Keep on reading fragments until we got fragment_size amount of data, otherwise
we might get frames with 1-2 samples only if pa_stream_peek is called slightly
less frequently than sample rate.
Note that fragments might contain a lot less data than fragment_size, so
reading multiple fragments to get fragment_size amount of data is intentional.

This callback is functionally the same as get_buffer2() is for decoders, and
implements for the new encode API the functionality of the old encode API had
where the user could provide their own buffers.

The top-level GetBitContext is sized for the whole NAL unit, so it fails
to detect overflows where a payload continues into the following message.
To fix that, we make a new context on the stack for reading each payload.

In total, the number of short term references (from the selected short
term ref pic set), the number of long term references (combining both the
used candidates from the SPS and those defined in the slice header) and
the number of instances of the current picture (usually one, but can be
two if current picture reference is enabled) must never exceed the size
of the DPB. This is a generalisation of the condition associated with
num_long_term_pics in 7.4.7.1.
We use this to apply tighter bounds to the number of long term pictures
referred to in the slice header, and also to detect the invalid case where
the second reference to the current picture would not fit in the DPB (this
case can't be detected earlier because an STRPS with 15 pictures can still
be valid in the same stream when used with a different PPS which does not
require two DPB slots for the current picture).

An AVBufferRef (and the corresponding AVBuffer and the underlying actual
buffer) would leak in ff_cbs_sei_add_message() on error in case an error
happened after its creation and before it has been attached to more
permanent storage. Fix this by only creating the AVBufferRef immediately
before attaching it to its intended target position.
(Given that no SEI message currently created is refcounted, the above
can't happen at the moment. But Coverity already nevertheless noticed:
This commit fixes Coverity issue #1473521.)

Setting this field happens immediately after the allocation in
ff_cbs_init(), so the whole CBS code may presume that any
CodedBitstreamContext has this set. Lots of code already presumed this,
yet ff_cbs_close() did it inconsistently: It checked before checking
whether the CodedBitstreamType has a close function; yet it simply
unconditionally read ctx->codec->priv_class. Coverity complained about
this in issue #1473564, which this commit fixes.

If b-frames were enabled implicitly (if max_b_frames wasn't set by
the caller at all, since a0949d0bcb),
we wouldn't offset dts at all, producing invalid pts/dts combinations
(causing loud warnings by ffmpeg, or muxer errors if passed without
an extra cleanup pass).
Instead use frameIntervalP for offsetting, which should always be
accurate.

The uspp filter uses a special option ("no_bitstream") of
the Snow encoder to suppress it from generating output.
The filter therefore did not unref the packet after usage,
believing it to be blank. But this is wrong, as the Snow encoder
attaches quality stats side data to the packet.

This commit adds a "gophers" handler to the gopher protocol. gophers
is a community-adopted protocol that acts the same way like normal
gopher with the added TLS encapsulation.
The gophers protocol is supported by gopher servers like geomydae(8),
and clients like curl(1), clic(1), and hurl(1).
This commit also adds compilation guards to both gopher and gophers,
since now there are two protocols in the file it makes sense to
have this addition.

Beginning with version 3.0, libiLBC switched the types of some parts
of their public API to size_t and renamed some types; the old names
continue to work as typedefs, but are deprecated. It furthermore
added version macros.
This commit uses said version macro to use the new types when using
newer libiLBC versions.
