Issue #8014: Fix PyLong_As<c-integer-type> methods not to produce an
internal error on non-integer input: they now raise TypeError instead.
This is needed for attributes declared via PyMemberDefs.

previously failing test_structmember.py tests.

Issue #3166: Make long -> float (and int -> float) conversions
correctly rounded, using round-half-to-even. This ensures that the
value of float(n) doesn't depend on whether we're using 15-bit digits
or 30-bit digits for Python longs.

Issue #5512: speed up the long division algorithm for Python longs.
The basic algorithm remains the same; the most significant speedups
come from the following three changes:
(1) normalize by shifting instead of multiplying and dividing
(2) the old algorithm usually did an unnecessary extra iteration of
the outer loop; remove this. As a special case, this means that
long divisions with a single-digit result run twice as fast as
before.
(3) make inner loop much tighter.
Various benchmarks show speedups of between 50% and 150% for long
integer divisions and modulo operations.
........
- new configure option --enable-big-digits
- new structseq sys.int_info giving information about the internal format
By default, 30-bit digits are enabled on 64-bit machines but
disabled on 32-bit machines.

Issue #5260: Various portability and standards compliance fixes, optimizations
and cleanups in Objects/longobject.c. The most significant change is that
longs now use less memory: average savings are 2 bytes per long on 32-bit
systems and 6 bytes per long on 64-bit systems. (This memory saving already
exists in py3k.)

No need for carry to be type twodigits in _PyLong_AsByteArray; digit is large enough.
This change should silence a compiler warning on Windows.

Issue #4393: fix 3 classes of potential portability problems in longobject.c:
- fix some places where counters into ob_digit were declared as
int instead of Py_ssize_t
- add (twodigit) casts where necessary
- fix code in _PyLong_AsByteArray that uses << on negative values
........
- fast path wasn't being properly taken for negative ints;
thanks Victor Stinner for pointing this out.
- use Py_SAFE_DOWNCAST instead of direct casting to digit
(it's safer, especially if we ever consider moving to 30-bit
digits)
- cleaner way to write negation
