a4a1782872 tracer: Add new tracer to list loaded elements and other features
This new tracer will list loaded elements and plugins. This should
make it easier to generate minimal builds of GStreamer.

This also traces other features such as typefind functions, device
providers and dynamic types.

The format of the output of gst-stats should match the parameters
expected by the meson based gst-build system.

ef0df31c5e gst-stats: Fix missing NULL checks
gst-inspect-1.0 segfaults on tracing logs where it fails to find
element stats. So on the pipelines where we get the following WARNING
during execution will afterwards crash with a segfault as the
g_ptr_array has a index for it but it is just a NULL pointer.

WARN default gst-stats.c:444:do_message_stats: no element stats found for ix=X

An example of an pipeline which can reproducibly create a trace log
where this occurs would be this

GST_DEBUG="GST_TRACER:7" GST_TRACERS="stats;rusage;latency" gst-launch-1.0 videotestsrc num-buffers=120 ! autovideosink &> trace.log
gst-stats-1.0 trace.log

e9085043c1 Don't use glib format modifiers with sscanf or printf
We do not have a way to know the format modifiers to use with string
functions provided by the system. `G_GUINT64_FORMAT` and other string
modifiers only work for glib string formatting functions. We cannot
use them for string functions provided by the stdlib. See:
https://developer.gnome.org/glib/stable/glib-Basic-Types.html#glib-Basic-Types.description

F.ex.:

```
 ../tools/gst-stats.c:921:11: error: too many arguments for format [-Werror=format-extra-args]
   printf ("Number of Buffers passed: %" G_GUINT64_FORMAT "\n", num_buffers);
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../tools/gst-stats.c:922:11: error: unknown conversion type character 'l' in format [-Werror=format=]
   printf ("Number of Events sent: %" G_GUINT64_FORMAT "\n", num_events);

71f1b5ec83 gst-stats: sort latency by first activity before displaying
We use to display the latency of each element in random order which is
not very convenient when comparing latency between different runs.
Sort them by "first activity" (the first latency reported for each
element) so it's consistent betwen runs.

This is the same logic when sorting and displaying element stats.

ab60a330db gst-stats: format latency as GST_TIME
Latency is easier to read when formatted as time rather than displayed
as a flat number in ns.
Especially when displaying GST_CLOCK_TIME_NONE which is now formated as
99:99:99.999999999 instead of 18446744073709551615.

e615a3ddee gst-stats: Add element latency support
This will output latency information when parsing a log file with gst-stats that
has latency trace information. It will show the min, max and mean latency for
the pipeline and all its elements. It will also show the reported latency for
each element of the pipeline. Output example:

Latency Statistics:
	pulsesrc0_src|fakesink0_sink: mean=190000043 min=190000043 max=190000043

Element Latency Statistics:
	flacparse0_src: mean=45561281 min=654988 max=90467575
	flacenc0_src: mean=89938883 min=81913512 max=97964254
	flacdec0_src: mean=45804881 min=228962 max=91380801

Element Reported Latency:
	pulsesrc0: min=10000000 max=200000000 ts=0:00:00.262846528
	flacenc0: min=104489795 max=104489795 ts=0:00:00.262898616
	flacparse0: min=0 max=0 ts=0:00:00.262927962

f37688ef4d tools: gst-stats: Use standard character escapes
Having '\e' expand to '\x1b' is a gnu extension. I didn't see any
document describing the behavior, but gcc also seems to expand
'\[' to '['.
