Clean up and simplify tmux command argument parsing. Originally, tmux commands were parsed in the client process into a struct with the command data which was then serialised and sent to the server to be executed. The parsing was later moved into the server (an argv was sent from the client), but the parse step and intermediate struct was kept. This change removes that struct and the separate parse step. Argument parsing and printing is now common to all commands (in arguments.c) with each command left with just an optional check function (to validate the arguments at parse time), the exec function and a function to set up any key bindings (renamed from the old init function). This is overall more simple and consistent. There should be no changes to any commands behaviour or syntax although as this touches every command please watch for any unexpected changes.

Memory could be leaked if a second prompt or message appeared while another was still present, so add a separate prompt free callback and make the _clear function responsible for calling it if necessary (rather than the individual prompt callbacks). Also make both messages and prompts clear any existing when a new is set. In addition, the screen could be modified while the prompt is there, restore the redraw-entire-screen behaviour on prompt clear; add a comment as a reminder.
