Thanks to Chris Herborth, the thread primitives now have proper Py* names in the source code (they already had those for the linker, through some smart macros; but the source still had the old, un-Py names).

typedef void *PyThread_type_lock;
typedef void *PyThread_type_sema;
Added C++ support in thread.h; don't use signals if not strictly necessary, and when they are, use SIGKILL; when compiled with -DDEBUG, only print debug messages when "THREADDEBUG" is set in the environment.
