vulkan: add VK_PRESENT_MODE_MAILBOX_KHR support to MirPresentationChain.

client: add different mode selection to MirPresentationChains. Better prepares for supporting more than one vulkan submission mode. (we currently support the required mode, fifo).

Add a regression test for client::BufferStream switching vsync methods
when it finally knows which one to use.

Just a regression test that should have been written earlier.

The reason why the switch must occur is documented in buffer_stream.cpp
The reason why it happens lazily on demand is to distinguish between
swap_buffers and swap_buffers_sync -- only the latter of which has so
far been converted to client-side vsync.
.

Delete unused declaration of SessionMediator::advance_buffer(). Fixes: https://bugs.launchpad.net/bugs/1556205.

Approved by Andreas Pokorny, mir-ci-bot.

4072. By Daniel van Vugt on 2017-03-07

Improve concurrency of the IPC and compositor threads.

The compositor thread is presently blocked waiting for the IPC thread to
complete socket IO, which is bad. This reorders operations to avoid
that delay so the compositor thread is not hostage to IPC performance.

This is the first step on the road to fixing GPU saturation issues
(LP: #1211700, LP: #1665802) but is not yet a fix in itself. Fixes: https://bugs.launchpad.net/bugs/1211700, https://bugs.launchpad.net/bugs/1665802.

Deprecate unused event types: mir_event_type_key & mir_event_type_motion.

Approved by Daniel van Vugt, Andreas Pokorny, mir-ci-bot.

4069. By Daniel van Vugt on 2017-03-07

Reintroduce manual compositor->stop()/start() calls that were removed
in r3996. Turns out we still need them to avoid mode changes initiated by
the server conflicting with redraws, which may crash (LP: #1669752). Fixes: https://bugs.launchpad.net/bugs/1669752.
