Get snapping to character grid working again, avoid crashes when attempting
to resize below 1x1 character cell, only redraw when size actually changes.
Also, rename window_get_child_rectangle() to window_get_child_allocation().
Implement the concealed attribute, and 16-colour attributes. Fix a bug in
256-colour attributes that prevented them from working in elinks.

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

the cairo toy font API doesn't do font substitution.
