Ed Schouten eba77f5c40 Commit all local modifications I have to libteken:
- Make xterm/cons25 support runtime configurable. This allows me to
  share libteken between syscons and my new vt driver.
- Add a fix to print blanks after printing a double width character to
  prevent rendering artifacts.
- Add some more utility functions that I use in the vt driver.
