Armin Krezović a01ab6d525 libweston: Add more functionality for handling weston_output objects
This patch implements additional functionality that will be used
for configuring, enabling and disabling weston's outputs. Its
indended use is by the compositors or user programs that want to
be able to configure, enable or disable an output at any time. An
output can only be configured while it's disabled.

The compositor and backend specific functionality is required
for these functions to be useful, and those will come later in
this series.

All the new functions have been documented, so I'll avoid
describing them here.

v2:

 - Minor documentation improvements.
 - Rename output-initialized to output->enabled.
 - Split weston_output_disable() further into
   weston_compositor_remove_output().
 - Rename weston_output_deinit() to weston_output_enable_undo().

 - Make weston_output_disable() call two functions mentioned
   above instead of calling weston_output_disable() directly.
   This means that backend needs to take care of doing backend
   specific disable in backend specific destroy function.

v3:

 - Require output->name to be set before calling
   weston_output_init_pending().
 - Require output->destroying to be set before
   calling weston_compositor_remove_output().
 - Split weston_output_init_pending() into
   weston_compositor_add_pending_output() so pending outputs
   can be announced separately.
 - Require output->disable() to be set in order for
   weston_output_disable() to be usable.
 - Fix output removing regression that happened when
   weston_output_disable() was split.
 - Minor documentation fix.

v4:

 - Bump libweston version to 2 as this patch breaks the ABI.

*

* add it to the list view->geometry.transformation_list. Whenever you
* change the list, anything under view->geometry, or anything in the
* weston_transforms linked into the list, you must call
* weston_view_geometry_dirty().
*
* The order in the list defines the order of transformations. Let the list
* contain the transformation matrices M1, ..., Mn as head to tail. The
* transformation is applied to view-local coordinate vector p as
* P = Mn * ... * M2 * M1 * p
* to produce the global coordinate vector P. The total transform
* Mn * ... * M2 * M1
* is cached in view->transform.matrix, and the inverse of it in
* view->transform.inverse.
*
* The list always contains view->transform.position transformation, which
* is the translation by view->geometry.x and y.
*
* If you want to apply a transformation in local coordinates, add your
* weston_transform to the head of the list. If you want to apply a
* transformation in global coordinates, add it to the tail of the list.
*
* If view->geometry.parent is set, the total transformation of this
* view will be the parent's total transformation and this transformation
* combined:
* Mparent * Mn * ... * M2 * M1
