Issue #17768 : Support newline fill character in decimal.py and NUL fill

character in _decimal.c.

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.

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.

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).

mpd_qpowmod(): calculate result with zero-exponent for compatibility with

decimal.py. The hack to remove the ideal exponent is no longer required.

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!).

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.

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.

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.

Allow printing a leading '-' and the maximum number of exponent digits

rather than raising RuntimeError (allocated space is sufficient for the
additional character).

Raise InvalidOperation if exponents of zeros are clamped during exact
...
conversion in the Decimal constructor. Exact here refers to the
representation and not to the value (clamping does not change the value).

Raise MemoryError instead of InvalidOperation/MallocError for compatibility
...
with decimal.py. The standard specifies InsufficientStorage (MallocError) as
a sub-condition of InvalidOperation. This allows a calculation to continue
with NaN results when allocation fails.
