max_buffer_usage is the index of the oldest buffer in the queue,
starting at zero, not the number of buffers queued.
find_limits returns the index of the oldest buffer that satisfies the
limits in its min_idx parameter, not the number of buffers needed. Fix
this use too in order to keep passing the tests that read
buffers-queued.

If a client gets dropped and the iteration gets restarted, bufpos is
incremented again for all clients that preceded the dropped one, causing
havoc.
Adjust the bufpos for all clients first before trying to drop any.

The flags and field order weren't properly initialized in the
gst_video_info_init().
Furthermore in gst_video_info_from_caps() we might set unitiliazed
values previously, this only sets them if valid.
Optimize LE<->BE conversion by adding a dedicated fast path instead of
using the generic converter. Implement transform_ip function in order to do the
endian swap in place.
This saves buffer allocation for the intermediate format, can be done in place
and also performs the conversion in one step instead of unpack-convert-pack.
For all bit widths the naive algorithm is implemented, which provides the best
performance when compiled with -O3. ORC was considered but eventually removed
as it requires a dedicated function for in-place conversion (due to the
"restrict" parameters).
A more complex algorithm for the 24-bit conversion with unrolled loop and
32-bit processing is implemented in the #if 0 section. It performs better if
compiled with -O2. With -O3 however the naive algorithm performs better.

It is not needed to store a pointer to every single chain element to free it.
Instead walk the channel list backwards and free the chain elements one by one.
Rename GstAudioConverter->chain_pack to chain_end.

The caps might not be fixated (which is required by GstVideoInfo) and we
would assert otherwise. However the caps often contain useful
information in the already-fixed parts that we can use here.
For frame->buffer, baseparse is doing that automatically for us. For
frame->output_buffer it doesn't and assumes that the subclass is already
doing that. Consistency!
When gst_rtp_buffer_add_extension_onebyte_header() is used over a
GstRtpBuffer that only contains a memory for the whole packet,
ensure_buffers function crashes at the next point:
mem = gst_memory_copy (rtp->map[i].memory, offset, rtp->size[i]);
when i==2 because the payload is not mapped.
In addition the offset is calculated subtracting in the wrong direction.

For example mmap can fail with EACCES if the the fd has been open
with read only mode. And mapping the memory might be the only way
to check that. So no need to print out an error.
Ex: ioctl(dev, DRM_IOCTL_PRIME_HANDLE_TO_FD, flags & ~DRM_RDWR)

This class was made subclassable, though for future growth of the code,
it's better if we have some room for add class members. Using the small
padding since this is unlikely.
For drop-frame timecodes, the nsec_since_daily_jam doesn't necessarily
directly correspond to this many hours/minutes/seconds/frames. We have
to get the frame count as per frames_since_daily_jam and then convert.

Rename function parameter and make sure the name in the
declaration matches the name in the implementation, to
avoid g-i warnings. Also add Since markers for gtk-doc.
