thorpej 68723a995b * Shuffle some data structures so, and add a flags word to ksiginfo_t. 
Right now the only flag is used to indicate if a ksiginfo_t is a
  result of a trap.  Add a predicate macro to test for this flag.
* Add initialization macros for ksiginfo_t's.
* Add accssor macro for ksi_trap.  Expands to 0 if the ksiginfo_t was
  not the result of a trap.  This matches the sigcontext trapcode semantics.
* In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal.
  Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles
  the case of non-trap-generated signals that have a > 0 si_code.

This patch fixes a signal delivery problem with threaded programs noted by
Matthias Drochner on tech-kern.

As discussed on tech-kern.  Reviewed and OK's by Christos.
