4f96f5ffc6 Issue #8567: Fix incorrect precedence of signals in Decimal module. 
When a Decimal operation raises multiple signals and more than one of
those signals is trapped, the specification determines the order in
which the signals should be handled.  In many cases this order wasn't
being followed, leading to the wrong Python exception being raised.
This commit fixes those cases, and adds extra tests.  The tests are
only enabled when EXTENDEDERRORTESTS is True, since they involve
rerunning each Decimal testcase several times.

f3eeca16cb Issue #7279: Make Decimal('nan') hashable. Decimal('snan') remains unhashable. 
Also rewrite the Decimal __hash__ method so that it doesn't rely on
float('inf') being valid: float('inf') could raise an exception on
platforms not using IEEE 754 arithmetic.

99d8096c17 Issue #2531: Make float-to-decimal comparisons return correct results. 
Float to decimal comparison operations now return a result based on
the numeric values of the operands.  Decimal.__hash__ has also been
fixed so that Decimal and float values that compare equal have equal
hash value.

DIGIT ONE}') are *not* accepted in a numeric string.

72bc54faed Major change in the internal structure of the Decimal 
number: now it does not store the mantissa as a tuple
of numbers, but as a string.

This avoids a lot of conversions, and achieves a
speedup of 40%. The API remains intact.

Thanks Mark Dickinson.

9b5e23148b The constructor from tuple was way too permissive: it allowed bad 
coefficient numbers, floats in the sign, and other details that
generated directly the wrong number in the best case, or triggered
misfunctionality in the alorithms.

Test cases added for these issues. Thanks Mark Dickinson.

1a191df14d Made the various is_* operations return booleans. This was discussed 
with Cawlishaw by mail, and he basically confirmed that to these is_*
operations, there's no need to return Decimal(0) and Decimal(1) if
the language supports the False and True booleans.

Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).

Thanks Mark Dickinson

353750c405 Merged the decimal-branch (revisions 54886 to 58140). Decimal is now 
fully updated to the latests Decimal Specification (v1.66) and the
latests test cases (v2.56).

Thanks to Mark Dickinson for all his help during this process.
