Instead of having each tracer implement its own parameter parsing,
centralize the handling in the tracer subsystem using GstStructure.
This simplifies tracer implementations and provides a consistent way
to handle properties.
It also allows for much better documentation by forcing tracer object
to expose properties

There is no reason why we should mandate people to "at least" use the static
sink pad. This caused issues, like mandating that it should always have valid
content linked to it (problematic in case of upstream stream changes).
Instead we only use it if it's actually linked to, in which case it gets added
to the list of inputs.
This actually simplifies the code too.

When checking whether a no-longer used output could be re-used for another slot,
we only want to do that for streams which are not still used.
Otherwise we end up potentially re-assigning a demuxer stream to a completely
different one
Furthermore, if we *are* re-using an output slot, indicate what the replacement
GstStream will be so slot matching can work properly (which can happen in the
case of demuxers which add/remove all pads even if only a single one changed)

This relation type define relations between each components of two groups.
First component of first group relate to first component of second group,
Second component of second group relate to second component of second group,
and so on. It's a denser way to express relations in this context.

There was different behaviour if the proxy was configured through
properties or environment. For properties libcurl would be configured
with any auth, but for environment libcurl would default to using basic.
Now any auth is set for both configuration methods.

The Content-Length header would unconditionally be included when the
proxy property was set. This would result in requests with both
Content-Length and Transfer-Encoding header. Now we rely on the
use-content-length property in the proxy case aswell. This also makes
sure that Content-Type is set correctly, since before that would be
skipped if proxy was used.

If a new fragment is added with a valid duration but no offset then the start
offset is set later based on the end offset of the previous fragment. At that
point the end offset of this fragment can also be calculated and not doing so
would give the next fragment the same start offset.

Allow sample rate, number of channels and bps to change and in that case update
the caps accordingly.
Also move (non-fatal) validity checks and storing of the header values outside
the actual parsing once we actually know that a valid frame is available.
And also don't warn on the last frame with fixed block size blocking strategy
that the block size has changed: the last frame is allowed to be smaller.

We get loads of warnings when parsing videos from users:
gsth264parser.c:1115:gst_h264_parser_parse_user_data_unregistered: No more remaining payload data to store
gsth264parse.c:646:gst_h264_parse_process_sei:<h264parse0> failed to parse one or more SEI message
Those are raised because of unregistered SEI without user data.
The spec does not explicitly state that unregistered SEI needs to have
data and I suppose the UUID by itself can carry valuable information.
FFmpeg also parses and exposes such SEI so there is no reason for us no
too as well.

It creates a new structure for passing the codec quality structure at _start(),
where it will be filled. The quality level can be set or changed according
encoder limits.
Later the quality level will be set at _update_session_parameters() and at each
frame encoding. That's why it has to be set at _start().

The algorithm for generating the current slot index is a simple round robin,
nonetheless it's not assured that the next slot index it's not still used by a
still living encode picture.
This new way holds an array with the still living encode pictures and the next
slot index looks for a released index in the array.
Its downside is deallocating a picture need to be removed from the array, so the
helper has to be passed to the uninit() function
