2. Conditionalized a few small things which needed it.
3. Put PC98 X servers in their own menu, there are so many of them now.
4. Rampaged on the menus.c file in general, reformatting and cleaning up.
Not all mappings are supported, most languages come only with one
encoding since this should be sufficient to get up & running in using
sysinstall, and we are already pretty tight on space. (My previous
commit has already bumped the boot MFS size by another 50 KB for
this.)
This feature requires the `kbdcontrol -L' i've just committed. Plain
text keymaps and the entire scanner are overkill for sysinstall.
Also updated the list of available keymaps while i was at it.

any maps that may have them. If the YP_SECURE key is present, ypserv
will only allow access to the map from clients on reserved ports.
If the YP_INTERDOMAIN key is present, the server will do DNS lookups
for hostnames that it can't find in hosts.byname or hosts.byaddr.
This is the same as the -d flag (which is retained for backwards
compatibility) but it can be set on a per-map/per-domain basis.
Also modified /var/yp/Makefile to add YP_INTERDOMAIN to the hosts.*
maps and YP_SECURE to master.passwd.* maps by default.
map databases. Also document said flags in the man page.
Adding YP_INTERDOMAIN to a map causes ypserv(8) to do a DNS lookup
when a yp_match() on the map fails. (This affects only the hosts.by*
maps; for all other maps it's ignored.) The YP_SECURE entry causes
ypserv(8) to restrict access to the map so that only clients making
requests from reserved ports can get at it.
Our ypserv doesn't currently support these features so they're silently
ignored for the moment, but this will change. :)
find two users with the same UID (i.e. root and toor), but yp_mkdb(8)
forbits duplicate keys, so only one of them will end up in the *.byuid
maps (probably toor, since it comes after root in the template file).
If I asked rpc.yppasswdd(8) to change toor's password, it would update
the *.byname maps correctly, but incorrectly modify root's entry in
the *.byuid maps since the only matching record with UID=0 in those
maps belongs to root.
To fix this, we check that both the name and UID are correct before trying
to write new entries to the maps.

problem here is that when pwd_mkdb creates /etc/passwd, it turns
empty UID and GID fields into zeroes. To fix this, we check the
_PWF_UID and _PWF_GID bits in the pw_fields flag: if the bits
are not set, we print an empty field instead of a zero. This way,
you don't get zeroes in the UID or GID fields unless you explicit
want them.

For me, more often than not, the backgrounded syslogd daemon is not
yet ready to process log messages before other things (such as named)
want to log a heap of them. It seems that it's the O_SYNC writes of
the stuff coming in from /dev/klog that's the slowdown.
Anyway, instead of using the libc daemon, roll a modified version. This
one has a timeout. The child will wait for either the timeout to expire
or the child process to signal it to let it know that it's "ready" and
the /dev/log socket is set up and active, so it's safe to continue the
boot. It adds a small fraction of a second pause to the boot time, but on
the other hand the overall boot time is *quicker* since the disk is not
being thrashed while the log messages are getting written out synchronously
one by one while other daemons are loading in parallel.
The timeout is in case the child segfaults or something before becoming
fully operational.
SLIP/PPP devices, putting them before the others in the network device
selection menu.
2. Change "Other" to "URL" so as not to conflict with the keyboard accellerator
for the "OK" button in FTP site selection menu.
3. Detect the NULL last symbol in the name list and initialize the other
members correctly.
First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image

USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").

have it check to see that it doesn't contain any '/' characters. This
prevents possible silliness like ypcat "../../../kernel". We already
test the domain name for this in yp_validdomain(), and ypserv itself
tests the map name in yp_open_db(), but it doesn't hurt to be paranoid
and test for it in the generic access routine too. rpc.ypxfrd does not
test the map name for slashes, but it does call yp_access() with the
map name, so this removes a potential vulnerability from there.
Also make the tests for IPPORT_RESERVED a little more selective: make
sure it trips when map == master.passwd.*, prog == YPPROC and proc ==
YPPROC_XFR, and prog == YPXFRD_FREEBSD_PROG and proc == YPXFRD_GETMAP.
Also use IPPORT_RESERVED instead of hard-coded value.
