objects. (1) The comparison could incorrectly return True in some cases
(2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
(2) The comparison raised an OverflowError for large integers, leading
to unpredictable exceptions when combining integers and complex objects
in sets or dicts.

Include ieeefp.h (when available) in pyport.h instead of individually in
Objects/floatobject.c and Objects/complexobject.c. This should silence
compiler warnings about implicit declaration of the 'finite' function
on Solaris.

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.
nb_long: remove last remaining use of nb_long
(in the struct module) from the core, set nb_long slots on all builtin
and extension types to 0, and remove uses of __long__ in test_complex
and test_binop.
