The state of urisourcebin (and all elements contained within) can
change at any point in time, including when setting up the typefind
element.
In order to avoid ending up with typefind starting without being fully
connected, lock the state and connect to the 'have-type' signal.
Sometimes there is a human-oriented timecode that represents an
interval between two other timecodes. It corresponds to the human
perception of "add X hours" or "add X seconds" to a specific timecode,
taking drop-frame oddities into account. This interval-representing
timecode is now a GstVideoTimeCodeInterval. Also added function to add it to
a GstVideoTimeCode.

Due to the special nature of adaptivedemux, reconfigure happens
frequently with seek/track-change.
In very exceptional cases, the following sequence is possible:
* EOS event is pushed to queue element and still buffers are queued
* During draining remaining buffers, reconfiguration downstream
happens due to track switch.
* The queue gets a not-linked flow return from downstream
* Because the sinkpad is EOS, the queue registers an
error on the bus, causing the pipeline to fail.
Avoid the sinkpad getting marked EOS in the first place, by using a
custom event in place of EOS.

It is often usefull to make sure that you get a full copy of a profile.
For example you want to let the user modify it in the user interface
but still keep an unchanged version for later use.
API:
gst_encoding_profile_copy
Generating those files is useful for users building the GStreamer stack
using meson and having to link it to another project which is still
using the autotools.

When shutting down decodebin2 and parsebin, they set their
output pads to flushing, and there is a very small window
where elements might send a sticky event such as a tag event
(which silently fails due to flushing) and then sends a buffer,
and the buffer will return GST_FLOW_ERROR because it can't
forward sticky events. The element will then send an error
message on the bus. This can also happen when elements send EOS
just as shutdown is happening. Since we're about to destroy all
the elements inside parsebin and decodebin anyway, just discard
error messages from them.
A nicer but more difficult fix for GStreamer 2.0 is to make
all event pushing / handling in core return a GstFlowReturn
like buffers do, so we can report a FLUSHING state cleanly.
Initialize min and max _get_property() to gets rid of these
compiler warnings:
gstappsrc.c:741:7: error: 'max' may be used uninitialized in this function
g_value_set_int64 (value, max);
^
gstappsrc.c:733:7: error: 'min' may be used uninitialized in this function
g_value_set_int64 (value, min);
^
Which happens because gcc doesn't know that GST_IS_APP_SRC will never
fail here.

This way special characters such as '@' can be used in
usernames or passwords, e.g.
rtsp://view:%40dm%4An@<IP-ADDR>/media/camera1
will now parse username and password into:
User: view
Pass: @dm:n

When parsing NUL-terminated strings, do not include the terminating
NUL byte(s). Depending on the encoding used, either g_utf8_validate()
failed due to this, or worse the call to g_utf16_to_utf8() would
return 0 items read on an empty string, causing it to fail parsing
certain frames.

cc1: all warnings being treated as errors
Instead of enforcing the user to know and understand caps to describe
the encoding format, let him use element factory names directly.
This also makes it possible to ensure that a specific encodore/muxer
is used instead of letting the ranking system do it.
It is now possible to describe an encoding format simply specifying:
matroskamux:x264enc:vobisenc
Factor out functions in the parsing, cleaning up the whole thing.
Update documentation.
