[Patches] Multiply sequences by longs

[Andrew M. Kuchling]

This patch makes 5L * 'b' legal; with the large-file patches, some
people have run into bugs in modules such as dumbdbm that don't expect
f.tell() to return a long int..

One inconsistency: 1231231232312341414L * 'a' gets an
OverflowError (long int too long to convert), while 312341414L * 'a'
raises a MemoryError.  I think this wouldn't be a problem in practice.

Documentation: a patch to the Reference and LibRef are required; there
may be other bits of the docs that need changing.  If this gets
accepted, I'll make patches for the docs.

Question: should other bits of the core be changed to accept long
ints?  Slicing, for instance, as in mylist[ 0L:5L ]?  (python-dev
topic, maybe?)
