Specifies a block of data containing config overrides.
Version of override_config_file() which uses a block of data that has
already been read into memory. The length of the block has to be specified
in bytes. Example:
/* Force German as system language, Spanish keyboard map. */
const char *override_data = "[system]\n"
Note that this function and override_config_file() are mutually exclusive,
i.e. calling one will cancel the effects of the other.
