The function wpa_config_get_line() is used by the wpa_supplicant config file parser to retrieve the next non-comment non-blank line. We'll need the same kind of functionality to implement the file-based external password backend, so as a preparatory step this commit extracts the function into its own standalone file in the utils package. No functional changes are expected from this commit. Signed-off-by: Patrick Steinhardt <ps@pks.im>
