We read 2 bytes for 15 out of 16 pixels, therefore we need to
have at least 30 bytes, not 16.

Decoded data is always written in pairs within this decoder.
This fixes writes out of bounds.

Previously, we returned 0, meaning successful decoding but 0
bytes consumed, leading to an infinite loop.

If the input buffer contains more data after the deflate stream,
the loop previously left running infinitely, with inflate returning
Z_STREAM_END.

This avoids setting a negative number of frames, ending up with a
negative average frame rate.

If a zero-length video packet is to be returned, just return
AVERROR(EAGAIN) and switch back to the audio stream.

In lpc_prediction(), we write up to array element 'lpc_order' in
an array allocated to hold 'max_samples_per_frame' elements.

Even if the sample rate is valid, an invalid bitrate could
pass the mode combination test below.

This avoids divisions by zero later (and possibly assertions in
time base scaling), since an invalid rate_flag combined with an
invalid bitrate below could pass the mode combination test.

When av_reallocp fails, the associated variables that keep track of
the number of elements in the array (and in some cases, the
separate number of allocated elements) need to be reset.
Not all of these might technically be needed, but it's better to
reset them if in doubt, to make sure variables don't end up
conflicting.

Also add options for specifying a certificate and key, which can
be used both when operating as client and as server.
Partially based on a patch by Peter Ross.

When passing a dict to the nested protocol, it will consume
the used options from it, so a separate copy needs to be used
when reopening the connection multiple times.

A file containing the trusted CA certificates needs to be
supplied via the ca_file AVOption, unless the TLS library
has got a system default file/database set up.
This doesn't check the hostname of the peer certificate with
openssl, which requires a non-trivial piece of code for
manually matching the desired hostname to the string provided
by the certificate, not provided as a library function.
That is, with openssl, this only validates that the received
certificate is signed with the right CA, but not that it is
the actual server we think we're talking to.
Verification is still disabled by default since we can't count
on a proper CA database existing at all times.

This fixes breakage in a few fate tests on certain setups
(that for some reason didn't break on OS X) after the previous
commit (8812a8057). Currently, some video streams are initialized
in ff_MPV_common_init with width/height set at 0 and only changed
to a proper video size with ff_MPV_common_frame_size_change later.
The breakage was diagnosed by Anton Khirnov.

Qansi-alias worked on 12.x, then caused miscompilation on 13.x, but now
works again passing all FATE tests for icl version 14.

The actual usefulness of the hack is not known, and it does cause
infinite loops with some broken input files.
