Subject: Fix charset detection code in configure. Now we are: 1. Try to find
 correct name for default character sets for the platform 2. Use
 DEFAULT_{DOS|DISPLAY|UNIX}_CHARSET defines set during configure phase as
 defaults

This should fix CP850 problem on Solaris (at least) because it actually has IBM850 which
is the same but under different name
(This used to be commit 836b9fffa0eadc818019ba36ed764e97d4f9a801)
