and declare ssir as volatile. This avoids the problem of lost softints
should a hard interrupt cause a softint to be flagged while we are
clearing a different one.
Idea from atari mtpr.h, modified/optimized by me.
* Command line editing via editline(3) library.
* Context sensitive command and file completion, including remote files.
Enhancements to auto-fetch feature:
* Support for http:// URLs using the http protocol, including proxy HTTP
support via $htty_proxy if it's defined.
* The connection is kept open between successive files on the same host.
(obviously, this does not count for http requests.)
* Return value of ftp is 0 on no error, or the offset in argv[] of the file
which failed (i.e., argv[x] failed, ftp returns x).
* If the path in an ftp URL or classic format line has a trailing '/',
cd to the path and enter interactive mode. Fixes [bin/3011], albiet
requiring the user to help ftp in determining the operation.
Other changes:
* '-P port' works for normal ftp, and is the default for all classic style
auto-fetch transfers and for ftp URLs that don't specify the port.
(previously it would just work for the first xfer.)
* Some code moved into separated files along logical divisions.
* Editing and completion can be compiled out with -DSMALLFTP.
cute little trick where the zs interrupts are enabled as soon as the
zs driver has done its attachments. That allows a console break to
enter the debugger during the rest of autoconfiguration.
but if not then try to boot "netbsd", "netbsd.bak", "netbsd.old", and
"onetbsd" (in that order) until one is found or until the list of names
is exhausted.

be retried following a disconnection if this flag is set. The function
esc_select_unit() will set/clear this flag depending on when a selection
completed or not.
