continuing to call these "time tuples" is misleading at best.
Closes SF bug #671731; will backport to 2.2.x.

this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.

Imported the extension-registry dicts from copy_reg.py, in preparation for
tackling EXT[124].

from 68% to 77% (on Linux).

The script doesn't exercise the error branch that handles an evil

Also this script might not work on Jython in its current form.

From SF patch #662807.

cPickle_PyMapping_HasKey():  This extern function isn't used anywhere in
Python or Zope, so got rid of it.

outcome as __slotnames__ on the class.  (Like __slots__, it's not safe
to ask for this as an attribute -- you must look for it in the
specific class's __dict__.  But it must be set using attribute
notation, because __dict__ is a read-only proxy.)

   * Treat major, minor numbers of HTTP version as separate integers

_PyLong_NumBits(): moved the calculation of ndigits after asserting

huge.  On older Linux systems, the C library's strtod() apparently
gives up before seeing the end of the string when it sees so many
digits that it thinks the result must be Infinity.  (It is wrong, BTW
-- there could be an "e-10000" hiding behind 10,000 digits.)  The
shorter shuge still tests what it's testing, without relying on
strtod() doing a super job.

exception, ResourceDenied.  This is used to distinguish between tests that
are skipped for other reasons (platform support, missing data, etc.) from
those that are skipped because a "resource" has not been enabled.  This
prevents those tests from being reported as unexpected skips for the
platform; those should only be considered unexpected skips if the resource
were enabled.
