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.

293e331d69 Add functions to allocate and free command contexts rather than doing it all on
the stack.

c8849ac990 Sync OpenBSD patchset 1153:
Add a queue of notifys and a way to turn them off and on (we do not want
notifys to happen during some commands). Based on code from George
Nachman.

Make command exec functions return an enum rather than -1/0/1 values and
add a new value to mean "leave client running but don't attach" to fix
problems with using some commands in a command sequence. Most of the
work by Thomas Adam, problem reported by "jspenguin" on SF bug 3535531.

0159c74a32 Sync OpenBSD patchset 1138:
Add a skeleton mode to tmux (called "control mode") that let's tmux
commands be sent and output received on stdout. This can be used to
integrate with other terminal emulators and should allow some other
things to be made simpler later. More to come so doesn't do much yet and
deliberately not documented.

|Author: nicm
|Branch: HEAD
|Tag: (none)
|Log:
|We now send argv to the server after parsing it in the client to get the
|command, so the client should not modify it. Instead, take a copy. Fixes
|parsing command lists, reported by mcbride@.

03c1c1cd9f Sync OpenBSD patchset 727:
Setting the cmdlist pointer in the bind-key to NULL to prevent it being freed
after the command is executing is bogus because it may still be needed if the
same command is going to be executed again (for example if you "bind-key a
bind-key b ..."). Making a copy is hard, so instead add a reference count to
the cmd_list.

While here, also print bind-key -n and the rest of the flags properly.

Fixes problem reported by mcbride@.

Don't stop parsing command sequences when a command requests the client to
stick around (attach-session/new-session).

d637cb33da Sync OpenBSD patchset 181:
Make all messages sent between the client and server fixed size.

This is the first of two changes to make the protocol more resilient and less
sensitive to other changes in the code, particularly with commands. The client
now packs argv into a buffer and sends it to the server for parsing, rather
than doing it itself and sending the parsed command data.

As a side-effect this also removes a lot of now-unused command marshalling
code.

Mixing a server without this change and a client with or vice versa will cause
tmux to hang or crash, please ensure that tmux is entirely killed before
upgrading.
