Create JERRY_LOG macros #68
Description
Currently the only way to print debug information is using 'fprintf' with JERRY_NDEBUG. It would be helpful to do some logger macros to wrap NDEBUG and fprintf at least. The possibility of setting different debug levels can make this more useful.
Example:
JERRY_DPRINT("This is a first level debug message!", variables);
JERRY_DDPRINT("This is a second level debug message!", variables);
JERRY_DDDPRINT("This is a third level debug message!", variables);
