Joe Finney 9218e647e0 microbit: Refactor of periodc timer callbacks
- Factored periodic timer funcitonality out of fiber scheduler and into a new SystemTimer module module.
- Enapsulated "ticks" variable within SystemTimer module, with accessor funciton.
- Added accessor/mutator functions to get and set the tick period.
- Added a class wrapper to permit periodic callbacks to both C and C++
- Updated all references in microbit-dal to use this refactored API.

James Devine e115e5af8d microbit-dal: BUGFIX maintain cccd state when service changed fails
Previously, we would rely on service changed to complete successfully
to signify a successful cccd state restore.

However, android doesn’t register for service_changed notifications,
and as a result sd_ble_gatts_service_changed always returns an error.

This meant that cccds would be erased when the complete flag was not
one, which would have been all the time.

Joe Finney d3922d21e9 microbit: Aligning MicroBitButton and MicroBitMultiButton APIs
Updates to MicroBitButton and MicroBitMultiButton to align the API through
which CLICK events are filtered. Also, updates to the mechanism through which
buttonA and buttonB CLICK/LONG_CLICK events are filtered by
MicroBitMultiButotn to reduce RAM footprint.

No changes to external behaviour of these classes.

James Devine 3019e34dd9 microbit: BLE fixes
This commit addresses a number of outstanding issues:

* whitelisting behaviour, form the nrf51-sdk, where an address and an
irk were added to the whitelist

* bond management bugs, from the nrf51-sdk, where one device would
replace another.

Joe Finney 6900bd8415 microbit: BUGFIX supporting repairing of the same device #2829
Re-pairing the same BLE device under SoftDevice 8.0 Nordic SDK 10 appears to
add a second entry to the bonding table when private resolvable addresses are
used by the central device. This adversely affects whitelisting, as only the
first added matching entry will be succesfully added to the whitelist. i.e. A
central device will no longer be able to connect to a micro:bit after pairing
a second time as the older bond will take prescedence.

Althoguh reported to Nordic, a long term fix is not immediately forthcoming.
This patch applies a workaround, by simply reversing the order of the
whitelist before use. As the list is maintained in the order of insertion,
reversing the list guarantees that the entry added to the whitelist will be
the most recently bonded one for any given peer.

Joe Finney 72d14be1d4 microbit: Added ability to define how long a device will remain in panic

Joe Finney c1ae235ebd microbit: On demand suppression on button click events.
MicroBitMultiButton now provides an indication to MicroBitButton instances when an application is actively utilising that button as part of a button group. This
permits that MicroBitButton to more accurately filter events, and provide a
consistent abstraction.

More specifically, this patch:

 - Extends the MessageBus functionality to indicate when listeners are
   attached to events. This allows components to perform on demand tailoring
   of their behaviour.

 - Extends MicroBitMultiButton to indicate to relevant MicroBitButton
   instances when they are part of a button group.

 - Extends MicroBitButton to perform filtering of button events dynamically
   (rather than statically) when part of a MultiButton group.

 - Code cleanup of static functions that are more cleanly implemented as

Joe Finney 8e3e061bec microbit: BUGFIX Fixed incorrect bond table entry count

with the number of bonds.

Joe Finney 2e6459404b microbit: Added configuration to enable/disable BLE security

Default BLE security settings remain unchanged.

James Devine 23d56edbdd microbit: integrated MicroBitStorage with MicroBitCompass
This commit introduces persistent storage for the compass between

setCalibration now also stores the data in FLASH if it differs from
what it contains.

persistent data available that is non-zero.

(i.e. x, y and z are NOT zero).

This ensures that users can code without interference from persistent

Joe Finney d1d78b9b35 microbit: added MicroBitStorage for Persistent data
Integrated simple 1K block buffer to host small amount of persistent

information, such as:

* BLE bonding information.
* Compass Calibration data.
* Thermometer Calibration data.

The block is resident at 0x0003B400 - 0x0003B800.

James Devine 4cefd55ef5 microbit: updated the dal to use a higher resolution ticker.
Previously the DAL relied upon an implementation of a timer that
was very imprecise and lacked resolution, this commit adds a reference
to a frozen repo with us_ticker.c modifications, so that a higher resolution
timer is utilised.

This fixes #13 (finally), and also fixes lower brightness levels when using
DISPLAY_MODE_BLACK_AND_WHITE to not cause a device lockup.

James Devine 3fa9bb09c2 microbit: fixed an off by 10 bug
Missed a zero in a previous commit, that caused a system lockup due to

minimise another feature that needs fixing in the future, where the
timer does not interrupt in the expected time frame.

a more consistent overall API.

Joe Finney e7132b0d13 microbit: Change to BLE bonding table replacement policy
Previous revisions of microbit-dal would handle the case of a bonding request
when the bond table was full by attempting to purge the bonding table on
demand. This suffered two flaws:

 1) Nordic's device manager does not support the purging of the bonding table
while a connection is active (including a pairing request).

 2) Some devices (e.g. Android 4.4.2 take two entries in the bonding table
when paired), thus making predictions of how 'full' the table is challenging.

This patch employs a simpler replacement policy. The maximum size of the bond
table has been increased to 6 (from 4). However, if the bond table contains 4
or more entries when entering pairing mode it will be purged in advance of any
pairing requetss being initiated.

Joe Finney 9026ca6e98 microbit: Optimisation of BLE mutex.
The BLE stack locks out the CPU for long periods of time when necessary. This
can be alleviated by eans of a flag that release the CPU between radio events.

This can cause issues from applications with tighter timing requirements.
This patch only enables this MUTEX when a BLE connection is active, rather
than automatically at startup. Therefore, application that do not actively use
BLE will not suffer this penalty.
