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

length.



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().



*NOTES:*

* 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.
