Factor out common stuff.

Give lots of room for further expansion of the sparc64 CD image

Exclude compat sets from ISO images that struggle to fit on a CD-ROM

When debug is excluded, also exclude the compat debug sets.

Consistently use ${RELEASEDIR}/${RELEASEMACHINE} instead of
${RELEASEDIR}/${MACHINE} (Paul Ripke)

Now that we do not force debug sets off install CDs any more, explicitly
set CDRELEASE_NODEBUG everywhere.

branches: 1.29.2; 1.29.4;
Introduce CDRELEASE_NODEBUG - if set, avoids putting debug sets in the
ISO image.

Set this for sparc64 install CDs - many of the supported machines have
SCSI CD drives and it is impossible to get DVD replacements for those.

This is a pitty, but in the end a working install medium is more worth
than debug sets (which can be downloaded later).

Initial pass to be unaffected by build umask on build artifacts
1. ${MKDIR} -> ${MKDIR} ${MKDIRPERM}
2. ${CP} -> ${INSTALL} ${COPY} -m <perm>

Obey MKKMOD=no.
From Rin Okuyama in PR install/50061.

Make sure to copy the language catalog files for sysinst, but do not
copy sysinst itself to / on the CD, and instead use the base version
for installation.

Do not default any CD_SETS - let the MD makefiles request them specifically.

2nd try: make amd64, i386, sparc64 and vax iso images use full sets.
While there fix an old bug that makefs used the build hosts /etc/group
and passwd information when creating the image.
Thanks to Andreas Gustafsson for extensive testing.

Revert previous untill fallout has been fixed.

Add a new simple method to put whole sets on CD images (instead of
listing single binaries or patterns) and use those for the existing
ISO images.

Add libpthread.so* - new lzma needs it.

Punt custom dhcpcd hooks in favour up upstream hooks

CD images need libarchive if MKBSDTAR is yes.

Include liblzma to unbreak gzip on the install CD. (Hi Joerg!)

Apply Joerg's changes to x86 CDs here alos:
Include libgcc_s.so symlinks in /usr/lib, so that binaries in /usr
linked against it actually work.

We realy should split this into MD and MI lists and share the MI one.

Add /usr/bin/getopt, it is needed by /usr/mdec/binstall.
Noticed by Jaime Fournier.

Adjust file lists for recent move:
usr/sbin/chown -> sbin/chown
usr/bin/chgrp -> bin/chgrp

Add /libdata/firmware and /usr/lib/libintl* to install CDROMs with
root on iso9660; fixes PR install/43692 and install/43693.

Um, as has been noted, INSTALL_FILE records what's installed if it's
done unprived, and that doesn't go down well on a re-build. So use
${INSTALL} ${COPY} instead to fix this problem.

Change use of ${CP} and ${CHMOD} to ${INSTALL_FILE}, so that if the
target is made un-writeable, the build won't bomb out during an
UPDATE build. OK'ed by martin@.

Ooops, do not try to create a symlink in a not-yet existing directory

Change the install CD to go to full multiuser mode. This clearly
separates the setup done by /etc/rc once, and the repeated stuff

Add an iso_image target (iso-image as a target name doesn't play well with
bsd.subdirs.mk) in distrib/makefile, which builds an iso image for $MACHINE
with binary sets, stored in ${RELEASEDIR}/iso. The image is bootable for:
alpha, amd64, cats, i386, pmax, sgimips, sparc, sparc64, sun3, vax.
mac68k/macppc no there yet because of missing feature in makefs.

call iso_image in distrib/ for iso-image in the top Makefile.

Enable basic command line editing in evbarm, sparc64 and vax installer shells

(Following the pattern in amd64)

When a user selects "exit installer" or hits ^Z in sysinst, the
calling install.sh runs a shell, plus shows a message indicating
they can type "exit" to return to the installer.

Add -E to the arguments to this shell, to enable command line editing,
(primarily for arrow keys, but basic emacs sequences will also work)

With the change of all the install.sh scripts in amd64, evbarm,
i386, sparc64 and vax are identical apart from NetBSD RCD tags and
the sysctl -nx kern.consdev check (some of the latter are definitely
either wrong, or have an incorrect comment attached. Will return
to later)

Switch device database to cdb(5). Rework ttyname(3) and ttyname_r(3) to
depend on new devname_r(3) as heart. Add /dev/pts magic directly to
devname(3). While it can lead to returning non-existing paths, the
behavior is more consistent that way. Drop caching layer in devname(3),
it doesn't buy anything for the common case of having access to the
database. Teach devname(3) proper fallback behavior of scanning /dev.
Create both old-style and new-style database for now in /etc/rc.d/sysdb.
