nested: Ensure that the nested Platform object stays alive for at least as long as the nested Display object needs it (LP: #1372276). Fixes: https://bugs.launchpad.net/bugs/1372276.

Avoid polling in a loop with timeout zero most of the time. That
will only waste CPU. (LP: #1373809)

This also fixes test failure LP: #1373826. Fixes: https://bugs.launchpad.net/bugs/1373809, https://bugs.launchpad.net/bugs/1373826.

frontend: platform: provide a way for the frontend to perform platform specific actions upon receipt of buffer from the client. Split out the 3 platform ipc operations into its own interface.

I renamed: BufferIPCPacker -> BufferIpcMessage. (packing is what it does, a message is what it is)

I made note that drm_auth_magic() should also be a function in the PlatformIpcOperations interface, this would remove the mg::Platform from the frontend altogether.

Reduced visible input lag by approx one frame (on 59-60Hz displays)*

It's not enough to resample input down to a rate similar to the refresh
rate. That only reduces your lag from "always growing" to a constant one
frame.

This proposal reduces lag further to almost zero, by periodically (five
times per second) bringing the cooked event interval in-phase with the
refresh rate. Thus about every 12th frame, the client is able to respond
to an input event and get composited with one frame less buffer lag than
before.

* Displays >>60Hz will already be experiencing this trick and won't
  benefit further.

Fix jerky/stuttering event delivery that could happen inside
nested servers sometimes (LP: #1372300)

Waiting significantly longer than a frame before consuming previously
batched events is too dangerous in slow raw-event environments
(nested servers or very slow input devices). It causes frame skipping.
