g10: Fix iobuf API of filter function for alignment.
* include/iobuf.h (struct iobuf_struct): Remove DESC. * util/iobuf.c (iobuf_desc): New. (print_chain, iobuf_close, iobuf_open, iobuf_fdopen, iobuf_sockopen) (iobuf_create, iobuf_append, iobuf_openrw, iobuf_ioctl) (iobuf_push_filter2, pop_filter, underflow): Use iobuf_desc. (file_filter, sock_filter, block_filter): Fill the description. * g10/armor.c, g10/cipher.c, g10/compress-bz2.c, g10/compress.c, g10/encode.c, g10/encr-data.c, g10/mdfilter.c, g10/pipemode.c, g10/progress.c, g10/textfilter.c: Likewise.
Newer GCC warns against possible alignment difference of pointers.
This change can silence those warnings.
