Werner Koch 35e40e2d51 gpg: Limit the nesting level of I/O filters.
* common/iobuf.c (MAX_NESTING_FILTER): New.
(iobuf_push_filter2): Limit the nesting level.

* g10/mainproc.c (mainproc_context): New field ANY.  Change HAVE_DATA
and ANY_SIG_SIGN to bit fields of ANY.  Add bit field
UNCOMPRESS_FAILED.
(proc_compressed): Avoid printing multiple Bad Data messages.
(check_nesting): Return GPG_ERR_BAD_DATA instead of UNEXPECTED_DATA.

This is a more general fix for the nested compression packet bug.  In
particular this helps g10/import.c:read_block to stop pushing
compression filters onto an iobuf stream.  This patch also reduces the
number of error messages for the non-import case.
