af91d23204 tracer: use the new flags to create the optional field in the format string
This spares us explicitly listing the field in the spec. and thus hide this
implementation detail.

8b88fc487f gst.h: Don't spew warnings if GST_USE_UNSTABLE_API is not defined
Only hide GstTracer and GstTracerRecord API behind GST_USE_UNSTABLE_API,
but don't spew any warnings, otherwise everyone has to define this
to avoid compiler warnings.

This reverts parts of commit 89ee5d948d.

89ee5d948d tracer: add a GFlag for the tracer scope

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.

4d6c7ccd08 GstDeviceMonitor: Don't remove unmatched class filters
If no providers for a particular class could be found, then removing unmatched
filters would cause all devices to be returned instead which is not at all what
the user intended. We still return 0 for unmatched filters.

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.

API: gst_info_vasprintf
API: gst_info_strdup_vprintf
API: gst_info_strdup_printf

46a851b279 parse-launch: warn when still waiting to plug sub-pipelines after no-more-pads
The parse-launch API automagically handles dynamic pads and performs delayed
linking as needed, without any feedback about whether the linking succeeded or
not however. If a delayed dynamic link can't be completed for whatever reason,
parse-launch will simply wait in case a suitable pad appears later. This may
never happen though, in which case the pipeline may just hang forever.

Try to improve this by connecting to the "no-more-pads" signal of any element
with dynamic pads and posting a warning message for the related outstanding
dynamic links when "no-more-pads" is emitted.

b427997119 element: Don't hold state lock all the time while sending an event
This lock seems to exist only to prevent elements from changing states while
events are being processed. However events are going to be processed
nonetheless in those elements if sent directly via pads, so protection must
already be implemented inside the elements for event handling if it is needed.

As such having the lock here is not very useful and is actually causing
various deadlocks in different situations as described in

2d427c75ae bin: Post a LATENCY message with async-handling=TRUE if the PLAYING state is reached
Otherwise each bin might have a different latency in the end, causing

The bin will still first handle latency internally as before, but gives the
overall pipeline the opportunity to update the latency of the whole pipeline
afterwards.

446b3e6ddc plugin: Don't do lossy shift on hash
In plugin is responsible for calculating a hash of the dependencies
in order to determine if the cache should be invalidated or not.
Currently, the hash combining method removes a bit of the original
have before combining with an addition. As we use 32bits for our hash
and shift 1 bit for each file and directory, that resulting hash only
account for the last 32 files. And is more affected by the last file.

Rotating technique (shifting, and adding back the ending bit), can be
use to make the addition non-commutative. In a way that different order
gives different hashes. In this case, I don't preserve this behaviour
because the order in which the files are provided by the OS is
irrelevant.

In most cases, the XOR operation is used to combine hashes. In this
code we use the addition. I decided to preserve the addition because
we make use of non-random hash ((guint) -1) in the algorithm for
matching files that are not really part of the hash (symlinks, special
files). Doing successive XOR on this value, will simply switch from
full ones, to full zero. The XOR used with whitelist has been preserved
as it's based on a fairly randomized hash (g_str_hash).

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]).
