/**
* FARF macro used for logging
*
* Compile time logging options
* -----------------------------
*
* Logging is controlled via conditional compilation. A FARF
* level should be defined to 1 for FARF macros to be compiled
* in. For example:
*
* #define FARF_LOW 1
* #include "HAP_farf.h"
*
* FARF(LOW, "something happened: %s", (const char*)string);
*
* If FARF_LOW is defined to 0, as it is by default, the above
* FARF string will not be compiled in, if it is defined to 1 it
* will be compiled in. Users can also define their own custom
* levels. For example:
*
* #include "HAP_farf.h"
* #define FARF_MYTRACE 1
* #define FARF_MYTRACE_LEVEL HAP_LEVEL_LOW
*
* FARF(MYTRACE, "custom trace in file %s on line %d", __FILE__, __LINE__);
*
* The LEVEL define tells FARF what logging level to
* use. These are mapped to their diag level counterparts, in
* the above example the message will be logged to diag's LOW
* level.
*
* Messages logged with ALWAYS level are always compiled in and logged
* ------
*
* When building the Debug variant or builds defining _DEBUG the
* following FARF levels will be enabled:
*
* HIGH
* ERROR
* FATAL
*
*
*
* Run time logging options
* --------------------------
*
* In order to enable run-time logging (logging that can be enabled / disabled
* at run-time), the FARF_RUNTIME_* macros should be used.
*
* Log messages sent with these macros are compiled in by default. However by
* these messages WILL NOT be logged by default. In order to enable logging,
* the FASTRPC process will need to either call the
* HAP_SetFARFRuntimeLoggingParams() API, or by adding a <process_name>.farf
* file to the HLOS file system with the appropriate contents.
*
* #include "HAP_farf.h"
* FARF(RUNTIME_HIGH, "something happened: %s", (const char*)string);
*
