* LinkManager::createConnectedLink: use make_shared to avoid separate allocation
Also avoids some memory leaks when returning early.
* fix LinkManager: set setAutoConnect()
* fix MAVLinkProtocol: use a weak_ptr to check if the link stays valid
It is not enough to check if the link is valid only on entering the method.
If message handling called VehicleLinkManager::closeVehicle(), the link
was removed, and possibly deleted. If more mavlink messages were in the
same buffer, the link was accessed again, triggering a segfault.
This happened for example when rebooting the vehicle from parameter editor.

* FTPManager: fix uninitialized Request
- Parts of the header were uninit
- zero init the payload allows for mavlink trimming
* Fix ~TerrainTile: use delete[] for arrays
* FactGroup: fix expensive & unnecessary object creation and map lookups
Every mavlink message reception was leading to creation of a list and
key lookup for each of the keys. This can easily be avoided and results
in noticeable reduction of CPU load (I'm seeing overall around 4% with
a pixhawk on USB).
The same pattern exists elsewhere as well
* Allow use of AutoConnect and HighLatency options for most link types.
* Remove isAutoConnectAllowed and isHighLatencyAllowed methods and assocated Q_PROPERTYs from LinkConfiguration class. Allow user to configure these properties on all link types.
This mechanism automatically queues data into the correct thread where necessary, otherwise the method is invoked directly with low overhead.
At the same time remove the UDP socket event workaround. It is not a problem.

- Lots of additional changes along with this:
- More exposure of objects/properties to Qml
- Much restructuring in LinkManager and LinkManager clients

This is needed for Android since it needs to communicate with java apis
which require everything on the main thread. The additional thread was
not really needed since you can implement using a signal based approach
which ends up being the same thing.
Link ids were being used interchangeably with the mavlink channel for
the link. Link ids handed out as a numerically increasing integer. Once
the counter went past MAVLINK_COMM_NUM_BUFFERS all hell would break
loose and cause memory corruption.
The goal of this first installment is to organize the code a bit so it's more readable,
clean up a bit of left over cruft, and manage link configurations (and links in general).
There's also a partial fix for the databits and stopbits. I'm unsure how to deal with the logic
around the 'is_cdc' variable, as I can't really follow what it's for.
Plus a large number of other changes to allow for orderly shutdown of
objects without crashes or asserts. This is need for unit tests to
create/delete global state around every test.
Centralize all connecting and disconnecting of links through
LinkManager::[Connect|Disconnect]Link api. Connect/Disconnect no longer
allowed through LinkInterface. This allows creation of new
LinkManager::setConnections[Suspended|Allowed] methods to disallow
connections as needed.
This api doesn’t make any sense given the fact that LinkInterface
signals bytesReceived with the bytes in the signal. Also the reason why
it is never called!
