Backout my last changes. ISO-8859-15 does not specify ACS graphics.
Requested by: ache

Add curses ACS line graphics support for iso15 fonts
Now ncurses-based programs such as sysinstall and mc will display the
correct font for graphical lines instead of "-" and "+" characters.

Correct two special characters for cons25l1 in termcap: use real
arrows instead of ">>" and "<<".
Add a lot of additional symbols for line drawing which are taken from
the CP437 font.
Almost all of the ACS symbols are now implemented.

Standards conformance cleanup

New ISO-8859-15 thin font. It includes some missing characters from 8859-1
(like OE & oe diphthong) and the Euro character. It also includes the VTxx
semi-graphic characters.
