There aren't many client message types or code to handle them so get rid of the

lookup table and use a switch, merge the tiny handler functions into it, and
move the whole lot to client.c.

Also change client_msg_dispatch to consume as many messages as possible and
move the call to it to the right place so it checks for signals afterwards.

Prompted by suggestions from eric@.
