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.

This protocol allows a client to ask the compositor to only allow it to
be displayed on a "secure" output. This initial version of the protocol
supports HDCP.
This is loosely based on the chromium secure-output protocol [1].
This protocol is mostly useful for closed system, where the client can
trust the compositor, such as set-top boxes. This is not a way to
implement any kind of Digital Rights Management on desktops. The
compositor would be free to lie to the client, anyway.

weston_desktop_surface_unlink_view() does now call weston_view_destroy() so the
weston_view is not destroyed here. This is a problem because the view remains in
the weston_layer view_list. If ivi_view_destroy() is called from
ivi_layout_surface_destroy() and the view list is rebuilt in the 'removed'
signal, then the list gets corrupted when the view is destroyed immediately
afterwards.
Fix this by calling weston_view_destroy() unconditionally for all view.

Unfortunate left over which was not removed once we had the script in
place to regenerate the documentation. A side-effect was the fact that
we still ran the script even if 'docs' target was called, effectively
nullifying the fact that 'docs' target was ran at all. For instance,
'install' would've been executing the script even if 'docs' target
was called before.
This removes the doxygen_target entirely and the depends of sphinx
target on it, makes building and installing docs a bit faster.

Pads launchers with the empty space that used to be around them. Moving
pointer to 0,0 and clicking launches the preferred app. First launcher
has more padding at its start to look nice.
Moves the clock to the right edge with same padding. Keeps one of the
two values for text extents that the code was already retrieving but
never read. Horizontal panel position centers the clock.
Sets text in the panel, meaning tooltips and the clock, to consistent 14
units of the default system font at 85% of the max brightness, so it's
less tiring on eyes.
partial_update is an EGL extension which allows us to inform the driver
ahead of time the limits of the areas we'll be writing to. This helps
performance for GPU hardware which renders into a local tile buffer:
informing the driver of the rendering extents means it can avoid
fetching unchanged tiles into the tile buffer and subsequently writing
them out.
The extension complements rather than replaces EGL_EXT_buffer_age (used
before partial_update to know which areas we need to update) and
EGL_KHR_swap_buffers_with_damage (used after partial_update to inform
the winsys of the changed region).
Note however that partial_update deals in buffer-damage regions ('what
has changed since the last time I used _this_ buffer?'), whereas
swap_buffers_with_damage deals in surface-damage regions ('what has
changed since the last time I rendered?'). An explanatory diagram can be
found in the specification:

The buffer_damage variable stores accumulated damage from previous
frames. This is the area that, before considering our current repaint
request, we need to repaint in order to bring the older buffer up to

Technically it is storing which areas of the border are damaged.
However, we already have damage-region variables which need to be
translated by the border region. Rename the variable to not contain the
word 'damage' to reduce confusion.

eglSwapBuffersWithDamage has to convert a damage region from Weston's
global co-ordinate space, into the co-ordinate space for EGL rendering
into a buffer for that output.
The conversion from the global co-ordinate space in logical pixels to
the output space in buffer pixels is slightly long and error-prone,
involving translating by the output's offset within the global
co-ordinate space, multiplying by output scale, and also translating to
allow for any borders we paint around the output.
After this is done, we need to flip the co-ordinates in the Y axis to
account for the lower-left-origin co-ordinate space used by EGL.
Since we want to reuse this for partial_update, but using a different
source region, extract this conversion into a well-commented helper we
can reuse.

Fan debug mode repaints the whole surface in order to clear any 'trails'
left over from previous fan paints. If this happens, fall back to using
regular eglSwapBuffers rather than eglSwapBuffersWithDamageEXT, since
the damage region we would pass will be too small.

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.

This is adds basic configuration files for doxygen and for breathe,
which is a doxygen-to-sphinx bridge that can document C symbols.
Breathe is configured with default project 'weston' and implicitly adds
:members: and :undoc-members: to breathe configuration options.
This allows a shorter way to call breathe directives without the need
specify the project and also to display implicitly all the members,
documented or not.
A 'docs' run_target to force the docs to be re-built has been added.
Initially (the first time the build system is ran) the documentation
will automatically be built, but later re-builds will require the use of
the 'docs' target. This avoid further delays in building weston but in
the same time allows the possiblity to update/improve the documentation
bits to those who want that.

As of the previous commit, we never create state which uses overlay
planes on non-atomic drivers. We can thus remove the calls to
drmModeSetPlane.

drmModeSetPlane and needed to make sure we waited until it was active.
We can thus also remove all the vblank event machinery.

Without atomic modesetting, we have no way to know whether or not our
desired configuration is usable. It might fail for a number of reasons:
scaling limits, bandwidth limits, global resource (e.g. decompression)
unit contention, or really just anything.
Not only this, but there is no good way to ensure that our configuration
actually lands together in the same refresh cycle - hence the 'atomic'
in atomic modesetting. Some drivers implement a synchronously blocking
drmModeSetPlane, whereas others return immediately. Using overlay planes
can thus decimate your framerate.
The pre-atomic API is not extensible either, so we need numerous out
clauses: fail if we're cropping or scaling (sometimes), or changing
formats, or fencing, or ...
Now we've had atomic support stable for a couple of releases, just
remove support for doing anything more fancy than displaying our
composited output and a cursor with drivers which don't support atomic
modesetting.
Support for using overlay planes was already disabled by default when
using the legacy API, and required a debug key combination to toggle it
on by flipping the sprites_are_broken variable. We can ensure that we
never try to use it on legacy by simply ignoring the hotkey when in
legacy mode.
