Fixes a configure error with gst-build:
subprojects/gst-plugins-base/meson.build:235:2: ERROR: Fetched variable 'gst_check_dep' in the subproject 'gstreamer' is not a dependency object.
The avg_bitrate is an unsigned int, so the gst_util_uin64_scale() function can't
be used for it, as it expects signed integers for the fraction parts arguments.

Make our own deprecation marker for libgstcheck,
since the function declaration must contain the
right API export decorator (GST_CHECK_API) and
not the one for GStreamer core.
Don't return a value from a function that doesn't
return a value using the returned value from a
function that also doesn't return a value.
gstbitwriter.h(265): warning C4098: 'gst_bit_writer_align_bytes_unchecked': 'void' function returning a value
Instead, use -fvisibility=hidden and explicit exports via GST_EXPORT.
This should result in consistent behaviour for the autotools and
Meson builds where this is done already, and will allow us to drop
the win32 .def files.
And make use of it in the typefind element. It's useful to distinguish
between the different errors why typefinding can fail, and especially to
not consider GST_FLOW_FLUSHING as an actual error.

And make use of that in the typefind element to also be able to make use
of the extension in push mode. It previously only did that in pull mode
and this potentially speeds up typefinding and might also prevent false
positives.

gst_base_transform_transform_caps can return NULL in various conditions
thus we should not treat its result as valid caps.
In all other places NULL is properly handled.
The processing deadline is the acceptable amount of time to process the media
in a live pipeline before it reaches the sink. This is on top of the algorithmic
latency that is normally reported by the latency query. This should make
pipelines such as "v4lsrc ! xvimagesink" not claim that all frames are late
in the QoS events. Ideally, this should replace max_lateness for most applications.

We need all relevant events of a segment to have consistent seqnum:
* GST_EVENT_SEGMENT
* GST_EVENT_EOS
If we are push-based and create a new segment, use the same seqnum
as the upstream event.
If we are pull-based, use the seqnum of that newly created segment
event everywhere
strncpy() is assumed to be for strings so the compiler assumes that
it will need an extra byte for the string-terminaning NULL.
For cases where we know it's actually "binary" data, just copy it
with memcpy.

GstBitWriter provides a bit writer that can write any number of
bits into a memory buffer. It provides functions for writing any
number of bits into 8, 16, 32 and 64 bit variables.

Meson supports building both static and shared libraries in a single
library() call. It has the advantage of reusing the same .o objects and
thus avoid double compilation.

And make the drop() functions expect a 0-based index too,
this addresses a longstanding FIXME. This will not break
backward compatibility, because the drop() functions
were previously only meant to be used with the index
returned by find().
