Regression introduced by the implementation of the PEP 446 (non-inheritable
file descriptors by default).

master_fd must be set non-inheritable after the creation of the slave_fd,
otherwise grantpt(master_fd) fails with EPERM (errno 13).

name in their docstring. Patch written by Vajrasky Kok.

Also, replace unnessary uses of the #if preprocessor directive.

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.
