Synchronized with git rev 7e8977d8

Author: Rohit Grover

Release 0.3.8

=============



This is a minor set of enhancements before we yotta-ize BLE_API.



Enhancements

~~~~~~~~~~~~



* Minor rework for class UUID; added a default and copy constructor; and a != operator.



* Added copy constructor and accessors for GapAdvertisingParams.



* GapScanningParams:: remove unnecessary checks for SCAN_TIMEOUT_MAX.



* Add a comment header block to explain why BLEDevice::init() may not be safe

  to call from global static context.



* Introduce GattAttribute::INVALID_HANDLE.



* Replace some deprecated uses of Gap::address_t with Gap::Address_t.



Bugfixes

~~~~~~~~



* None.
