** Function:        initializeGlobalAppLogLevel
**
** Description:     Initialize and get global logging level from .conf or
**                  Android property nfc.app_log_level.  The Android property
**                  overrides .conf variable.
**
** Returns:         Global log level:
**                  BT_TRACE_LEVEL_NONE    0        * No trace messages to be generated
**                  BT_TRACE_LEVEL_ERROR   1        * Error condition trace messages
**                  BT_TRACE_LEVEL_WARNING 2        * Warning condition trace messages
**                  BT_TRACE_LEVEL_API     3        * API traces
**                  BT_TRACE_LEVEL_EVENT   4        * Debug messages for events
**                  BT_TRACE_LEVEL_DEBUG   5        * Debug messages (general)
