Document that @property can incorporate a docstring from the getter method.  Improve readabilty with additional whitespace.

I also removed some bare excepts from the tests.

Changed deprecation message in the fileinput module.

This doesn't make any functional changes to the exisiting implementation.  The
conversion did help however uncover documentation bugs. The best thing about
this conversion is less C code to maintain by hand.

   _decimal:

      o Make all "mpd_t to C integer" conversion functions available in both the
        64-bit and the 32-bit versions.

      o Make all mixed mpd_t/C integer arithmetic functions available in the
        32-bit version.

      o Better handling of __STDC_LIMIT_MACROS for C++ users.

      o Add struct tags (at the request of C++ users).

2) Check for libmpdec.so.2 if --with-system-libmpdec is used.

the length doesn't fit in an DWORD

Explain that unhandled error case is very unlikely

for new allocations, but not when a memory block was already resized

Apparently, the number of objects with docstrings in builtins varies
with --with-pydebug (non-debug has one fewer).

Also, skip the new tests entirely if built --without-doc-strings.

written in C.

As a part of this, a few doctests have been added to the builtins module
(on hex(), oct(), and bin()), a doctest has been fixed (hopefully on all
platforms) on float, and test_builtins now runs doctests in builtins.
