Change to always include gst/libs/base.h in order to also
include base-prelude.h, but also because it's the right
thing for people to include anyway.

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.

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).

Fixes a configure error with gst-build:
subprojects/gst-plugins-base/meson.build:235:2: ERROR: Fetched variable 'gst_check_dep' in the subproject 'gstreamer' is not a dependency object.
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.
Otherwise we write out the SYNC_AFTER buffer immediately, and the
previously queued up buffers afterwards which then breaks the order of
data.
Also add various debug output.
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.
Make our own deprecation marker for libgstcheck,
since the function declaration must contain the
right API export decorator (GST_CHECK_API) and
not the one for GStreamer core.
Don't return a value from a function that doesn't
return a value using the returned value from a
function that also doesn't return a value.

Otherwise it's not guaranteed that buffers are actually on disk after
pushing them, and reading the file via g_file_get_contents() might not
include them yet.
fflush() has no effect because we use writev() directly, so fsync()
should be used instead which is actually flushing the kernel-side
buffers.
As a next step, a non-line-buffered buffering mode is to be added.

Instead, use -fvisibility=hidden and explicit exports via GST_EXPORT.
This should result in consistent behaviour for the autotools and
Meson builds where this is done already, and will allow us to drop
the win32 .def files.
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.

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.
