The evbuffer API is very similar to the existing tmux buffer API so this was
remarkably painless. Not many possible ways to do it, I suppose.

Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.
Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.

wrapped, move the cursor back up to the end of the previous line.
Another one of the forgotten persons requested this quite a while ago (I need
to start noting names on todo items...) when it was quite hard to
implement. Now it is easy and I don't see it can do any harm, so hey presto...

there is unconsumed data, save the previous size and use it instead. This means
that activity monitoring should work in this (unlikely) event.
Also remove a debugging statement that no longer seems necessary.

wrapped at the screen edge from those terminated by a newline. Then use this
when copying to combine wrapped lines together into one.

colours and attributes. Found thanks to a report from Taylor Venable.
While here also nuke a couple of extra blank lines.

tweak a redundant expression in window_pane_set_mode.

screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.

vttest test happy.

do cancel the sequence, and tweak to make the code more clear.

in the same state.

control character VT (vertical tab, \013), which is treated as LF like
VT102. Makes another vttest happy.

first cursor test in vttest (in ports) to pass; it still shops a few more
problems though.

machine but top-bit-set nonprintables could cause trouble, and they are neater
like this anyway.
Suggested by deraadt a few days ago.

terminal to be switched between several different windows and programs
displayed on one terminal be detached from one terminal and moved to another.
