ed5d888ba5 gstsample: new API
gst_sample_set_buffer
gst_sample_set_caps
gst_sample_set_segment
gst_sample_set_info
gst_sample_is_writable
gst_sample_make_writable

This commit makes it possible to reuse a sample object and avoid
unnecessary memory allocations, for example in appsink.

In addition, writability is now required to set the buffer list.

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.

18fe36a286 basesrc: add buffer list support
Add a gst_base_src_submit_buffer_list() function that allows subclasses
to produce a bufferlist containing multiple buffers in the ::create()
function. The buffers in the buffer list will then also be pushed out
in one go as a GstBufferList. This can reduce push overhead
significantly for sources with packetised inputs (such as udpsrc)
in high-throughput scenarios.

The _submit_buffer_list() approach was chosen because it is fairly
straight-forward, backwards-compatible, bindings-friendly (as opposed
to e.g. making the create function return a mini object instead),
and it allows the subclass maximum control: the subclass can decide
dynamically at runtime whether to return a list or a single buffer
(which would be messier if we added a create_list virtual method).

e5c15f6b96 utils: Never return a group_id of 0, add GST_GROUP_ID_INVALID
Various plugins use special values (0 or G_MAXUINT32) as an
invalid/unset group_id, but nothing guarantees a groupid won't have
that value.

Instead define a value which group_id will never have and make
gst_group_id_next() always return a value different from that.

API: GST_GROUP_ID_INVALID

d8e7fc40b1 harness: add gst_harness_take_all_data() + _take_all_data_as_{bytes,buffer}()
Convenience function to just grab all pending data
from the harness, e.g. if we just want to check if
it matches what we expect and we don't care about
the chunking or buffer metadata.

86abf49c23 gst: add a promise object
An object that can be waited on and asked for asynchronous values.
In much the same way as promise/futures in js/java/etc

A callback can be installed for when the promise changes state.

Jan Schmidt <jan@centricular.com>

d106390adc element: add gst_element_foreach_*pad()
Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.

This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.

After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.

This is also a replacement for gst_aggregator_iterate_sink_pads().

7d930b8693 buffer: Add GstReferenceTimestampMeta
This is a meta that generically allows to attach additional reference
timestamps to a buffer, that don't have to relate to the pipeline clock
in any way.

Examples of this could be an NTP timestamp when the media was captured,
a frame counter on the capture side or the (local) UNIX timestamp when
the media was captured.
