Nils Philippsen b2c6bd7614 Backport lcms 2.x support from master, making it optional. 
In order to retain support for lcms 1.x, this merges the lcms2-specific
code as a configurable alternative.

The user can specify which version to use by specifying
"--with-lcms=lcms1" or "--with-lcms=lcms2" when running configure. If no
version is specified explicitly, version 1.x will be preferred if both
versions are available. This ensures that GIMP is built with the same
lcms version as an older version, if the same configure switches are
used and the same libraries are available.

This builds on the following commits from the master branch:

    commit c59ab4d817
    Author:     Massimo Valentini <mvalentini@src.gnome.org>

    AuthorDate: Mon Sep 3 20:03:53 2012 +0200

        Bug 675558 - switch from lcms-1 to lcms-2

        Applied modified patch from Hartmut Kuhse which ports to lcms-2.
