012c0a393a Newly-relaxed limits on random.randrange(). Also added some info about 
Karatsuba's better cache behavior with extremely large multiplicands.

dd32a91cc0 This is my patch 
[ 587993 ] SET_LINENO killer

Remove SET_LINENO.  Tracing is now supported by inspecting co_lnotab.

Many sundry changes to document and adapt to this change.

Tim predicts that we might as well call this CassandraWarning.

6000464d08 Added new function k_lopsided_mul(), which is much more efficient than 
k_mul() when inputs have vastly different sizes, and a little more
efficient when they're close to a factor of 2 out of whack.

I consider this done now, although I'll set up some more correctness
tests to run overnight.

d64c1def7c k_mul() and long_mul(): I'm confident that the Karatsuba algorithm is 
correct now, so added some final comments, did some cleanup, and enabled
it for all long-int multiplies.  The KARAT envar no longer matters,
although I left some #if 0'ed code in there for my own use (temporary).
k_mul() is still much slower than x_mul() if the inputs have very
differenent sizes, and that still needs to be addressed.

5af4e6c739 Cautious introduction of a patch that started from 
SF 560379:  Karatsuba multiplication.
Lots of things were changed from that.  This needs a lot more testing,
for correctness and speed, the latter especially when bit lengths are
unbalanced.  For now, the Karatsuba code gets invoked if and only if
envar KARAT exists.

cc8764ca9d Add C API PyUnicode_FromOrdinal() which exposes unichr() at C level. 
u'%c' will now raise a ValueError in case the argument is an
integer outside the valid range of Unicode code point ordinals.

Closes SF bug #593581.

085358a3e2 New functions for extension writers on Windows: 
PyErr_SetExcFromWindowsErr(), PyErr_SetExcFromWindowsErrWithFilename().

Similar to PyErr_SetFromWindowsErrWithFilename() and
PyErr_SetFromWindowsErr(), but they allow to specify
the exception type to raise. Available on Windows.

58cf361e35 docompare(): Another reasonable optimization from Jonathan Hogg for the 
explicit comparison function case:  use PyObject_Call instead of
PyEval_CallObject.  Same thing in context, but gives a 2.4% overall
speedup when sorting a list of ints via list.sort(__builtin__.cmp).
