Actually we don't want to do this.  It is better to use the python dl
or os modules, so we will do that in a moment.

debian/changelog: finalise 4.5.0~iwj4

Backup: Honour CHIARK_BACKUP_SHAREDIR in snap/lvm script.

Backup: Add daft_sleep calls to snapshot code.

Nowadays udev (and other things) tend to randomly open new block
devices, and cause other kinds of trouble.  Bodge around this by
adding some sleeps.

Empirically tested on old-zealot.

Backup: No longer attempt to lvchange -a n the snapshot volume.

With modern LVM this would deactivate the source volume too.  So
instead it stops and prompts.  It's not necessary anyway given that we
are passing -f to lvremove.

Add debian/.debhelper to .gitignore.

cgi-fcgi-interp: Fix logger buffer-handling bugs.

cgi-fcgi-perl: wip new stderr logging, does not work properly right now

cgi-fcgi-interp: Send our own stage2 messages to syslog

And (sadly), provide the actual interpreter with /dev/null as stderr.

This is necessary because the caller expects us to behave like a
proper cgi script and close our stderr.  So we do that (as late as we
can).

cgi-fcgi-interp: Constify stage2

cgi-fcgi-interp: Remove use of err.h (preparation for syslog)

cgi-fcgi-interp: Demote its dependencies to Recommends.

cgi-fcgi-interp: Actually get run in ~ right

cgi-fcgi-interp: Provide -E option.

cgi-fcgi-interp: Provide -G option.

cgi-fcgi-interp: Reformat option table (nfc)

cgi-fcgi-interp: Make ident_sc global, and introduce ident_addstring (nfc)

cgi-fcgi-interp: Document accurately the default ident

cgi-fcgi-interp: mkdir ~/.cgi-fcgi-interp if necessary.

Finalise changelog for 4.5.0~iwj1

Drop a lot of -l options from xduplic-copier.

This gets rid of a lot of these:

On platforms without shared library support, it may be necessary to
edit the Makefile to put them back.
