Joe Finney 2547adaa9c BUGFIX: Updated security requirements for notify/indicate descriptors to match the associated characteristic
Required to both ensure security is not circumvented, and also to initiate bonding via a notification request.

Andres Amaya Garcia 4b3a1c85b5 Allow GattAttributes to have fixed length
Previously the concepts of initLength and lenth were clearly separated.
However, this was at the cost of registering all characteristics in the
SoftDevice as having variable length. Clearly, this is not the desired
behaviour. Therefore, an additional field '_hasVariableLen' is added to the
GattAttribute to address the problem. Also, the GattAttribute and
GattCharacteristic constructors have been modified to take a boolean that
sets '_hasVariableLen'.

**NOTE:** Changes to this module will cause projects to fail the build stage
if changes to the BLE_API are not published first.

Andres Amaya Garcia 3fb32e167f Separate concept of minlen and len for BLE chars
In previous versions of BLE_API the GattCharacteristic initLen parameter is
named minLen as well. When the characteristic is committed to the SoftDevice
the value of initial length is also used as the minimum length of the
characteristic value. Furthermore, the test (max_length == min_length) is used
to determine whether the characteristic value has variable length. This is
slightly confusing and also causes problems if the user wishes to use a
characteristic with variable length but the initial lenght is equal to max

To solve this problem the characteristic is now always committed to the
SoftDevice as variable. Furthermore, the API only maintains the current lenght
and the max length i.e. the field initialLen in the GattAttribute is removed.
In nRF5xGattServer all calls to getInitialLength() are removed and replaced
with getLength().

* This change requires updates to ble.
* Ideally we would like the characteristics to be declared as 'variable' only
when necessary, but this requires changing the signature of the
GattCharacteristic and GattAttribute constructors. Therefore, it will be part
of a separate pull request.

Andres Amaya Garcia 97a65815ed Introduced changes for memory savings
Moved GattSecurityManager and GattClient to be allocated dynamically and
reduced the size of some arrays to increase memory savings.
