2) Assert that the source operand is not special. Prevent resulting assert
failure (harmless) by initializing flags before calling mpd_qshiftr_inplace.
3) Save a couple of instructions (mpd_zerocoeff already sets digits and len).
Reorder initialization to match the order in the mpd_t struct.

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).

Use abort() rather than exit() to appease tools like rpmlint. abort() is used
...
in libmpdec to prevent undefined behavior if an invalid context is used. This
cannot occur for the _decimal module since user input for the context is
validated.

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.

Issue #7652 : Integrate the decimal floating point libmpdec library to speed

up the decimal module. Performance gains of the new C implementation are
between 12x and 80x, depending on the application.
