common: Fix iobuf API of filter function for alignment.
* common/iobuf.h (IOBUFCTRL_DESC): Change the call semantics. * common/iobuf.c (iobuf_desc): Add the second argument DESC. (print_chain, iobuf_close, do_open, iobuf_sockopen, iobuf_ioctl) (iobuf_push_filter2, pop_filter, iobuf_write_temp): Change calls of iobuf_desc. (file_filter, file_es_filter, sock_filter, block_filter): Fill the description. * common/t-iobuf.c (every_other_filter, double_filter): Likewise. * g10/armor.c, g10/cipher.c, g10/compress-bz2.c, g10/compress.c, g10/decrypt-data.c, g10/encrypt.c, g10/mdfilter.c, g10/progress.c, g10/textfilter.c: Likewise.
Newer GCC warns against possible alignment difference of pointers.
This change can silence those warnings.
