instead of individual components; initmodule3() now has doc string
argument as well

(a) support import NAME.NAME...NAME;
(b) support doc strings in modules, classes and function definitions

	use new instancebinop interface

	instancebinop, to support things like Rational * float; added
	documentation strings to classes and methods

	contains a pointer to the struct methodlist (which must be
	static); added attributes __name__, __doc__ and __self__

constant in code object if it is a string, else None

lib.tex: add libimp; remove bogus warning about lineii.
libmath.tex: document hypot().
libmd5.tex: rename md5.md5() to md5.new().
libposix.tex: document chown().
libposixfile.tex: openfile() instead of fileopen().
libsocket.tex: document gethostbyaddr().
libtypes.tex: add footnote explaining why readline() keeps the newline.
ref3.tex: correct typos, add back*quotes to index.
ref4.tex: don't use \verb inside footnote.
ref5.tex: explain repr() and str() and add them + back*quotes to index.
ref6.tex: correct typo, don't use \verb in footnote.
ref7.tex: don't use \verb in footnote.

bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().

Setup.in: clarified Tk comments somewhat.
structmodule.c: use memcpy() instead of double precision assignment.

floatobject.c: fix hash().
methodobject.c: support METH_FREENAME flag bit.

object.h: made sizes and refcnts signed ints.
stringobject.h: make getstrsize() signed int.
methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.

Makefile.in: run config.status in "make recheck".
configure.in: add test for hypot().
config.h.in, configure: since configure.in changed.
rest: the usual boring stuff.

	lookmapping() for empty dictionary

Note addition of gethostbyaddr() and improved repr() for sockets,
renaming of md5.md5() to md5.new(), and fixing of leaks in threads.

can now be NULL.
