* util/iobuf.c: (iobuf_open): initialize len
--
Cherry-pick 367b073ab5.
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.

* 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.

* openfile.c (overwrite_filep, make_outfile_name, open_outfile)
(open_sigfile): Use iobuf_is_pipe_filename to check for pipes so
that special filesnames are taken into account. This is bug 327.

locks. (release_dotlock): Don't act if we don't have any locks at all.
From Werner on stable branch.

the new iobuf_skip_reset. Orginal patch by Florian Weimer.

ttyio.c, w32reg.c: s/__MINGW32__/_WIN32/ to help building on native
Windows compilers. Requested by Brian Gladman. From Werner on stable

to avoid passing negative values and potential locale problems.
Problem noted by Christian Biere.

simple-gettext.c, errors.c, http.c, memory.c, secmem.c, ttyio.c: Edit all
preprocessor instructions to remove whitespace before the '#'. This is
not required by C89, but there are some compilers out there that don't
like it.
buffer; didn't worked at all. Reported by Thijmen Klok. From Werner on
stable branch.
* secmem.c (secmem_free, secmem_term): Use wipememory2() instead of
memset() to overwrite secure memory

Werner on stable branch.
