Application uses a lot of text in the form of defines found in header
files to represent arguments and output.
Conversion helpers keep functionality of converting string as
bt_status_t or uuid in one place.

+/**
+ * Begin mapping section
+ *
+ * There are some mappings between integer values (enums) and strings
+ * to be presented to user. To make it easier to convert between those two
+ * set of macros is given. It is specially useful when we want to have
+ * strings that match constants from header files like:
+ * BT_STATUS_SUCCESS (0) and corresponding "BT_STATUS_SUCCESS"
+ * Example of usage:
+ *
+ * INTMAP(int, -1, "invalid")
+ * DELEMENT(BT_STATUS_SUCCESS)
+ * DELEMENT(BT_STATUS_FAIL)
+ * MELEMENT(123, "Some strange value")
+ * ENDMAP
+ *
+ * Just by doing this we have mapping table plus two functions:
+ * int str2int(const char *str);
+ * const char *int2str(int v);
+ *
+ * second argument to INTMAP specifies value to be returned from
+ * str2int function when there is not mapping for such number
+ * third argument specifies default value to be returned from int2str
+ *
+ * If same mapping is to be used in several source files put
+ * INTMAP in c file and DECINTMAP in h file.
+ *
+ * For mappings that are to be used in single file only
+ * use SINTMAP which will create the same but everything will be marked
+ * as static.
