Joe Finney 18236810a3 microbit: BLE Profile Beta 1
First functionally complete BLE profile, matching BLE speicfication v1.6.
More specifically, the following services are now functional:

  - AccelerometerService
  - MeganetometerService
  - EventService
  - TemperatureServide
  - IOPinService
  - DFUService
  - ButtonService
  - LEDService

Also, updates to underlying device drivers to enable greater configurability:

  - MicroBitCompass now supports variable sample rates and temperature sensing
  - MicroBitAccelerometer now supports variable sample rates and ranges
  - MicroBitThermometer introduced
  - MicroBitMessageBus adapted to permit enumeration and block removal of listeners

Finally, MicroBit DFU Service has been changed to the new UUIDs specificed in v1.6 of BLE spec.

Damien George 0dcb6834ec microbit: Use default constructor for MatrixPoint so data is ROMable.
Previous to this patch an explicit constructor was provided for creating
MatrixPoint instances, which meant that such objects could not be put in
ROM (since they needed to be constructed at runtime).

By using the defualt construction method for structs the MatrixPoint map
is now compiled into the rodata section, hence freeing up RAM.

Saves: 4 bytes data, 56 bytes bss, 148 bytes code.

Joe Finney 3cfc7ec6e7 microbit: Ammendments to ensure fiber is never pages out due to eventing and minor cleanups
- renamed fiber flag to be more general.
- renamed idle to idleFiber to be consistent with the rest of the code.
- factored content of idle() into a funciton to avoid dupication.
- added test case to MessageBus::process() to avoid forking fibers if not requested.
- removed fiber_allow_run_idle_within mutator in favour of exposing currentFiber, as a more general solution.

Damien George 9ccdd25e9f microbit: Allow to run the idle task within the current fiber's stack.
If there is only 1 main fiber (plus the idle fiber) then enabling this
new feature for the main fiber (using fiber_allow_run_idle_within())
will mean that no heap is needed to swap the stack out.

Joe Finney 2c9f63902c microbit: Message Bus updates to support URGENT events queue optimisations
Added new URGENT listener type, that ensures immediate, non queuing delivery of events.
Introduced two-pass algorithm into message bus. Only events with an event listener are now
queued at ingress - this reduces unecessary memory usage for 'uninteresting' events.

Joe Finney a61bd49620 microbit: BUGFIX: Memory leak in ManagedType.h
Corrected corner case memory leak. Instances of ManagedType<> created using the default
constructor would create a reference counter by default, with a value of 0. However, if
destructor or copy-assigned in this state, this reference count would not be destroyed,
resulting in a 4 byte leak on the heap for each occurence.

Joe Finney 3395f66d3d microbit: Added configurable event processing options into MicroBitEvent
Events in the micro:bit runtime are normally launched through making an instance
of the MicroBitEvent class. This update added configuration support to all the
code creating the MicroBitEvent decide if the newly created event should then be
automatically queued on the MessageBus or processed immediately by event handlers.

Joe Finney a875d5fccd microbit: Added configurable concurrency modes for MicroBitMessageBus handlers.
MessageBus handlers can now have one of four concurrency modes for the eventuality
of an event being raised whilst a previous event is still being processed. An additional
(optional) parameter is provided to the listen() functions to allow this to be selected
on a per event handler basis. The permissable options are:

MESSAGE_BUS_LISTENER_REENTRANT:
The event handler is fired with the new event, regardless of whether or not
a previous event is still be processed by that handler.

MESSAGE_BUS_LISTENER_QUEUE_IF_BUSY:
The new event is queued until such a time as the previous event has completed
execution. The new event is then processed. This option does not preclude the
processing of the new event by other event handlers.

MESSAGE_BUS_LISTENER_DROP_IF_BUSY:
The new event is dropped, and will never be processed the the event handler.
This option does not preclude the processing of the new event by other event handlers.

MESSAGE_BUS_LISTENER_NONBLOCKING:
The event handler is self-declaring that it never blocks. This flag is used purely
for optimisation, as it permits direct execution of the event hadnelr without inducing
any overhead from the scheduler.

In addition, the following minor revisions were made in this release:

* Cleanup of the #include dependencies contained in the microbit-dal .h files
* Bugfix to the scheduler block on event matching code.
* Introduced a MICROBIT_ID_ALERT MessageBus channel, for general purpose eventing using nonces.

Joe Finney 8e1a15c79f microbit: Added support for custom configuration files through yotta
A header file containing custom configuration options for the microbit:runtime can
now be defined through a yotaa configuration option.

For example, including the following inside a top level config.json file
will load configuration options from a file called "MicroBitCustomConfig.h" that is stored
alongside an application's main.cpp. Any options defined there will override the defaults
defined in microbit-dal/inc/MicroBitConfig.h :

{
   "microbit" :{
      "configfile" : "source/MicroBitCustomConfig.h"
   }
}
