Add a READONLY property flag to makr properties READONLY
Set the base_volume and volume_step in the acp device
Send the base volume and step as REAONLY properties. Use these
in pulse layer.
Add HARDWARE flag to mark a property that does some hardware control.
Mark the device volume/mute property as HARDWARE or not.
Use the HARDWARE property in pulse to set the right flags.
Always take the state of the builder to get the newly filtered
object, even in the case there is no filter.
Handle the case where we can't copy the pod in the case of
a NULL filter by reverting the state of the builder.
Rework the function a bit to make it possible to pass a NULL
result (to calculate the required size, for example)
Fixes#226
The choice array might have excess elements when the type has been
changed, for example by fixation. This is not a problem and the
excess elements should simply be ignored.
If an ID cannot be de-referenced, e.g., because the builder buffer is
too small, spa_pod_filter() still reports success, but the result is
NULL. Any subsequent access to result will cause a segfault.
Return an error if no pod is found to properly propagate and handle the
error.
The segfault can be reproduced by using the v4l2 module with Vivid
devices [0], because the buffer for the v4l2 controls is too small.

spa_pod_builder_frame() should return the position in the builder
memory or NULL when the frame doesn't fit. Check the size of the
frame instead of assuming the frame is already written to the
buffer.
Remove the done and error callbacks. The error callback is in an
error message. The done callback is replace with spa_pending.
Make enum_params take a callback and data for the results. This allows
us to push the results one after another to the app and avoids ownership
issues of the passed data. We can then extend this to handle the async
case by doing a _wait call with a spa_pending+callback+data that will
be called when the _enum_params returns and async result.
Add a sync method.
All methods can now return SPA_RESULT_IS_ASYNC return values and you
can use spa_node_wait() to register a callback when they complete
with optional extra parameters. This makes it easier to sync and
handle the reply.
Make helper methods to simulate the sync enum_params behaviour for
sync nodes.
Let the transport generate the sequence number for pw_resource_sync()
and pw_proxy_sync(). That way we don't need to keep track of numbers
ourselves and we can match the reply to the request easily.
Remove the spa_pod_iter helpers
Remove builder/parser vararg recurse option, you have to
manually recurse into structures when needed. This simplifies
things a lot.
Pass spa_pod_frames to builder and parser explicitly, we don't
have to keep an internal stack anymore.
The parser is now almost a mirror image of the builder.
Make the parser safer when iterating over objects, add functions
to check and get pod contents in a safe way.
Make the builder return errno style results on errors
Improve performance of object properties when they are stored and
retrieved in the same order.
Add many more tests for the builder and parser
Add some benchmarks
Automatically parse and build key/value when in objects without having
to prefix the key with ":"
Automatically build control/value when in sequence without the "."
prefix.
Remove the builder with key/pod, taking a reference to the stack built
temporary pods is not allowed in c++. We can use the varargs version
with the same convenient syntax.
Remove the parser "*" option, it is unused.
Improve spa_pod_builder_add_* and spa_pod_parser_get_* and make them
look similar.
