a19497ab67 appsrc/sink: Fix optimization for only signalling waiters if someone is actually waiting 
It is possible that both application and the stream are waiting
currently, if for example the following happens:
  1) app is waiting because no buffer in appsink
  2) appsink providing a buffer and waking up app
  3) appsink getting another buffer and waiting because it's full now
  4) app thread getting back control

Previously step 4 would overwrite that the appsink is currently waiting,
so it would never be signalled again.

4fe5178957 appsrc: don't signal the GCond if no one is waiting on it 
Performance optimisation: Keep track whenever the streaming
thread or the application thread are waiting on the GCond for
more space or new data, and only signal on the GCond if someone
is actually waiting. Avoids unnecessary syscalls and thus
context switches.

5a5a1f0dc6 appsrc: use GstQueueArray instead of GQueue for internal item queue 
Performance optimisation.

Avoids alloc/free churn for the queue's list nodes.

Depends on new API in GstQueueArray in core.

57ff3ea72f appsrc: fix compiler warning 
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.

d43f1b2a5a appsrc: Clear is_eos flag when receiving the flush-stop event 
The EOS event can be propagated to the downstream elements when
is_eos flag remains set even after leaving the flushing state.
This fix allows this element to normally restart the streaming
after receiving the flush event by clearing the is_eos flag.

bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs

also just not very accurate. Seeing 'last reviewed: 2005' in

those comments.
