61a91af63d kill: optimizations for single-applet build 
* Fix a bug with a configuration in which the shell's kill builtin
  would be mistreated as a killall command (i.e. '-q' works, and
  'kill process_name' succeeds when it shouldn't):

    CONFIG_ASH_JOB_CONTROL=y
    CONFIG_HUSH_KILL=y
    # CONFIG_KILL is not set
    CONFIG_KILLALL=y
    # CONFIG_KILLALL5 is not set

* Optimize out unneeded code when the relevant applets are not
  selected.

* Move kbuild lines about shells' kill builtins from Kbuild.src to
  kill.c, to accompany the new HAVE_SH_KILL macro. I hope this would
  make maintanence a little bit easier.

However their code was unusably different from sysvinit original.
Run tested.

16bbb20089 Random cleanup hanging around my tree. 2006-09-12 20:28:34 +00:00

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.

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

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

Here is a patch for kill that I posted long ago, but forgot about
until today.  This allows kill to specify a negative process/group
(such as -1).  The shell already had this fix applied by Vodz some
time ago.
