List NBSP under adjustable spaces in CharUtilities.

Generate space elements in the area tree from spaces in fo:character.
Clearly mark test cases which test for NBSP.
Document failure to generate adjustable spaces from fo:character in a disabled test case.
Adjust checks to the fact the fo:character can now also generate spaces.
Enable block_white-space-collapse_2.xml again
