Split the server code handling clients, jobs and windows off into separate
...
files from server.c (merging server-msg.c into the client file) and rather than
iterating over each set after poll(), allow a callback to be specified when the
fd is added and just walk once over the returned pollfds calling each callback
where needed.
More to come, getting this in so it is tested.

Some terminals don't correctly clear their let's-wrap flag after changing the
...
scroll region (which moves the cursor to 0,0). This means that if the cursor
was at the edge of the screen, any further output after scroll region change
incorrectly causes a line wrap. Add a workaround to move the cursor to position
0 if it is at the screen edge before changing scroll region.

Try to reduce the UTF-8 mess.
...
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.

UTF-8 combined character fixes.
...
Thai can have treble combinations (1 x width=1 then 2 x width=0) so bump the
UTF-8 cell data size to 9 and alter the code to allow this.
Also break off the combining code into a separate function, handle any further
combining beyond the buffer size by replacing the character with _s, and when
redrawing the UTF-8 character don't assume the first part has just been
printed, redraw the entire line.
