Add a list of possible encoders to the connector configuration and
helpers to attach and detach them.
Now that the default configuration has its connector and encoder
correctly, configure the output following the configuration.

Add a list of connectors to vkms_config and helper functions to add and
remove as many connectors as wanted.
For backwards compatibility, add one enabled connector to the default
configuration.
A future patch will allow to attach connectors and encoders, but for the
moment there are no changes in the way the output is configured.

Add a list of possible CRTCs to the plane configuration and helpers to
attach, detach and get the primary and cursor planes attached to a CRTC.
Now that the default configuration has its planes and CRTC correctly
attached, configure the output following the configuration.

Add a list of planes to vkms_config and create as many planes as
configured during output initialization.
For backwards compatibility, add one primary plane and, if configured,
one cursor plane and NUM_OVERLAY_PLANES planes to the default
configuration.

As the configuration will be used by userspace, add a validator to avoid
creating a broken DRM device.
For the moment, the function always returns true, but rules will be
added in future patches.

Creating a new vkms_config structure will be more complex once we
start adding more options.
Extract the vkms_config structure to its own header and source files
and add functions to create and delete a vkms_config and to initialize
debugfs.
Refactor, no functional changes.
