Fixed problem identified by Georg. The special-case in-place code for replace
...
made a copy of the string using PyString_FromStringAndSize(s, n) and modify
the copied string in-place. However, 1 (and 0) character strings are shared
from a cache. This cause "A".replace("A", "a") to change the cached version
of "A" -- used by everyone.
Now may the copy with NULL as the string and do the memcpy manually. I've
added regression tests to check if this happens in the future. Perhaps
there should be a PyString_Copy for this case?

both mystrtoul.c and longobject.c. Share the table instead. Also
cut its size by 64 entries (they had been used for an inscrutable
trick originally, but the code no longer tries to use that trick).

Heavily fiddled variant of patch #1442927 : PyLong_FromString optimization.
...
``long(str, base)`` is now up to 6x faster for non-power-of-2 bases. The
largest speedup is for inputs with about 1000 decimal digits. Conversion
from non-power-of-2 bases remains quadratic-time in the number of input
digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).
Speedups at various lengths for decimal inputs, comparing 2.4.3 with
current trunk. Note that it's actually a bit slower for 1-digit strings:

Added a slew of test for string replace, based various corner cases from
...
the Need For Speed sprint coding. Includes commented out overflow tests
which will be uncommented once the code is fixed.
This test will break the 8-bit string tests because
"".replace("", "A") == "" when it should == "A"
We have a fix for it, which should be added tomorrow.
