Fixes: Null pointer dereference

Fixes: CVE-2017-9608
Found-by: Yihan Lian
Signed-off-by: NMichael Niedermayer <michael@niedermayer.cc>

Given how incredibly limited the official specifications are (limiting all use
to only the most common broadcasting formats), permit all supported inputs
by default. This makes the encoder more useful.

Each frame is now padded with 0 values if not enough samples are
present, and all frames are guaranteed to have exactly
1 << (venc->log2_blocksize[1] - 1) samples.

Usage of blocksize, window, mode, and mdct indexes are switched from
default 0 to a default of 1 to better align with specs. A flag of 0
should correspond with short windows, a flag of 1 with long.

Audio samples are shifted around when copying from the frame queue so that
analysis can be done without negatively impacting calculation of the MDCT.

Window coefficients are applied to the current two overlapped windows
simultaneously instead of applying overlap for the next frame ahead of time.
This improves readability when applying windows of varying lengths.

Fixes ticket #6356.

(cherry picked from commit 66aa9b94)

This is something of a hack.  It allocates a new hwframe context for
the target format, then maps it back to the source link and overwrites
the input link hw_frames_ctx so that the previous filter will receive
the frames we want from ff_get_video_buffer().  It may fail if
the previous filter imposes any additional constraints on the frames
it wants to use as output.

(cherry picked from commit 81a4cb8e)

Also refactor a little and improve error messages to make failure
cases easier to understand.

(cherry picked from commit 38cb05f1)

Use the flags argument of av_hwframe_ctx_create_derived() to pass the
mapping flags which will be used on allocation.  Also, set the format
and hardware context on the allocated frame automatically - the user
should not be required to do this themselves.

(cherry picked from commit c5714b51)

(cherry picked from commit e1c5d56b)

Factorises out existing surface initialisation code to reuse.

(cherry picked from commit eaa5e071)

Some frames contexts are not usable without additional format-specific
state in hwctx.  This change adds new functions frames_derive_from and
frames_derive_to to initialise this state appropriately when deriving
a frames context which will require it to be set.
