Save preprocessor input and output files with save-temps
When using `GI_SCANNER_DEBUG=save-temps`, the temporary input file
to be preprocessed and temporary output file that is result of this
preprocessing are retained for debugging purposes. Use together with
`-v` option to actually determine names of those temporary files.
This should make it easier to determine the source of parsing errors,
like those described in the #247.
