* Update magic implementation from openbsd to 0e59d0d commit * Various refactoring of the original code to use RzUtil primitives instead of the custom implementation * Remove static variables from the original code * Remove Queue, regex_t and use RzList, RzRegex instead * Remove unneeded code from the original implementation * Use RZ_LOG_* macroses instead of the custom logging of the original code * Use rz_endian primitives where appropriate * Use os-specific functions where appropriate * Move magic functions to internal header
