Adjust for sysinst move.

branches: 1.12.20; 1.12.50; 1.12.64;
Copy the Spanish language file into the ramdisk.

branches: 1.11.2;
Add French, German and Polish sysinstmsgs to all ramdisks that include sysinst
expect those where at least one of the language variants isn't built,
and those that are known not to have enough space (i386 ramdisk-tiny).
Files added to list.sysinst, list.sysinst.en is used when these files
cannot be added.
This might hit a size limit on another build - but I have no (sane) way of
testing it.

branches: 1.10.2;
Don't bother building var/db/obsolete/* files for the install media;
this stuff is in the base.tgz distribution, and it's better to have
postinstall fix it up than use the (dodgy) code in sysinst.

Add MAKE to PARSELISTENV, and specifically set MAKE=${MAKE} in
list.sysinst.
(Better fix to previous, but thanks to Warner for committing a
fix which then prodded me to improve it :)

all:
Use /var/db/obsolete instead of /etc/obsolete

etc/Makefile:
Create separate target "install-obsolete-files" to populate
/var/db/obsolete, instead of using "install-etc-files".

Makefile:
Add do-obsolete target, to run "cd etc && make install-obsolete-files",
and add this to BUILDTARGETS.
This moves the "obsolete files" creation from "distribution" to "build".


Per discussion with Andrew Brown.

install obsolete set lists as /etc/obsolete/%s not /dist/%s_obsolete

install /usr/bin/progress along with sysinst on all installation media
of all architectures that use sysinst.

branches: 1.5.2;
use ${DISTRIBDIR} instead of ${_SRC_TOP_}/distrib

add description and free space reminder

parselist.awk
- improve comments
- provide a general purpose variable replacement; replace contents of ${FOO}
with ENVIRON["FOO"].
- deprecate @MACHINE@ and @MACHINE_ARCH@ in favour of using ${MACHINE}
and ${MACHINE_ARCH} instead
- add errx() function; like err(), but doesn't print the line number
- invoke this script with various variables defined via PARSELISTENV

*/Makefile*
- use PARSELISTENV instead of POPULATEENV, and add variables like DESTDIR
- other minor tweaks

*/list*
- replace @MACHINE@ with ${MACHINE}

- cleanup image device creation: add Makefile.makedev & list.makedev,
remove dist/*, now that they're not needed.
if MAKEDEVTARGETS is set, use MAKEDEV.wrapper and makedev2spec.awk to
create an mtree specfile containing the devices that would be made with
"etc/etc.${MACHINE}/MAKEDEV $MAKEDEVTARGETS".
otherwise, copy etc/etc.${MACHINE}/MAKEDEV to dev/MAKEDEV (via list.makedev)
- add mtree.common; contains directories used by all images, and optional
entries for dist/*

add list containing files used by sysinst, including dummy files that
are used to set the default permissions in the generated mtree specfile
for files generated by makeobsolete.
