53d2e8c977 leaks tracer: log alive objects when receiving SIGUSR1
We don't want to automatically catch signals so use an env variable to
enable this feature.

8c7da1d426 adapter: Rename functions and implement new functions, update test
We don't do calculations with different units (buffer offsets and bytes)
anymore but have functions for:
1) getting the number of bytes since the last discont
2) getting the offset (and pts/dts) at the last discont

and the previously added function to get the last offset and its distance from
the current adapter position.

67ae0ad225 adapter: Add methods to query current offset
API: gst_buffer_prev_offset
API: gst_buffer_get_offset_from_discont

The gst_buffer_get_offset_from_discont() method allows retrieving the current
offset based on the GST_BUFFER_OFFSET of the buffers that were pushed in.

The offset will be set initially by the GST_BUFFER_OFFSET of
DISCONT buffers, and then incremented by the sizes of the following
buffers.

The gst_buffer_prev_offset() method allows retrievent the previous
GST_BUFFER_OFFSET regardless of flags. It works in the same way as
the other gst_buffer_prev_*() methods.

1dbb27f3a7 utils: Add gst_pad_link_maybe_ghosting() for consistency
We already had a _full() version, but having that alone seems inconsistent.
Add a non-full version that mirrors the behaviour of gst_pad_link() vs
gst_pad_link_full().

8177173db0 element: Add gst_element_call_async()
This calls a function from another thread, asynchronously. This is to be
used for cases when a state change has to be performed from a streaming
thread, directly via gst_element_set_state() or indirectly e.g. via SEEK
events.

Calling those functions directly from the streaming thread will cause
deadlocks in many situations, as they might involve waiting for the
streaming thread to shut down from this very streaming thread.

This is mostly a convenience function around a GThreadPool and is for example
used by GstBin to continue asynchronous state changes.

f876306638 utils: expose pad_link_maybe_ghosting
This is a useful function to automatically add ghost pads when linking
two elements across bin boundaries without know their exact parentage.

e.g. when using gst_parse_bin_from_description (with or without it ghosting pads),
one can simply retreive the src/sink pads from the bin to link to another pad.

Similar functionality is provided by gst_element_link_pads{_full}() however only
by pad name rather than by actual pads.

API: gst_pad_link_maybe_ghosting_full

fa12d23a17 element: add gst_element_class_add_static_pad_template()
Pretty much every single element does

  gst_element_class_add_pad_template (element_class,
      gst_static_pad_template_get (&some_templ));

which is both confusing and unnecessary. We might just
as well add a function to do that in one step.

778160be08 harness: Add event stress test functions with callback
Similar to the stress test functions for buffers that has a callback to
create the buffer to be pushed, it's useful to have functions that use a
callback to create the event to be pushed.

10b78d872b tracerrecord: add a log record class
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.

Add docs for the new class and basic tests.

Remove the previous log handler.

347734e529 info: expose debugging printf functions
Other gst libraries and/or elements may want to add some debug logging to an

to g_vasprintf if the debug system is disabled.
