[naviserver-devel] nsloopctl: replacing ns_ictl threads|cancel

[Stephen D. <sd...@gm...>]

I've imported the loopctl stuff and merged in the thread cancelation
functionality from nsd/tclinit.c, including a crash fix.  (Still needs
a man page)

If you used to do:

  set tids [ns_ictl threads]
  ns_ictl cancel $tid

You can now do:

  set tids [ns_loopctl threads]
  ns_loopctl abort $tid

I'm going to remove threads|cancel from ns_ictl.
