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:
GCC:
Total Static RAM memory (data + bss): 29360(+296) bytes
Total Flash memory (text + data): 130660(-832) bytes
ARM:
Total Static RAM memory (data + bss): 261554(+8) bytes
Total Flash memory (text + data): 127573(-1193) bytes
IAR:
Total Static RAM memory (data + bss): 25479(+296) bytes
Total Flash memory (text + data): 102418(-527) bytes
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.
Removed CellularBase and AT_CellularBase from cellular stack and updated both code and unittests accordingly.
Moved property handling into AT_CellularDevice
