Remove the MU_STREAM_FD_AUTOCLOSE stream flag.

This is the default behavior now.  The reverse can be requested by
a special MU_IOCTL_FD,MU_IOCTL_FD_SET_BORROW ioctl.

* include/mailutils/stream.h (MU_STREAM_FD_AUTOCLOSE): Remove. This
is the default behavior now.
(MU_IOCTL_FD): New ioctl.
(MU_IOCTL_FD_GET_BORROW, MU_IOCTL_FD_SET_BORROW): New opcodes.
* include/mailutils/sys/file_stream.h (_MU_FILE_STREAM_FD_BORROWED): New flag.

* libmailutils/stream/file_stream.c (fd_close): Close the fd unless
_MU_FILE_STREAM_FD_BORROWED bit is set.
(fd_open): Clear the _MU_FILE_STREAM_FD_BORROWED bit.
(fd_ioctl): Handle MU_IOCTL_FD.
(mu_file_stream_create): Remove MU_STREAM_FD_AUTOCLOSE.

* ibmailutils/base/version.c (mu_print_options): Set borrow mode on the
temporary stdout stream.
* libmailutils/cfg/driver.c (mu_cfg_tree_reduce): Set borrow mode on the
temporary stderr stream.
* libmailutils/stdstream/strerr.c (mu_stdstream_strerr_create): Set borrow
mode on the stderr stream.
* libmailutils/tests/tempfile.c: set borrow mode on the temporary stream,
because it may be reopened later (verify mode).

* examples/mta.c: Remove MU_STREAM_FD_AUTOCLOSE.
* imap4d/io.c: Likewise.
* libmailutils/stream/prog_stream.c: Likewise.
* libmailutils/stream/socket_stream.c: Likewise.
* libmailutils/stream/temp_file_stream.c: Likewise.
* maidag/lmtp.c: Likewise.
* pop3d/extra.c: Likewise.

These will disappear when the corresponding utilities are rewritten to
use MU stdstream:

* mail/escape.c (quote0): set borrow mode on the output stream.
* mimeview/mimeview.c (display_file): set borrow mode on the input stream.

Likewise, these will disappear when MH uses MU stdstream:

* mh/anno.c (main): Set borrow mode on the input stream.
* mh/mh_init.c (mh_real_install): Likewise.
* mh/mh_whatnow.c (_whatnow): Likewise.
* mh/mhl.c (open_output): Set borrow mode on the output stream.
* mh/mhn.c (mhn_show,store_handler): Likewise.
