If we ever get a GST_FLOW_EOS from downstream, we might retry
pushing new data. But if pushing that data doesn't return a
GstFlowReturn (such as pushing events), we would end up returning
the previous GstFlowReturn (i.e. EOS).
Not properly resetting it would cause cases where queue2 would
stop pushing on the first GstEvent stored (even if there is more
data contained within).
Using a rate of 1.1 in the test is causing the test to
fail on 32-bit because ceil(1.1 * 10) can round to 12.
Instead use a rate 2.0 that can be expressed as floating
point number and doesn't trigger the problem.

Fixes for gst_segment_position_from_running_time_full() when
converting running_times that precede the segment start (or
stop in a negative rate segment)
The return value was incorrectly negated in those cases.
Add some more unit test checks for those cases, and especially
for segments with offsets.
gst_element_post_message() takes ownership of the message so we need to increase
its refcount until we no longer require access to its data (context_type).

The avg_bitrate is an unsigned int, so the gst_util_uin64_scale() function can't
be used for it, as it expects signed integers for the fraction parts arguments.

And only ever use the non-live values if all pads are non-live,
otherwise only use the results of all live pads.
It's unclear what one would use the values for in the non-live case, but
by this we at least pass them through correctly then.
This is a follow-up for 794944f779, which
causes wrong latency calculations if the first pad is non-live but a
later pad is actually live. In that case the live values would be
accumulated together with the values of the non-live first pad,
generally causing wrong min/max latencies to be calculated.
IDLE probes that are directly called when being added will increase /
decrease the "number of IDLE probes running" counter around the call,
but when running from the streaming thread this won't happen.
This has the effect that when running from a streaming thread it is
possible to push serialized events or data out of the pad without
problems, but otherwise it would deadlock because serialized data would
wait for the IDLE probe to finish first (it is blocking after all!).
With this change it will now always consistently deadlock instead of
just every once in a while, which should make it obvious why this
happens and prevent racy deadlocks in application code.

And make use of it in the typefind element. It's useful to distinguish
between the different errors why typefinding can fail, and especially to
not consider GST_FLOW_FLUSHING as an actual error.

Otherwise downstream will consider the pipeline not live if the active
pad is live, even though some inactive pads might be live and might
require a non-zero latency configuration.

gst_base_transform_transform_caps can return NULL in various conditions
thus we should not treat its result as valid caps.
In all other places NULL is properly handled.
Under MSYS2 glib-mkenums is an executable and has a .exe extension and
the path does not end with "glib-mkenums".
Make the script compare the path without the file extension instead.

Probes were remembering a cookie that was used to check if the probe was
already called this time before the probes list changed. However the
same probes could've been called by another thread in between and thus
gotten a new cookie, and would then be called a second time.

strncpy() is assumed to be for strings so the compiler assumes that
it will need an extra byte for the string-terminaning NULL.
For cases where we know it's actually "binary" data, just copy it
with memcpy.
Fixes compiler warnings with gcc 8.

gst_buffer_list_new_sized(0) will cause an underflow in a calculation
which then makes it try to allocate huge amounts of memory, which
may lead to aborts.

When outputting debug logs on Windows, some sections are protected
with a non-recursive lock. Turns out though that gst_debug_message_get()
might indirectly, via our printf format extensions, call code which
in turn would try to log something when it can't handle something. If
that happens we end up in gst_debug_log_default() again recursively and
try to again take the lock that's already taken, thus deadlocking.
Format the debug message string outside of the critical section
instead to avoid this.

Remove unneeded reapplication of patterns. Besides being
superfluous (gst_debug_reset_threshold already applies
patterns) it was also wrong and didn't stop checking patterns
after the first match (broken in 67e9d139).
Also fix up unit test which checked for the wrong order.
