ce482266a6 avcodec/alacenc: Don't free unnecessarily 
The init function of the ALAC encoder calls its own close function
if a call to ff_lpc_init() fails; yet nothing has been allocated before
that point (except extradata which is freed generically) and ff_lpc_init()
can be expected to clean up after itself on error (the documentation does
not say anything to the contrary and the current implementation can only
fail if the only allocation fails, so there is nothing to clean up on
error anyway), so this is unnecessary.

e36db49b7b avcodec: Add a min size parameter to ff_alloc_packet2() 
This parameter can be used to inform the allocation code about how much
downsizing might occur, and can be used to optimize how to allocate the
packet

d6604b29ef Gather all coded_frame allocations and free functions to a single place 
Allocating coded_frame is what most encoders do anyway, so it makes
sense to always allocate and free it in a single place. Moreover a lot
of encoders freed the frame with av_freep() instead of the correct API
av_frame_free().

This bring uniformity to encoder behaviour and prevents applications
from erroneusly accessing this field when not allocated. Additionally
this helps isolating encoders that export information with coded_frame,
and heavily simplifies its deprecation.

Otherwise it is not needed because it matches the frame size as encoded in
the extradata.

ba821b098b alacenc: store current frame size in AlacEncodeContext. 
This avoids an indirection and will simplify implementation of encode2()

302daf5800 alacenc: calculate a new max frame size for the final small frame 
Gives a better estimate of buffer requirements and a better decision of
whether or not to use verbatim mode.
