export: Factor out CMake-specific export generation (2/2)
 
In order to support generation of Common Package Specifications, the
mechanisms CMake uses to export package information need to be made more
abstract. The prior commits began this refactoring; this continues by
(actually) restructuring the classes used to generate the actual export files.
To minimize churn, this introduces virtual base classes and
diamond inheritance in order to separate logic which is format-agnostic
but depends on the export mode (build-tree versus install-tree) from
logic which is format-specific but mode-agnostic.

This could probably be refactored further to use helper classes instead,
and a future commit may do that, however an initial attempt to do that
was proving even more invasive, such that this approach was deemed more
manageable.

While we're at it, add 'const' in more places where possible.

Find PHP4

This module finds if PHP4 is installed and determines where the
include files and libraries are.  It also determines what the name of
the library is.  This code sets the following variables:

::

  PHP4_INCLUDE_PATH       = path to where php.h can be found
  PHP4_EXECUTABLE         = full path to the php4 binary
#]=======================================================================]
