ba1315d0fb modutils/*: rewrite by Timo Teras <timo.teras AT iki.fi>
- a lot faster (linear algorithmic complexity, smaller memory foot print)
- a lot smaller (the old code was overly complicated)
- loading of aliases is now module-init-tools compliant
- blacklisting is done correctly (-b option added)
- module argument quoting done right
- depmod now correctly generates modules.symbols and modules.alias

ae84b11467 modprobe: fix for blacklisting
The patch makes the order of the alias/blacklist in modprobe.conf 
irrelevant (like module-utils' modprobe). In first patch the alias had 
to be defined before the blacklist which caused problems because the 
modprobe.conf file is read before /lib/modules/*/modules.alias.

The attatched patch will mark the blacklisted module itself rather than 
trying to find the alias that points to the blacklisted module and test 
this flag later in the alias resolving stage.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

4b5827a69b Patch from Yann Morin so modprobe won't return failure if the module gets
loaded while it's running (ala multi-device hotplug).

081e38483e Remove xcalloc() and convert its callers to xzalloc(). About half of them
were using "1" as one of the arguments anyway, and as for the rest a multiply
and a push isn't noticeably bigger than pushing two arguments on the stack.

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

c7ddefc062 Attempt at fixing bug 815 by upgrading bb_spawn() so that builtins are at
the start of the path.  (This should be under the same config option as
the standalone shell, but right now that's buried in the shell menu.)

Also add the ability to specify CONFIG_BUSYBOX_EXEC_PATH with /proc/self/exe
as an overrideable default.

deda6a5c0d - move #include busybox.h to the very top so we pull in the config
and eventual platform specific includes in early.
- remove two supposedly superfluous newlines from ...error_msg() in modprobe
  and use shorter boilerplate while at it.

2c351a8f98 - patch from Yann E. Morin: makes modprobe understand shell patterns
(especially '*') in module aliases, such as:
  "alias usb:v0582p0075d*dc*dsc*dp*ic*isc*ip* snd_usb_audio"

Fixes bug #889

a389651115 Remove bb_strlen() in favor of -fno-builtin-strlen. Saves as many bytes
as the old optimization did (actually does slightly better under gcc 4.0), and
