reorganize the defines slightly to make adding support easier.

  copysign shouldn't be declared as static in pymath.c
........

a fallback function if round doesn't exist.

string <-> float conversion routines to make round(x, n) correctly
rounded for floats x, so that it always agrees with format(x, '.<n>f').

Also fix some other round nuisances, like round(123.456, 1-2**31) giving
an integer rather than a float.

we can't figure out how to get and set the x87 control word.

Make it so.

separate FormatTestCase classes have been combined,
and test_short_repr has been moved from FormatTestCase
to the existing ReprTestCase.

Fix a bug in the memory management in dtoa.c.

digits of precision for floats.

Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
    with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
    for floats.
