* Makefile: cosmetics

* socketmodule.c: get rid of makepair(); fix makesocketaddr to fix
  broken recvfrom()
* socketmodule: get rid of getStrarg()
* ceval.h: move eval_code() to new file eval.h, so compile.h is no
  longer needed.
* ceval.c: move thread comments to ceval.h; always make save/restore
  thread functions available (for dynloaded modules)
* cdmodule.c, listobject.c: don't include compile.h
* flmodule.c: include ceval.h
* import.c: include eval.h instead of ceval.h
* cgen.py: add forground(); noport(); winopen(""); to initgl().
* bltinmodule.c, socketmodule.c, fileobject.c, posixmodule.c,
  selectmodule.c:
  adapt to threads (add BGN/END SAVE macros)
* stdwinmodule.c: adapt to threads and use a special stdwin lock.
* pythonmain.c: don't include getpythonpath().
* pythonrun.c: use BGN/END SAVE instead of direct calls; also more
  BGN/END SAVE calls etc.
* thread.c: bigger stack size for sun; change exit() to _exit()
* threadmodule.c: use BGN/END SAVE macros where possible
* timemodule.c: adapt better to threads; use BGN/END SAVE; add
  longsleep internal function if BSD_TIME; cosmetics

-/* Interface for threads.
-
-   A module that plans to do a blocking system call (or something else
-   that lasts a long time and doesn't touch Python data) can allow other
-   threads to run as follows:
-
-	void *x;
-
-	...preparations here...
-	x = save_thread();
-	...blocking system call here...
-	restore_thread(x);
-	...interpretr result here...
-
-   For convenience, that the value of 'errno' is restored across the
-   the call to restore_thread().
-
-   The function init_save_thread() should be called only from
-   initthread() in "threadmodule.c".
-
-   Note that not yet all candidates have been converted to use this
-   mechanism!
