67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on

Basically it means that you cannot portably use
more that 32 option chars in one call anyway...

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.)

c9c1a41c58 A couple things that got tangled up in my tree, easier to check in both than 
untangle them:

Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the
signal list to that required by posix (they can specify the numbers for
the rest if they really need them).  (This is preparatory cleanup for adding
a timeout applet like Roberto Foglietta wants.)

Export the itoa (added due to Denis Vlasenko, although it's not quite his
preferred implementation) from xfuncs.c so it's actually used, and remove
several other redundant implementations of itoa and utoa() in the tree.

db1ab1aeb3 Top was catching sigterm (and fumbling sigint) so it could reset the terminal 
type on the way out, but the signal handler didn't exit.  Plus it did
unnecessary things with sigaction.  This code is overgrown and needs a serious
weed-whacking...

e2922e42a0 - make it C89 compatible; Declarations in the middle of a function is of course 
fine in C99, but it really serves no purpose other than breaking compilation
  on C89 compilers.
  Thanks to Rich Felker for pointing this out.

a6b5b60942 Fiddling with llist to make memory management easier. Specifically, the 
option to delete the contents of the list when we delete the list is a
good thing.

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
simplifies the code.

997650b972 From Denis Vlasenko: 
* CPU% = process[i].ticks/sum(process[i].ticks) * busy_cpu_ticks/total_cpu_ticks
* got rid of empty line under "Load average" line
  and used last line - +2 visible processes
* do not do float conversion of loadavg, just read it as string from /proc
* fix display on small screens
* dropped unused .stime, .utime fields
* a few variables were renamed
* style fixes
