Figure out where we need utf8 support, and add it.

+ The command shell situation is a mess. We have two different
shells that don't really share any code, and the "standalone shell" doesn't
work all that well (especially not in a chroot environment), due to apps not
being reentrant.
- lash is phased out. hush can be configured down to be nearly as small,
- but less buggy :)
- init
- General cleanup (should use ENABLE_FEATURE_INIT_SYSLOG and ENABLE_FEATURE_INIT_DEBUG).
Do a SUSv3 audit
Look at the full Single Unix Specification version 3 (available online at
"http://www.opengroup.org/onlinepubs/009695399/nfindex.html") and
New debug options:
-Wlarger-than-127
Cleanup any big users
- -Wunused-parameter
- Facilitate applet PROTOTYPES to provide means for having applets that
- do a) not take any arguments b) need only one of argc or argv c) need
- both argc and argv. All of these three options should go for the most
- feature complete denominator.
Collate BUFSIZ IOBUF_SIZE MY_BUF_SIZE PIPE_PROGRESS_SIZE BUFSIZE PIPESIZE
make bb_common_bufsiz1 configurable, size wise.

Text buffer support.
Several existing applets (sort, vi, less...) read
- a whole file into memory and act on it. There might be an opportunity
- for shared code in there that could be moved into libbb...

Memory Allocation
We have a CONFIG_BUFFER mechanism that lets us select whether to do memory
FEATURE_CLEAN_UP
This is more an unresolved issue than a to-do item. More thought is needed.
- Normally we rely on exit() to free memory, close files, and unmap segments
+ Normally we rely on exit() to free memory, close files and unmap segments
for us. This makes most calls to free(), close(), and unmap() optional in
busybox applets that don't intend to run for very long, and optional stuff
can be omitted to save size.
For right now, exit() handles it just fine.

Minor stuff:
watchdog.c could autodetect the timer duration via:
if(!ioctl (fd, WDIOC_GETTIMEOUT, &tmo)) timer_duration = 1 + (tmo / 2);

possible code duplication ingroup() and is_a_group_member()

- Move __get_hz() to a better place and (re)use it in route.c, ash.c, msh.c
+ Move __get_hz() to a better place and (re)use it in route.c, ash.c

See grep -r strtod
Alot of duplication that wants cleanup.

in_ether duplicated in network/{interface,ifconfig}.c
---
+ unify progress_meter. wget, flash_eraseall, pipe_progress, fbsplash, setfiles.
Code cleanup:
---
vdprintf() -> similar sized functionality

+(TODO list after discussion 11.05.2009)
+
+* shrink tc/brctl/ip
+ tc/brctl seem like fairly large things to try and tackle in your timeframe,
+ and i think people have posted attempts in the past. Adding additional
+ options to ip though seems reasonable.
+
+* add tests for some applets
+
+* implement POSIX utilities and audit them for POSIX conformance. then
+ audit them for GNU conformance. then document all your findings in a new
+ doc/conformance.txt file while perhaps implementing some of the missing
+ features.
+ you can find the latest POSIX documentation (1003.1-2008) here:
+ http://www.opengroup.org/onlinepubs/9699919799/
+ and the complete list of all utilities that POSIX covers:
+ http://www.opengroup.org/onlinepubs/9699919799/idx/utilities.html
+ The first step would to generate a file/matrix what is already archived
+ (also IPV6)
+
+* ntpdate/ntpd (see ntpclient and openntp for examples)
+
+* implement 'at'
+
+* rpcbind (former portmap) or equivalent
+ so that we don't have to use -o nolock on nfs mounts
+
+* check IPV6 compliance
+
+* generate a mini example using kernel+busybox only (+libc) for example
+
+* more support for advanced linux 2.6.x features, see: iotop
+ most likely there is more
+
+* even more support for statistics: mpstat, iostat, powertop....
