Kimmo Vaisanen a2857bac97 Cellular: Improve ATHandler AT traces 
Original AT traces had several issue:
- Can be overwritten by other traces (printf/mbed-trace)
- No way to know which direction message was going (TX or RX)
- <cr> and <ln> characters were not visible in trace
etc.

This commit addresses those issues using mbed-trace and showing separately
each filehandle write and read.

Teppo Järvelin a12f8cd5db Cellular: don't allow ATHandler read/write if filehandle not usable 
For example after going to ppp mode we must block at write and
read as filehandle is not usable.

Teppo Järvelin ec73c8a9c7 Cellular: fix connect-disconnect sequence called many times 
Fix syncing back to at mode after ppp disconnect.
Fix AT_CellularContext flags and states to allow new connect after disconnect.
Fix that state machine is not reseted in disconnect is it's running (might be
running because of another context or new connect already started).

Jari Poyhonen b6a0892e86 Cellular: clean sensitive information from trace 
Information removed from the cellular subsystem trace log:
* SIM pin
* APN username and password

Added get_debug() to ATHandler.h to get the current trace state in order
to support suspend/resume of trace output.

Teppo Järvelin b0d37ebec4 Cellular: Removed unnecessary checks after new 
After this change we were able to change methods
ATHandler::set_urc_handler and CellularDevice::set_ready_cb to void
and simplify error handling.

Mirela Chirica 806e95cf67 Cellular: Rewrite AT handler consume to tag 
If sequence from buffer contains tag but symbol before tag is same as
first symbol of the tag, then the tag wasn't detected.

For example, "\r\n" tag was not found from "\r\r\nOK" sequence.

Ari Parkkila 9bdeb68e74 Cellular: Updated debug prints, and network registration return value 
Updated cellular debug trace prints:
 - Removed unnecessary prints.
 - Tracing more in DEBUG level.
 - Read/write bytes not printed on big packets.
 - Signal quality (RSSI) traced to log network problems.
 - Dismissed AT data is traced.
 - Modem type and firmware version are traced.

Network registration returns NotRegistered instead of StatusNotAvailable,
because that's not in 3GPP TS 27.007.

Kevin Bracey 1ef213ec89 Clean up Thread deprecation warnings 
Static Thread methods and signal methods have been deprecated. Remove
all references in the main code, and most of the tests. Some tests of
the deprecated APIs themselves remain.
