nfo conversion of busybox – child's play due to the recent changes in trunk

copy trunk/freewrt r3264 into a new branch for making the nfo system
because upgrading the old adk branch would be a hell more work

make postinstall scripts require mksh as functions.sh does
(how good it's in lbin/ anyway)

part Ⅱ – simplify busybox config, ok wbx@
from now on, you can select a smaller and a fuller busybox, like mksh;
if you want fewer applets, hand-edit the config, we won't prevent you,
but shan't support it in the ADK any more; if you want more applets,
please talk to me and I'll see if they can be included in the list

we still have a problem regarding duplicate binaries (ip, free, tar, …)
which could be solved with dpkg diversions if ipkg supports them;
for now just consider busybox a non-upgradable package if you have any
of these installed

first of a series of commits I'd suggest to not test until I did:

remove busybox ash and the other shells (hush, lash, msh); always
use mksh by default, as /bin/sh, /bin/ash symlink, /bin/mksh native,
and default admin login shell unless bash or zsh are selected

mksh is a superset of ash (I didn't find anything busybox ash can
do that mksh can't), and the upcoming mksh R30 will be even smaller
in -DMKSH_SMALL mode (but that one will lack vi editing mode)

ok wbx@

we planned this for 1.2, but it will greatly help the nfo conversion
and users request shells they can actually use if they don't have a
webinterface handy

hi, 
we had a longer discussion about this in the past. Today a Unix sysadmin
convinced me to change the policy and add ifconfig and route back as default.
People who need more space, should just disable it in the ADK, they know how to use it and know how to disable it. "new" users, but old unix people, just need
route/ifconfig, because it works on every other unix.

if fwifupdown, don't ifupdown ourselves, part I

changed location of network files to /etc/network
fixed bug in /etc/network/plugins/lladdr

fix a bunch of rc.conf addition bugs

make netmsg split overly long msgs to multiple pkgs

sorry, but we need help to test the new ifupdown scripts. 
THIS WILL BREAK STUFF, PLEASE ONLY USE TRUNK NOW IF YOU KNOW HOW TO USE
SERIAL CONSOLE OR FAILSAFE.

Sometimes test first is not applicable. brcm-2.4 is tested by Christian.

Extra reboot for jffs2 is obsolete, we have adapted the OpenWrt method.

the treebreaker ☺

overhaul the fetch'n'checksum system to be more bsd-like
• make fetch, make checksum supported
• future expansion possibilities already prepared:
  – more distfiles than just one
  – check sizes of downloaded files (size matters!!!!!111)
  – more hashes than just MD5
  – recursive fetch/checksum targets
  – PERMIT_{SOURCES,DISTFILES}=Yes/«reason» – licence issues
• download.pl dies

quirks:
• GNU make only has a poor excuse for a .for loop
• some things (esp. toolchain and target/linux) now have
  a ${WRKDIR} where they didn't have it before
• ${WRKDIR}/.checksum_done – no comment… it was necessary
  because otherwise everything will get rebuilt every time
  (did I mention that GNU make sucks?)
• I had troubles tracking the dependency problems down
  because GNU make, unlike BSD make, doesn't have good debugging
• DISTFILES -> FULLDISTFILES
• DL_DIR -> DISTDIR
• PKG_SOURCE -> DISTFILES
• PKG_SOURCE_URL -> MASTER_SITES
• no @SF and @GNU any more, use BSD network.template syntax
  (feel free to add more master sites)
• GNU make doesn't really strip whitespaces from variables…
  (did I mention how much better BSD make is?)
• echo 'LOCAL_DISTFILES=/path/to/distfiles' >>${TOPDIR}/prefs.mk
  will save the need to download 'em, Closes: #102
• MASTER_SITES now *must* have the trailing slashes (there may be
  a few that don't and a few with double ones, please fix them)

I've tested that a normal build (unchanged .config from the default) works
on GNU/Linux. There's definitively room for improvement, but most of that
will come with the NFO system only. Fixes appreciated.

• base-files/files/etc/init.d/rcK, base-files/files/etc/init.d/rcS:
  do correct shebang processing, like the BSD kernel and mksh: get
  first line of script to run if it begins with "#!", strip that and
  any leading space/tab off, then get shell name (terminates with
  space/tab/end of string) and shell argument quoting according to
  unix common proceedings; use /bin/sh as interpreter if none could
  be found
• mk/package.mk: ensure all init scripts are 0755 by default
• busybox: flesh out inetd init script, so that all init scripts in
  FreeWRT either can be found with -path \*/init.d/\* or -name \*.init
• other packages: add #!/bin/sh shebang line to init scripts¹, bump dashver

¹) change this to /bin/ash if you use ash-specific features that mksh
   can also do; never use ash-specific features that mksh cannot do (are
   there any?), change to /bin/mksh if you use mksh-specific features
   and add a run-time dependency on mksh in that case

forgot one

some install scripts didn't work properly because they
didn't specify sh explicitly

rc.conf support for inetd and rdate

rtrim /etc/network/interfaces on read; untested; Closes: #293

these shall not be executable nor use absolute pathnames,
since perl doesn't always live in /usr/bin (e.g. NetBSD®)

by request of wbx@, add a clause
| autostop) ;;
to all cases inside all init scripts so that we won't have any
errors on shutdown. the alternative would be
| autostop) exec $0 stop "$@" ;;
of course, for packages that want it.

also bump all patchlevels again *sigh*

attention: mechanical commit. please read diff and fix breakage
if you are package maintainer.

fix the remainder of the init script fubar

run-time test succeeded after prodding and serial console help by wbx@

by request of wbx@:

make it possible for users to do
| /etc/init.d/<foo> restart
instead of having to do
| /etc/init.d/S*<foo> restart
by moving the order into a magickal™ comment.

Untested.

Also remove the svn:executable properties, because rcS and rcK will
always call them with /bin/sh, and bump dashvers accordingly.

udhcpd made usable

This conditionally adds an init script and a default config
to the busybox package if the udhcpd config option is activated.

- upgraded to 1.4.2
- removed patches integrated in 1.4.2
- heading forward to 1.5.0 which is already running an a test machine ;-)

time to break trunk. 

* update to OpenWrt brcm-2.4 patch, wl driver and diag driver
* fix failsafe mode to use new hotplug method
* rework of mk/kernel-build.mk to use .config instead of stampfiles
* simplify mk/kernel*.mk to use $(FS) instead ifeq/else crap

a lot of small stuff.

tested and verified to boot at least on 
- Netgear WG634u
- Linksys WRT54GS v1.0
- Asus WL500gP

Only basic lan and wlan stuff (none encryption, wep) are tested.

PLEASE update only on NON-PRODUCTIVE routers with serial access.
HELP to test the new backend code for BRCM-2.4!

coerce busybox into building on BSD: remove “compress usages”
this wouldn't work because it required building a (small) subset
of busybox for the build system (with ${HOSTCC}) but didn't
autoconf for the include files etc. existing on it (because the
build system isn't necessarily glibc/Linux).

tested on mirbsd
happy wbx@

by request of wbx@, upgrade to fwcf 1.03, add reboot hook, etc.
somewhat tested on my asus wl-500g, both mksh and ash

fix PR#242 but more cool ;)
if we use BUSYBOX_CONFIG_DIFF, retain the functionality

fix ipkg problem #220

bump dash-ver, should've been done in -r2037

if ifupping a dhcp interface, ip link set up it first, if we use
the 'ip' utility and call udhcpc afterwards

fixes¹ at least my "WAN iface doesn't do any DHCP request" issues
and won't blow up other use cases

ok² to commit n0-1@

¹) yep, run-time tested
²) yep, peer review

add http://busybox.net/downloads/fixes-1.4.1/busybox-1.4.1-binhex.patch
from nbd@OpenWrt via IRC

bump package patchlevel, svn -r1929 contains a fix to the
| logread: can't find syslogd buffer: No such file or directory
problem

merged busybox upgrade to 1.4.1 from branch
more testing needed!

* added /etc/network/if-up.d/ipv6 with the following new ipv6 options for
  every interface listed in /etc/network/interfaces
  - IPV6-FLUSH to disable ipv6 on a specific interface (via ip -6 addr flush)
  - IPV6-AUTOCONF to disable/enable autoconf
  - IPV6-ACCEPT-RA to disable/enable router announcements
  - IPv6-ACCEPT-REDIRECTS to disable/enable redirects
  - IPv6-FORWARDING to disable/enable forwarding (normally disabled)
  - IPV6-USE-TEMPADDR to disable/enable a temporary address

merged from branches/common-adk 1310:1685

the following packages are not converted yet:
* alsa
* asterisk
* pmacct
* zaptel
* elinks
* libgd
* lua
* mypackage
* openser
* php*
* snort*
* tmsnc

additionally, freeradius doesn't compile.

happy fixing :P

ccache integration, makefile fixes

bumb to new version (untested)

busybox upgrade to 1.2.1

there is no 'pre-down' hook in ifupdown

sync with freewrt_1_0 branch. It was a little bit to early to branch,
but now everybody can work again. New smaller stuff can be committed 
directly in trunk.
Bigger stuff, like a new architecture or a new board should be
developed via a separate branch. Kernel and compiler updates, too.

Any bugfixes or security updates should go into branch and trunk. 

Still send me a patch first and do not commit directly into the branch.

- added two hook scripts for ifupdown to configure vlans and bridges
- added hook scripts to Makefile
- added rc.conf query to broadcom network.init script

use up commands to configure wireless, pre-up scriüpt does not work correctly

fix ifup dirnames

* add a generic network init script which is using busybox ifup/ifdown
* move ifup/ifdown with nvram calls to webif package
* add specific dnsmasq.conf and startup script for dnsmasq for webif
* add version file

This unbreaks DNS/DHCP options in Webif. Even WPA/WPA2 seems possible
if you install broadcom-nas package. I have no WPA/WPA2 enabled box
or operating system to test..

tg@ will add some rc.conf checks so that either webif network 
configuration is used or ifup/ifdown from busybox

add separate crond script to busybox package, do not startup by default. use /etc/rc.conf to activate

major package Makefile cleanup. remove mostly-clean, add licence header, always use RSTRIP varibale for stripping, rename some init scripts, indent

let the user decide which of the available shells he
wants as /bin/sh - not only these included with busybox

(ash and mksh are probably the only ones which will
work, but like this I won't affect any existing con-
figuration)

* whitespace cleanup, while here
* move WRKDIR and DISTFILES definition into PKG_template
* define WRKDIR via parent BUILD_DIR instead of going up from WRKSRC
* use a sub-directory as WRKDIR, like BSD
* rename PKG_BUILD_DIR into WRKBUILD
* define WRKBUILD relative via WRKDIR
* rename PKG_INSTALL_DIR into WRKINST
* fix a few dependencies
* make use of common cases in the definition of WRKBUILD and
  WRKINST, removing many redundant lines
* use WRKDIR instead of BUILD_DIR in places where the latter
  was used previously
* while here, remove PKG_CAT stuff

this only affects packages, for now

no support for busybox snapshot, we use releases

add OpenWrt trunk revision 3830.
