0c6f5b3e4c gst: Don't pass miniobjects to GST_DEBUG_OBJECT() and similar macros
The argument must be at least a GObject according to the GstLogFunction
definition, and while the default C log function handles miniobjects
just fine this is crashing bindings and user-supplied log functions that
(rightfully) don't expect anything but GObjects.

32b7108d54 info: Take lock around all prinf on Windows
On Windows, concurrent colored gstreamr debug output and usual
stdout/stderr string will cause broken output on terminal.
Since it's OS specific behavior, that's hard to completely avoid it
but we can protect it at least among our printing interfaces side.

e6bd5b4193 miniobject: free qdata array when the last qdata is removed
In cases with many long-lived buffers that have qdata only very
briefly, the memory overhead of keeping an array of 16 GstQData
structs for each buffer can be significant. We free the array when
the last qdata is removed, like it was done in 1.14.

Fixes #436

94ba1cea88 bin: Fix minor race when adding to a bin
This patch simply add a null check around a case where a child may have
been unparented concurrently to the deep_add_remove operation. This was
found by accident in the form of an "IS_GST_OBJECT" assertion, but had
no other known side effect in that test.

dc7b9cec1e message: fix up enum value for GST_MESSAGE_DEVICE_CHANGED
This was added in 1.16 and accidentally duplicated the value of
the existing GST_MESSAGE_REDIRECT.

As the only known user of this message is GStreamer core itself,
and it is quite an obscure message, it seems best to just fix up
the enum value even if that technically breaks API.

815acd88ee info: Fix deadlock in gst_ring_buffer_logger_log
gst_ring_buffer_logger_log calls several functions while formatting
the message which may in turn log a message while we already hold
the mutex. Do all formatting first before acquiring the mutex to
avoid this and reduce the time we hold the mutex.

53bf06c088 bufferpool: Fix the buffer size reset code
The offset in gst_buffer_resize() is additive. So to move back the
offset to zero, we need to pass the opposite of the current offset. This
was raised through the related unit test failingon 32bit as on 64bit
the alignment padding was enough to hide the issue. The test was
modified to also fail on 64bit. This patch will remove spurious
assertions like:

  assertion 'bufmax >= bufoffs + offset + size' failed

53e879c750 gstpad: Probes that return HANDLED can reset the data info field
Before GST_PAD_PROBE_HANDLED was introduced, we had to handle the case
where some probes would reset the probe info data field to NULL. This would
be considered an invalid use-case.

But with GST_PAD_PROBE_HANDLED it is totally fine to reset that, since
the probe has "handled" it.

2fa15d5371 event: add new seek parameter, "trickmode-interval"
When performing a key unit trickmode seek, it may be useful to
specify a minimum interval between the output frames, either
in very high rate cases, or as a protection against streams
that may contain an overly large amount of key frames.

One use case is ONVIF Section 6.5.3:

f62ee97592 buffer: store sequence number for metas
For metas where order might be significant if multiple metas are
attached to the same buffer, so store a sequence number with the
meta when adding it to the buffer. This allows users of the meta
to make sure metas are processed in the right order.

We need a 64-bit integer for the sequence number here in the API,
a 32-bit one might overflow too easily with high packet/buffer
rates. We could do it rtp-seqnum style of course, but that's a
bit of a pain.

We could also make it so that gst_buffer_add_meta() just keeps metas in
order or rely on the order we add the metas in, but that seems too
fragile overall, when buffers (incl. metas) get merged or split.

Also add a compare function for easier sorting.

We store the seqnum in the MetaItem struct here and not in the
GstMeta struct since there's no padding in the GstMeta struct.
We could add a private struct to GstMeta before the start of
GstMeta, but that's what MetaItem effectively is implementation-
wise. We can still change this later if we want, since it's all
private.

97aa82387f device-provider: Allow notifying application of device changes
Thi introduces new APIs to post a `DEVICE_CHANGED` message on the

that can be changed at any time. Atomically changing the device
object notifying that way allow us to abtract away the internal threads.

  - gst_message_parse_device_changed
  - gst_device_provider_device_changed

c164b88ac1 meson: Extract flex version using a regex inside a script
Different builds of Flex on different platforms output different strings
in --version. For example:

macOS:
flex 2.5.35 Apple(flex-31)

Windows:
win_flex.exe 2.6.4
C:\Program Files (x86)\GnuWin32\bin\flex.EXE version 2.5.4

We need to look for a string that looks like a version, which means
a regex till https://github.com/mesonbuild/meson/issues/1609 is fixed.

5688773b91 taglist: Remove (scope call) annotation from gst_tag_register()
This was added in 7fdb15d6a2 but it is wrong. (scope call) is for

There's no appropriate scope annotation for that so we have to skip
