Drop compatibility with CMake < 2.4 

Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so.  In the error suggest using a CMake 2.8.x release.

Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4.  They are not supported by CMake >= 3.0.

Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.

CMAKE_BACKWARDS_COMPATIBILITY
-----------------------------
Version of cmake required to build project
From the point of view of backwards compatibility, this specifies what
version of CMake should be supported. By default this value is the
version number of CMake that you are running. You can set this to an
older version of CMake to support deprecated commands of CMake in
projects that were written to use older versions of CMake. This can
be set by the user or set at the beginning of a CMakeLists file.
Deprecated. See CMake Policy :policy:`CMP0001` documentation.
