6edda14b29 Issue #17768: Support newline fill character in decimal.py and NUL fill
character in _decimal.c.

eb8c451bd2 Since the return type of format() is not a Decimal, raise ValueError instead of
InvalidOperation if the format specification (width, prec) exceeds the internal
limits of libmpdec.

040e311826 Issue #15783: Except for the number methods, the C version of decimal now
supports all None default values present in decimal.py. These values were
largely undocumented.

dbcf103be0 Issue #15882: Change _decimal to accept any coefficient tuple when
constructing infinities. This is done for backwards compatibility
with decimal.py: Infinity coefficients are undefined in _decimal
(in accordance with the specification).

f21587e3a8 mpd_qpowmod(): calculate result with zero-exponent for compatibility with
decimal.py. The hack to remove the ideal exponent is no longer required.

ad5b43995e In the 32-bit build, dec_hash() raised InvalidOperation if the operand
had a coefficient with MAX_PREC=425000000 digits and a negative exponent.
Increasing the context limits above the official values fixes the issue
and is safe (in this case!).

b9e36b97f2 Add unused parameter to a couple of METH_NOARGS functions. The previous
form is used in many places in the source tree, but was found to be incorrect
in a recent tracker discussion.

c35a8e5c98 Proactive reliability fix for broken FPUs: The base conversion functions
use log10() to calculate the size of the output array. The current code
has been tested on x86/amd64 (and to a lesser extent on qemu-mips qemu-sparc)
and produces sufficiently large values for all inputs tested so far (coefficient
sizes of 10**18 - 1 are hard to test exhaustively).

The new code does not rely on the correctness of log10() and resizes
the output arrays if the allocated space is insufficient.

78f075636c Speed up _decimal by another 10-15% by caching the thread local context
that was last accessed. In the pi benchmark (64-bit platform, prec=9),
_decimal is now only 1.5x slower than float.
