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).

/* (the result is no use of signals on SGI) */
The great renaming, phase two: all header files have been updated to use the new names exclusively, and the linker will see the new names. Files that import "Python.h" also only see the new names. Files that import "allobjects.h" will continue to be able to use the old names, due to the inclusion (in allobjects.h) of "rename2.h".

#ifndef Py_PROTO
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.
