text: Fix text-input for multi-seat

Multi-seat configurations currently break the text-backend, crashing
weston.  This is an attempt to clean up any crashes and have somewhat
sensible input panel behavior with multi-seat.

Store a link to the manager that created a text_input, use this to
ensure that only a single panel gets popped up at a time, since there
is only one manager.

Replace deactivate_text_input with deactivate_input_method: multiple
input methods may focus the same text_input, so deactivating a text_input
is weird in multi-seat and confusing to perform.

In destroy_input_method_context set the context's input_method's context
pointer to NULL to prevent a dangling pointer.

compositor: send the output_created signal after inserting it in the list

The compositor's output_created signal used to be sent in weston_output_init()
which the backend call before putting the output in the output_list.
This caused problems when creating a new view in a listener to that signal,
because weston_view_assign_output() doesn't yet know the new output exists.
To fix this add a new weston_composito_add_output() func which adds the
output in the list and later sends the signal, and make the backends call
that.

editor: implement Cut,Copy,Paste

weston-editor is the only stock client spawning the virtual
keyboard ; which means it may be the only client able to
obtain some special characters (depending on the user's
keyboard layout).

If we implement Cut, Copy and Paste, the user has now a way
to copy such characters to other useful clients (such as
weston-terminal). Plus, it demonstrates text data exchange
between two clients of different nature.

Functionality is implemented in a right-click menu and the
Ctrl+Shift+X/C/V bindings, just as in weston-terminal.

tests: ivi_layout test infrastructure

Testing the ivi_layout API requires two things:
- the tests must be written as a controller module to access the API
- the tests need a helper client to create some objects that can then be
  managed via the API

This patch adds all the infrastructure and two different kinds of
example tests.

Internal ivi-shell (ivi_layout) API tests are listed as ivi-*.la files
in TESTS in Makefile.am. Weston-tests-env detects these, and runs Weston
with ivi-shell, and loads the given module as a controller module, not
as a normal plugin.

The test controller module ivi-*.la will launch a helper client. For
ivi-layout-test.la the helper client is ivi-layout.ivi.

The helper client uses the weston-test-runner framework to fork and exec
each TEST with a fresh connection to the compositor.

The actual test is triggered by the weston_test_runner protocol
interface, a new addition to weston-test.xml. The helper client uses
weston_test_runner to trigger a test, and the server side of the
interface is implemented by the test controller module
(ivi-layout-test.la).

The server side of weston_test_runner uses the same trick as
weston-test-runner.h to gather a list of defined tests. A test is
defined with the RUNNER_TEST macro.

If a test defined by RUNNER_TEST succeeds, an event is sent to the
helper client that it can continue (or exit). If a test fails, a fatal
protocol error is sent to the helper client.

Once the helper client has iterated over all of its tests, it signals
the batch success/failure via process exit code. That is cought in the
test controller module, and forwarded as Weston's exit code.

In summary: each ivi_layout test is a combination of a client side
helper/setup and server side actual tests.

compositor-wayland: ignore frame callback's time

Weston running the Wayland backend is nested. The parent compositor uses
an unknown clock for the frame callback timestamps. This is quite likely
a different clock from what the nested Weston chose as its presentation
clock.

This means we cannot reasonably read the presentation clock and assume
it has any relation to the timestamp got from the frame callback. In
fact, this was seen to cause absurd repaint delays, trigger the insanity
check, reduce fraterate, etc. problems, because we assume we can read
the clock and compute the remaining repaint delay.

As we can't use the timestamp, ignore it, and read our own presentation
clock instead.

The X11 backend does not suffer from this, because there the parent
window system never provides us any timestamps, so we always read our
own clock.

compositor: add repaint delay timer

This timer delays the output_repaint towards the end of the refresh
period, reducing the time from repaint to present.

The length of the repaint window can be set in weston.ini.

The call to weston_output_schedule_repaint_reset() is delayed by one
more period.  If we exit the continuous repaint loop (set
output->repaint_scheduled to false) in finish_frame, we may call
start_repaint_loop() unnecessarily.  The problem case was actually
observed with two outputs on the DRM backend at 60 Hz, and 7 ms
repaint-window. During a window move, one output was constantly falling
off the continuous repaint loop and introducing additional one frame
latency, leading to jerky window motion. This code now avoids the
problem.

Changes in v2:

- Rename repaint_delay_timer to repaint_timer and
output_repaint_delay_handler to output_repaint_timer_handler.

- When computing the delay, take the current time into account. The timer
uses a relative timeout, so we have to subtract any time already gone.

Note, that 'gone' may also be negative. DRM has a habit of predicting
the page flip timestamp so it may be still in the future when we get the
completion event.

- Do also a sanity check 'msec > 1000'. In the unlikely case that
something fails to provide a good timestamp, never delay for more than
one second.
