Detect whether a gzip file is being passed to `unzip*` by testing the first bytes for the gzip magic bytes, and setting the decompression mode to `GUNZIP` or `INFLATE` according to the result. This enables gzip-only features like multi-member support to be used together with the `unzip*` autodetection support and thereby makes `gunzip*` and `unzip*` return identical results for gzip input again. Add a simple test for checking that features specific to `zlib.gunzip`, notably support for multiple members, also work when using `zlib.unzip`.
