Style/consistency/nano-optimization nit: replace occurrences of
(high_bits << PyLong_SHIFT) + low_bits with
(high_bits << PyLong_SHIFT) | low_bits
in Objects/longobject.c. Motivation:
- shouldn't unnecessarily mix bit ops with arithmetic ops (style)
- this pattern should be spelt the same way thoughout (consistency)
- it's very very very slightly faster: no need to worry about
carries to the high digit (nano-optimization).

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.)

- 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

Adds a sanity check to avoid a *very rare* infinite loop due to a corrupt tls
key list data structure in the thread startup path.
This change is a companion to r60148 which already successfully dealt with a
similar issue on thread shutdown.
In particular this loop has been observed happening from this call path:
#0 in find_key ()
#1 in PyThread_set_key_value ()
#2 in _PyGILState_NoteThreadState ()
#3 in PyThreadState_New ()
#4 in t_bootstrap ()
#5 in pthread_start_thread ()
I don't know how this happens but it does, *very* rarely. On more than
one hardware platform. I have not been able to reproduce it manually.
(A flaky mutex implementation on the system in question is one hypothesis).
As with r60148, the spinning we managed to observe in the wild was due to a
single list element pointing back upon itself.
