a78a9cf0c3 basesrc: Add new API for handling GstSegment update by subclass
Add API gst_base_src_new_segment() for subclass to be able to
signalling new GstSegment which should be applied to following
buffers.

89dfda56e3 base: GstBaseSrc/GstBaseSink::get_caps: add (nullable) to filter
The virtual method named `get_caps` in both `GstBaseSrc` and
`GstBaseSink` has a `filter` parameter which can be `NULL` (the
default implementation in GstBaseSrc already considers the case).
Before this commit, there was no gtk-doc annotation representing this
fact, which caused the corresponding entry in the GIR file to also
miss this fact.

This caused bugs in other places, such inducing the Vala compiler to
introduce a wrongly assert on `(filter != NULL)` in every
implementation of the `get_caps` method implemented in Vala.

09141c6e1f Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

* Making sure that `static inline` function are in the GIR (by first
  defining them, and make sure to mark as skiped)
* Do not try to link to unexisting symbols

7e2ace8618 base: GST_EXPORT -> GST_BASE_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).

65cfafb3b9 basesrc: getters for pool and allocator
Sometimes the sources would use the buffer pool or the memory allocator for
something else than just allocating output buffers; for example, querying for
different parameters, such as a bigger number of buffers to allocate by the
pool.

This patch expose a two getters accessors: one for the buffer pool and the
other for the memory allocator.

43abf99a8a caps: avoid using in-place oprations
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.

Add a method to enable async start behaviour. The subclass can then complete the

The base class can wait for the start to complete with
gst_base_src_start_wait().

c35e0de65e basesrc: add fill vmethod to basesrc
Add a new fill virtual method to basesrc. The purpose of this method is to fill
a provided buffer with data.
Add a default implementation of the create method that allocates a buffer and
calls the fill method on it. This would allow the base class to implement
bufferpool and allocator negotiation on behalf of the subclasses.
Fix the blocksize property.
Make filesrc use the new fill method.

f8168cd75f basesrc: add dynamic size handling
This allows subclass to indicate that size reported by src may not be static
and should as such be updated regularly, rather than only when really
needed.

Particular examples are filesrc or fdsrc reading from a file that is still
growing (e.g. being downloaded).

Fixes #652037.

3d2127f865 Revert "query: allow _make_writable on query handlers"
This reverts commit cf4fbc005c.

This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.

fae502056f basesrc: Make locking of the segment a bit more strict and update documentation
Updating the segment values must only be done while holding the
STREAM_LOCK and OBJECT_LOCK. This means, reading can be done as
long as one of them is held, not both, which removes some lock-unlock
blocks from performance critical code paths.

Also document, that gst_base_src_set_format() *must* be called in
states <= READY and add an assertion for this. Changing the format
later will completely mess up the segment information.
