Add a command queue to standardize and simplify commands that call other commands and allow a command to block execution of subsequent commands. This allows run-shell and if-shell to be synchronous which has been much requested. Each client has a default command queue and commands are consumed one at a time from it. A command may suspend execution from the queue by returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() - for example run-shell does this from the callback that is fired after the job is freed. When the command queue becomes empty, command clients are automatically exited (unless attaching). A callback is also fired - this is used for nested commands in, for example, if-shell which can block execution of the client's cmdq until a new cmdq becomes empty. Also merge all the old error/info/print functions together and lose the old curclient/cmdclient distinction - a cmdq is bound to one client (or none if in the configuration file), this is a command client if c->session is NULL otherwise an attached client.

Sync OpenBSD patchset 829: 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.
