objects of its derived classes; allow anything that has an attribute
named "__privileged__" access to anything.
* object.[ch]: added hasattr() -- test whether getattr() will succeed.
Added $(SYSDEF) to its build rule in Makefile.
* cgensupport.[ch], modsupport.[ch]: removed some old stuff. Also
changed files that still used it... And made several things static
that weren't but should have been... And other minor cleanups...
* listobject.[ch]: add external interfaces {set,get}listslice
* socketmodule.c: fix bugs in new send() argument parsing.
* sunaudiodevmodule.c: added flush() and close().
function found as instance data.
* socketmodule.c: added 'flags' argument sendto/recvfrom, rewrite
argument parsing in send/recv.
* More changes related to access (terminology change: owner instead of
class; allow any object as owner; local/global variables are owned
by their dictionary, only class/instance data is owned by the class;
"from...import *" now only imports objects with public access; etc.)
* Added "access *: ...", made access work for class methods.
* Introduced subclass check: make sure that when calling
ClassName.methodname(instance, ...), the instance is an instance of
ClassName or of a subclass thereof (this might break some old code!)
yet). The class is now passed to eval_code and stored in the current
frame. It is also stored in instance method objects. An "unbound"
instance method is now returned when a function is retrieved through
"classname.funcname", which when called passes the class to eval_code.
