Buffer pool is created every time setcaps() is called, but it's
required only when upstream doesn't use it, so it's only needed to
copy frames onto XV buffers.
This patch delay the creation of the buffer pool until it's frame copy
is required.

uridecodebin assumes that refcount of decodebins stored in pending_decodebins
are floating but it might not be true in case that refcount of the decodebin
was touched in other places. To avoid the floating refcount issue,
hold strong reference.

Lookup will now maintain the full list of possible IP address(es).
We can now iterate over all available addresses in case certain
address families (IPv6) are disabled or try connecting to additional
addresses for the clients.

`@` references are used to reference function parameters, struct members
or enum variants _within_ the current type/function. It cannot and
should not be used to reference to types outside that.
Since C has no notion of member functions it makes little sense to
prefix these with `@`; most of the documentation here was referencing
functions on _different_ types anyway.

Like other foobarA variant APIs on Windows, formatted string
by strftime() is ANSI string, not unicode encoded one.
It would be problematic for non-english locale systems.
We should use unicode version API (wcsftime in this case)
whenever it's possible on Windows.

If the alsasink thread starts the write loop but another thread pauses
the underlying alsa device, the sink thread will endlessly loop.
snd_pcm_writei() will return 0 if the state is SND_PCM_STATE_PAUSED
and the loop will never make any progress.

Table 1.10 – "Levels for the AAC Profile" only goes to 5 max channels
/ 7 max channel post amendmend, so I assume the number of channels
should not include LFE, otherwise there's no valid level for 5.1 resp.
7.1 (post amendmend)

e.g. if we have:
video-x/raw,format=I420 ! compositor ! video/x-raw,format=BGRA
This will currently produce a warning as the alpha-ness of the chosen
'best' format (I420) will be different from the value restricted by the
downstream caps filter.

When adding inputs dynamically, we need to make sure the new parsebin are
added *and* activated by the same thread (by taking the state change lock).
The rationale for this is that the calling thread might be an upstream streaming
thread and when activating parsebin it might call back upstream. If we don't use
the same thread (ex: when the application does a state change on decodebin3
between the moment we add parsebin to decodebin3 and we synchronize the state of
parsebin) then we would end up in different threads trying to take upstream
recursive locks.
