Completely replace lcms1 by lcms2 in Ubuntu

[szukw000 at arcor.de]

I have sent a patch for libmng-1.1.10 to glennrp of the
png-mng-implement list because I need lcms2 support in
libmng.

This patch contains changes to use liblcms2, optionally
liblmcs.

Additionally the file 'makefiles/configure.in' has been
changed.

I have added 'CMakeLists.txt' files to allow usage of
CMAKE.

I have tested the changed library on linux-3.x (64-bit),
Win7 (64-bit) and PowerMac G5 (WORDS_BIGENDIAN).

Glenn has told me that he wants to make some more tests.
