Change from a per-session stack of buffers to one global stack which is
much more convenient and also simplifies lot of code. This renders
copy-buffer useless and makes buffer-limit now a server option.

Unify the way sessions are used by callbacks - store the address and use
the reference count, then check it is still on the global sessions list
in the callback.

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.

Send all three of stdin, stdout, stderr from the client to the server, so that
commands can directly make use of them. This means that load-buffer and
save-buffer can have "-" as the file to read from stdin or write to stdout.

This is a protocol version bump so the tmux server will need to be restarted
after upgrade (or an older client used).

In load-buffer, read until EOF rather than using stat() and reading a fixed
size. Allows use of FIFOs and whatnot. From Tiago Cunha, idea from Fulvio
Ciriaco.

Change paranoia check to check for <= 0 and to avoid warning.

Tidy up various bits of the paste code, make the data buffer char * and add
comments.

Get rid of the ugly CMD_CHFLAG macro and use a const string (eg "dDU") in the
command entry structs and a couple of functions to check/set the flags.

Call fstat() after fopen() rather than stat() before.

Give each paste buffer a size member instead of requiring them to be
zero-terminated.

Don't babysit people and let them try to load /dev/zero or (more useful)
/dev/null if they want.

Make all messages sent between the client and server fixed size.

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.

Having fixed flags for single-character getopt options is a bit hard to
maintain and is only going to get worse as more are used. So instead, add a new
uint64_t member to cmd_entry which is a bitmask of upper and lowercase options
accepted by the command.

This means new single character options can be used without the need to add it
explicitly to the list.
