g_alloca() is not RT-safe, so instead we should allocate the
memory needed in advance. Fixes #655866

Jack 1.9.7 was released 20.Mar.2011, need to handle the deprecated api for this
version too.

95446226 checked
for 0.120.2 and later, but the deprecation was introduced in
0.120.1

jack_port_get_total_latency() has been deprecated in favor of
jack_port_get_latency_range().

https://bugzilla.gnome.org/show_bug.cgi?id=644477

Because we can (shouldn't be needed with other workarounds still there).

Canonicalize property names as needed.

Add dispose methods to clear caps.

Not only adjust buffer-time and avoid segtotal=0, but instead ensure segtotal is
atleast 2. Do same change on jacksrc. We could also check the latency and buffer
time configured by the client and adjust buffer-time so that we get to the same
number of segments.

Jack overrides user-specified latency-time with the one it gets from jack
itself. It also needs to adjust buffer-time somewhat to avoid segtotal being 0

The gst_jack_audio_client_set_active() flags the port as deactivating and uses
a GCond to wait until the jack_process_cb() has run once more and cleared the
flag. This way the client zero's the buffer. This happens if one manyally go
to PAUSED and then to READY, while leting the mainloop run inbetween.

Add a new connection mode to jacksrc and jacksink. In this new auto-force
connection mode jack will create as many ports as requested/needed in the
pipeline and will then connect as many physical ports as possible, possibly
leaving some ports unconnected.

Also get rid of some leftover g_print.

Fixes #575284.
