Mark Favas was quick to note that the last checkin divides by zero

when n == 0... So divide by a->ob_size instead which was already

Fix bug discovered by John W. Shipman -- when the width of a format
...
specifier came from an int expression instead of a constant in the
format, a negative width was truncated to zero instead of taken to
mean the same as that negative constant plugged into the format. E.g.
"(%*s)" % (-5, "foo") yielded "(foo)" while "(%-5s)" yields "(foo )".
Now both yield the latter -- like sprintf() in C.

1. Fixes float divmod so that the quotient it returns is always an integral
value.
2. Fixes float % and float divmod so that the remainder always gets the
right sign (the current code uses a "are the signs different?" test that
doesn't work half the time <wink> when the product of the divisor and the
remainder underflows to 0).

Fix a problem with Vladimir's PyFloat_Fini code: clear the free list; if

a block cannot be freed, add its free items back to the free list.
This is necessary to avoid leaking when Python is reinitialized later.

Fix a problem with Vladimir's PyInt_Fini code: clear the free list; if

a block cannot be freed, add its free items back to the free list, and
add its valid ints back to the small_ints array if they are in range.

Vladimir has restructured his code somewhat so that the blocks are now

represented by an explicit structure. (There are still too many casts
in the code, but that may be unavoidable.)
Also added code so that with -vv it is very chatty about what it does.
