9251cd9bf5 gst: skip format specifiers from gir generation
GST_TIME_FORMAT, GST_TIME_ARGS, GST_STIME_FORMAT, GST_STIME_ARGS
GST_PTR_FORMAT, GST_SEGMENT_FORMAT, GST_FOURCC_FORMAT and
GST_FOURCC_ARGS are format specifiers.
They can't be used outside of C and should be generated in the gir.

8983cce9f6 gst: GST_EXPORT -> GST_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

ad0dd860c9 debug: Add a memory ringbuffer based debug logger
This stores debug logs in memory per thread and uses up to a
configurable amount of bytes per thread for the logs. Inactive threads
are timed out after a configurable amount of time.

33616d47be info: Add a 'flags' parametter to gst_debug_get_stack_trace
This is an API break but that API has not been released yet.

We are passing a flag rather than a simple boolean as we can imagine
to implement more features in the future for example to retrieve a
stack trace for all the threads, etc..

Retrieving source file and line numbers is pretty
expensive while getting a stack trace, this new argument
allows the user to decide to retrieve a backtrace
without those infos instead which is much faster.

For example running $ GST_LEAKS_TRACER_STACK_TRACE=1 GST_DEBUG=GST_TRACER:7 \
GST_TRACERS=leaks time gst-launch-1.0 videotestsrc num-buffers=1 ! fakesink:

* With simple stack traces:

    0.04s user 0.02s system 99% cpu 0.060 total

* With full stack traces:

    0.66s user 0.23s system 96% cpu 0.926 total

347734e529 info: expose debugging printf functions
Other gst libraries and/or elements may want to add some debug logging to an
external debug system or implement delayed debugging for performance reasons.

Exposes the internal __gst_vasprintf as gst_info_vasprintf which has a fallback
to g_vasprintf if the debug system is disabled.

7e2aae7942 info: fix compiler warning with -Wpedantic and gcc 5
Gstreamer compiled with gcc 5.2 and -Wpedantic produces the
following warning:

'ISO C does not support '__FUNCTION__' predefined identifier [-Wpedantic]
  const char *s = __FUNCTION__;'

Since gcc 5 enables C99 by default, use __func__ if it's available
instead of the non-standard __FUNCTION__ (as suggested in [2]).

d92e18b722 gstinfo: Add new maximum level debugging
API: GST_LEVEL_MAX

By compiling gstreamer (or plugins) with GST_LEVEL_MAX defined, only
the debugging statements at or below that level will be compiled in.

This allows compiling in some debugging (like errors and warnings) which
helps in debugging, but without the full cpu/memory overhead of all debugging
enabled.

fe7f7135e0 printf: add infrastructure for pointer extensions hook
Does not do anything yet. On a sidenote, we can't just use
%p\001 or so to signal the extension because g-i complains
about an invalid ascii character then, so have to resort to
something more elaborate, such as %p\aA etc.

ac40ab45b3 info: make _gst_debug_init() private for now
This was a FIXME for 0.11. I guess a case could be made to keep it around
separately for apps or libraries that only want to use GStreamer's debugging
system, but it seems more likely they'd just copy the two source files into
their own tree if the case. Also, things like types wouldn't be initialised
without gst_init(). We can still make it public again if anyone needs it,
but then we should make it a proper function and not hide it behind
underscores.

609a75eae2 info: make adding/removing of gst_debug_log_default() work properly
Make adding/removing gst_debug_log_default() work reliably in all
circumstances. The problem was that depending on platform and linker
flags the function argument might resolve to different addresses,
which made it impossible to remove the default log function added
in gst_init() from application code (because the pointer values
didn't match). The new approach should keep things simple by passing
NULL for the default function, which the code in libgstreamer can
then handle.

66fc4c8ba2 info: add new TRACE log level and move refcounting there from LOG level
This makes it possible to easily get a *:5 debug log without all
the refcounting noise, and drastically reduces the number of lines
output for a normal log (46m to 28m for a 20min video). The full log
including refcounting information can still be gotten using *:7.

Fixes #620460.
