9067f13be0 NOMMU re-exec trick shuld not depend on existence of "don't daemonize"
option for every affected applet (and dnsd, for example, don't have one).

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.

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.)

e15d7573a1 - move #include busybox.h to the very top so we pull in the config
and eventual platform specific includes in early.

c418d482ba - s/defined(__uClinux__)/BB_NOMMU/
This needs a second pass to:
+ add bb_daemon(unsigned char no_chdir, unsigned char no_close, const char*flag)
+ eventually globally export argc and argv, so we don't need to pass it to
  bb_daemon().

dac7ff15b7 - patch from Denis Vlasenko to add and use bb_xsocket() and to use

  Also use shorter boilerplate while at it.

dfba741457 Robert P. Day removed 8 gazillion occurrences of "extern" on function
definitions.  (That should only be on prototypes.)
