Don't let permissions of an object influence the child permissions,
this is not so easy to manage and needs some more thought.
The result is now that it's possible to see a reference to a (parent)
id that is not visible, but that's ok.
Define a set of standard factory names and document what they
contain. This makes it possible to change the implementation by
mapping the factory-name to a different shared library.
Make a set-prop command to set a property from the config file
into a pw_properties. Pass this to the pw_core_new() and the
main-loop to tweak some stuff.
Move some warns to errors
Make pw_remote_connect_fd() not automatically close the provided
fd but let the caller take care of that. This allows us to reuse
the fd in pipewiresrc.
Fixes#155
Move the epoll functions to the system functions and make the loop
use those. Use simple mask for events instead of enum.
Add the used system api in pw_loop.
Add System API to spa_support and use it where possible.
Pass the system API used in the realtime loops in spa_support as
well and use this in the realtime paths.
Improve bootstrapping, load only the log and cpu interfaces because
those can/need to be shared between instances. Let the core load
the other interfaces.
Add keys to configure the System and Loop implementations used in
pw_loop.
Make a new API to hide some the implementation of eventfd, timerfd
and signalfd along with clock and read/write/ioctl/close functions.
We would like to have plugins use the abstractions so that we
can switch them to something else when needed.
Pass a factory_name in the object_info of monitor and device.
Restructure the factory name to mean something functionaly. With
the factory to library mapping this then means that the implementation
of certain factories can be configured in the config file.
Remove override for resources, it can't work in general.
Rename method to add_object_listener to add a listener for
events/methods from the remote object.
Rename some methods to _call to call the interface and _notify
to notify the listeners.
Remove unused client event to be notified of resource
implementations.
