* Makefile adapted to changes below. * split pythonmain.c in two: most stuff goes to pythonrun.c, in the library. * new optional built-in threadmodule.c, build upon Sjoerd's thread.{c,h}. * new module from Sjoerd: mmmodule.c (dynamically loaded). * new module from Sjoerd: sv (svgen.py, svmodule.c.proto). * new files thread.{c,h} (from Sjoerd). * new xxmodule.c (example only). * myselect.h: bzero -> memset * select.c: bzero -> memset; removed global variable

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.
