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.

This allows a subsequent change to compress directly into the output packet when possible.

"Vidvox Hap", not "Vidvox Hap encoder" or "Vidvox Hap decoder". Fixes
bad name in "ffmpeg -codecs", matches other codec naming.
