Too many build tool chains do not properly support it, including building
and linking an executable fine that simply segfaults when you try to run
it (such as debian jessie 8.5's gcc 4.9).  On others where it does appear
to build (ubuntu 16.04's gcc 5.4) there are still test_distutils and test_gdb
failures to deal with.

We're not going to spend time attempting to maintain a complicated white list
of what does and doesn't work in our configure.ac file.

The function internal_setblocking() of the socket module did not check
the return values of ioctl() and fnctl().

PyModule_GetDef() can return NULL. Let's check the return value properly
like in the other five cases.

Also make it clear on the contents page what chapters are about the
legacy API.

The _locale module was using old-style APIs to set numeric module
constants from macros. The new way requires less code and properly
checks for NULL.
