* Add GNUInstallDirs for standard installation directories
Distributions are given standard variables for already existing hooks.
Multiarch libdirs is taken care of automagically.
Raises minimum cmake version by a little.
* Handle CMAKE_INSTALL_xxx being absolute paths for .pc file generation
In some cases the CMAKE_INSTAL_{BIN,MAN,DOC,LIB,INCLUDE}DIR variables
may turn out to be absolute paths in which case prepending ${prefix} in
the pkg-config .pc files will result in incorrect values.
For .pc file generation, figure out if these variables are absolute and
omit the prefix in the configured file when so.

r2077 did expose too much of the detail implementation of OpenJPEG. Rework dependencies in between JPIP file level details and JPIP client/server arch.
Move JPIP file level functionalities back into OpenJP2 as was the case in openjpeg 1.5.x. Use new cio func.
