Hello,
Attached patch makes file reader transparent. It should make adding new filters
to file reader easier.
- gzio.h is gone
- gzio is no more transparent, transparency is handled in grub_file_open()
- renamed GRUB_ERR_BAD_GZIP_DATA to GRUB_ERR_BAD_IOFILTER_DATA, it will be
used by other ios like xzio
What do You think about it?
