Fix several bugs in the previous patches. Fix inverse inverse video
with bold attribute, incorrect duplication of attributes when scrolling
up, underline aliasing, bottom scroll margin adjustment when resizing,
and unnecessary sleep when sending terminal reports. Change TERM
environment variable to xterm-256color to better reflect terminal
capabilities (although it still doesn't emulate all of xterm).

Includes the 3 vt100 character sets. Some of the graphic symbols don't
display because they are not included in the default font. Apparantly
the cairo toy font API doesn't do font substitution.

The new map_toplevel() request no longer specifies a position and takes
the size from the attached buffer. The attach request now takes a
position relative to the top-left corner of the old buffer to let
clients specify the relative position of the new buffer.
