- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

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.
