Kevin Bracey 355b45ade1 Cellular: Convert to Chrono 
Note that documentation for random_max_start_delay config setting has
been changed to indicate that the setting is in seconds, and always has
been. No functional change.

Kimmo Vaisanen 738f9fbcf6 Cellular: Disable AT traces when mbed-trace is disabled 
Earlier if mbed-trace was disabled but debug-at enabled, some AT trace codes were still
enabled causing unnecessary code size increase.

This commit fixes the issue that AT debug trace code is enabled only when both
mbed-trace.enable and cellular.debug-at are enabled.

Reduces binary size by about ~340bytes when mbed-trace is disabled but debug-at enabled.

Kimmo Vaisanen 214df550c0 Cellular: Check if serial is supported 
Baud rate can be only changed if BufferedSerial (or Serial in general) object is supported

Kimmo Vaisanen 584d54e955 Cellular: Fix ATHandler::read_string to handle delimiter inside string 
For example if input buffer includes:
+CCLK: "20/04/05,15:38:57+12"

read_string return "20/04/05,15:38:57+12" instead of "20/04/05"

Kimmo Vaisanen bd0f939277 Cellular: Remove support for multiple ATHandlers 
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.

Hugues Kamba 9e11e5b43d Cellular: Replace UARTSerial references with BufferedSerial 
`BufferedSerial` is `UARTSerial` renamed to convey the original purpose
of the class. It is the recommended buffered I/O serial class.

Antti Kauppila 5553d0acd3 ATHandler class refactor 
Refactored ATHandler class to have clear private and public elements
Also removed virtuality from ATHandler
Unittests updated to reflect changes

Antti Kauppila 36ca4d6516 ATHandler relocated 
ATHandler is part of our API so header file was moved under API folder and .cpp file was moved under device/ folder
ATHandler is used in both AT and PPP mode so it has been in slightly wrong place at the beginning.
