Remove unneeded string copy.
Allow to set ''(empty string values) internal/input/output_encoding for better compatibility. i.e. Runtime INI value changes.
More compliance to the RFC. Improve/add encoding handling tests. i.e. Rather than set encoding automagic way, detect it.

Fixed Bug #66987 Memory corruption in fileinfo ext (bigendian)

On little endian:
	map->p == php_magic_database
	map->magic[i] = pointer into the map

	map->p == NULL
	map->magic[i] = pointer to allocated memory

On big endian (ppc64, s390x, ...):
	map->p != php_magic_database and map->p != NULL
        map->magic[i] = pointer into a copy of the map

Trying to efree pointer in the later cause memory corruption
Thanks to dkatulek / Red Hat for the report.
