Add some accessor macros for the ucontext:
...
* _UC_MACHINE_PC() - access the program counter
* _UC_MACHINE_INTRV() - access the integer return value register
* _UC_MACHINE_SET_PC() - set the program counter (this requires
special handling on some platforms).

* 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.
