c5239c5984 Add resize-pane -Z to temporary zoom the active pane to occupy the full window
or unzoom (restored to the normal layout) if it already zoomed, bound to C-b z
by default. The pane is unzoomed on pretty much any excuse whatsoever.

We considered making this a new layout but the requirements are quite different
from layouts so decided it is better as a special case. Each current layout
cell is saved, a temporary one-cell layout generated and all except the active
pane set to NULL.

Prompted by suggestions and scripts from several. Thanks to Aaron Jensen and
Thiago Padilha for testing an earlier version.

3964309c67 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.

f536dc47c4 If stdin in the client is enable immediately, tmux will eat anything
sent to stdin before it is needed, which can be inconvenient (eg pasting
commands). Instead, start with stdin disabled and reuse MSG_STDIN from
server->client to mean that stdin should be enabled. Based on a diff
from Chris Johnsen.

Instead of passing stdin/stdout/stderr file descriptors over imsg and
handling them in the server, handle them in the client and pass buffers

The tty fd is still passed to the server as before.

This bumps the tmux protocol version so new clients and old servers are
incompatible.

d7bae0edce Sync OpenBSD patchset 741:
When changing so that the client passes its stdout and stderr as well as
stdin up to the server, I forgot one essential point - the tmux server
could now be both the producer and consumer. This happens when tmux is
run inside tmux, as well as when piping tmux commands together.

So, using stdio(3) was a bad idea - if sufficient data was written, this
could block in write(2). When that happened and the server was both
producer and consumer, it deadlocks.

Change to use libevent bufferevents for the client stdin, stdout and
stderr instead. This is trivial enough for output but requires a
callback mechanism to trigger when stdin is finished.

This relies on the underlying polling mechanism for libevent to work
with whatever devices to which the user could redirect stdin, stdout or
stderr, hence the change to use poll(2) over kqueue(2) for tmux.

b01dcd7971 Remove the internal tmux locking and instead detach each client and run the
command specified by a new option "lock-command" (by default "lock -np") in
each client.

This means each terminal has to be unlocked individually but simplifies the
code and allows the system password to be used to unlock.

Note that the set-password command is gone, so it will need to be removed from
configuration files, and the -U command line flag has been removed.

This is the third protocol version change so again it is best to stop the tmux
server before upgrading.
