Major changes:
- Dependency to FileHandle removed from base classes
- AT_CellularDevice owns the default FileHandle and shares it with AT -classes
- Hang-up -detection moved as CellularContext::configure_hup(). Cannot be configured via CellularDevice any more.
Result on NRF52840_DK + BG96:

RAM increase is because now ATHandler is no longer created with new -operator but is now member of AT_CellularDevice,
so image tool is able to count it. Actually total RAM consumption has decreased due to removed variables.
Add a missing license header.
Remove semaphores and add +CRTDCP to support async operation.
Fix delete context and disconnect to execute just once.
Add support for NONIP PPD type.
Change CellularNetwork::clear() to virtual so it can be overridden.
- Earlier some variables were public even though used only internally
- Also refactored variables to the end of class definitions
- Removed duplicate _property_array from CellularDevice
- Changed _impl methods as protected
Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
MBED_DEPRECATE macros is added to string-based APIs.
New, non-string-based APIs are added in their place.
Wiced binaries rebuilt
Any existing stubs or mocks are adjusted to compile and run with the newly added non-string based functions.
AT_CellularContext::do_connect() is a virtual API and therefore can be overwritten in
inherited class. The problem was that it sets AT_CellularContext::_is_connected flag but
earlier it was set as private member making it impossible to set in overwritten do_connect()
method.
This commit fixes the problem by changing _is_connected as protected enabling its use
in inherited class.
CellularContext now tries to get an IP address after connect and before
sending NSAPI_STATUS_GLOBAL_UP. Even if we don't the IP address from
the modem we will send NSAPI_STATUS_GLOBAL_UP and return success.
Modem has an ip address but for some reason some modems don't
give it to us.
If delete fails there is nothing we or application can do. There is no point
returning an error for this. This affects to AT_CellularContext::disconnect
not returning an error if context delete fails.
Disconnect was sent to all CellularContext classes even it concerned
one specific context. Some disconnect events are still sent to all
context classes. These event are coming from network and ment for all
context classes or event did not specify cid.
State machine has retry logic until device is attached to network.
After this CellularContext does the context activation e.g. connect.
There was no retry logic for context activation. Added logic to
CellularContext level so it's available for at and (upcoming)ril layers.
When using NetworkInterface::get_default_instance() application gets handle
to CellularInterface which is actually CellularContext derived from CellularInterface.
Application needs also handle to CellularDevice to open other interfaces.
Change usage of AT_CellularContext::stack_type_supported to
AT_CellularBase::get_property. This way we can rid of
targets overriding stack_type_supported and delete
unnecessary classes and simplify new targets.
Add override for the virtual method get_connection_status() inherited
from NetworkInterface. The method in the base class returns
NSAPI_STATUS_ERROR_UNSUPPORTED. The CellularContext has the member
_connection_status, which means that we could return this.
