Newer GCC warns against possible alignment difference of pointers.
This change can silence those warnings.

e7cbce8fb2 avoid future chance of using uninitialized memory
* util/iobuf.c: (iobuf_open): initialize len

--

Cherry-pick 367b073ab5f439ccf0750461d10c69f36998bd62.

In iobuf_open, IOBUFCTRL_DESC and IOBUFCTRL_INIT commands are invoked
(via file_filter()) on fcx, passing in a pointer to an uninitialized
len.

With these two commands, file_filter doesn't actually do anything with
the value of len, so there's no actual risk of use of uninitialized
memory in the code as it stands.

However, some static analysis tools might flag this situation with a
warning, and initializing the value doesn't hurt anything, so i think
this trivial cleanup is warranted.

f10b184e48 gpg: Limit the nesting level of I/O filters.
* until/iobuf.c (MAX_NESTING_FILTER): New.
(iobuf_push_filter2): Limit the nesting level.
--

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.
