Add https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html
to auto-detect compiler flags, linker flags and libraries to compile
OpenSSL extensions. The M4 macro uses pkg-config and falls back to
manual detection.
Add autoconf magic to detect usable X509_VERIFY_PARAM_set1_host()
and related functions.
Refactor setup.py to use new config vars to compile _ssl and _hashlib
modules.

This module has never been enabled by default, never worked correctly
on x86-64, and caused ABI problems that caused C extension
compatibility. See bpo-29137 for details/discussion.
Include sys/sysmacros.h for major(), minor(), and makedev(). GNU C libray
plans to remove the functions from sys/types.h.
