condition.

c90fccc256 backend-drm: fix race during system suspend
Depending on system loading, weston-launcher could drop the drm
master access before the compositor and all the clients receive
the notification. In this case, some commit could be sent to the
drm driver too late and get refused with error EACCES.
This error condition is not properly managed and causes weston to
hang.

Change the return type of start_repaint_loop() and repaint_flush()
from void to int, and return 0 on success or -1 if the repaint has
to be cancelled.
In the callers of start_repaint_loop() and repaint_flush() handle
the return value and cancel the repaint when needed.
In backend-drm detect the error EACCES and return -1.
Note: to keep the code cleaner, this change inverts the execution
order between weston_output_schedule_repaint_reset() and
repaint_cancel().

No need to wait for suspend or for any notification; in case the
weston reschedules a repaint, it will get EACCES again.
At resume, damage-all guarantees a complete repaint.

This fix is for atomic modeset only.
Legacy modeset suffers from similar problems, but it is not fixed
by this change. Since drm_pending_state_apply() never returns
error for legacy modeset, this change has no impact on legacy
modeset.

f74c35b1f4 libweston: Notify client for change in content-protection status
The change in an output's content-protection may trigger a change in
the surface's content-protection status, and inturn the
content-protection available for the client.

This patch recomputes the content-protection level for a surface,
in case there is a change in content-protection level of an output,
showing the surface. In case of a change in the surface's
content-protection, the client associated with that surface is
notified.

4b6e73d617 libweston: Add support to set content-protection for a weston_surface
The protection requested for a given surface, must reach through the
weston_surface::pending_state, in the commit-cycle for the
weston_surface, so that it gets updated in the next commit.

As some protection is requested for a given weston_surface, it means
protection must be set for each of the outputs which show the surface.

While setting the protection of a weston_output, care must be taken
so as to avoid, degrading the protection of another surfaces, enjoying
the protection. For this purpose, all the weston_surfaces that are
shown on a weston_output are checked for their desired protection.
The highest of all such desired protections must be set for the
weston_output to avoid degrading of existing protected surfaces.
A surface requesting protection for a lower content-type can still be
provided protection for a higher type but the converse cannot be
allowed.

This patch adds support to set content-protection for a suface, which
inturn sets the content-protection for each of the outputs on which
it is shown, provided, none of the existing surface's protection
request is downgraded.

4f64ff8b2f libweston: Compute current protection for weston_output and weston_head
The actual protection status for a given weston_head depends upon the
corresponding drm_head's connector HDCP properties. On the other hand,
the actual protection for a weston_output is the minimum of the
protection status of its attached heads.
As a head's protection changes, the current protection of the output
to which the head is attached is recomputed.

This patch adds the support to keep track of the current
content-protection for heads and the outputs.

2690a77088 libweston: Add support to set content-protection for a weston_output
For making an output secure, the content-protection should be set for
each of head attached to that output. So whenever the protection for
a weston_output is desired, it means that protection is desired for
each of the weston_head attached to that weston_output.

This patch introduces a new enum in libweston to represent the
requested/current protection statuses, equivalent to the type enum
defined by the weston-secure-output protocol. The new enum helps to
extend the content-protection status and requests to libweston and
the backends.
This patch also adds a new member desired_protection to store the
desired protection for an output in weston_output.

78984ee971 libweston: Define head, output and compositor group
Also, add tag symbols related to 'weston_head'.

The bridge between sphinx and doxygen (breathe) has a useful directive:
doxygengroup. By using it we can scoop out symbols we'd like to display
documentation from/of.

At the same time some bits of the code has been using '\memberof' (a
doxygen command useful in C code to establish class like
relationship between objects and functions) but this seems not to be
recognized by the sphinx bridge.

Until we find a better solution, we replace '\memberof' command with
'\ingroup' one as to tag the symbols with an "object". This patch does
that for 'weston_head' object.

b0e16d4c53 backend-rdp: allow to force compression off
By default the client communicates its preference with regards to
compression to the server. However, some clients always use
compression, which is not ideal for certain environments (e.g.
low performance embedded devices in a local network with plenty
of bandwidth). Allow to disable compression server-side which will
override the clients request for compression.

8d23ab78bd backend-drm: handle multiple drm nodes with logind
When using logind launcher, we receive a PauseDevice "gone" message
from logind session management for each device we close while looking
for KMS devices.

Make logind notify the backend of the device add/remove so that the
backend can decide what to do, instead of assuming that if it is a
DRM_MAJOR device the session should be (de)activated. The backend can
then react to its specific device.

Fixes #251

3d5d9476e3 Rename compositor.h to libweston/libweston.h
The main idea is to make libweston users use the form

 #include <libweston/libweston.h>

instead of the plain

 #include <compositor.h>

same form as an external project using libweston would.
