85338bb75f Add support for custom command aliases, this is an array option which
contains items of the form "alias=command". This is consulted when an
unknown command is parsed.

98e7fbb2ac Open /dev/ptm before pledge() and save it to be used for PTMGET later
(this means inlining forkpty()).

73e30cbda8 Actually show something (even if it not that helpful) if the server
fails to start (for example if it can't create the socket), rather than

01defc9f49 Because pledge(2) does not allow us to pass directory file descriptors
around, we can't use file descriptors for the working directory because
we will be unable to pass it to a privileged process to tell it where to
read or write files or spawn children. So move tmux back to using
strings for the current working directory. We try to check it exists
with access() when it is set but ultimately fall back to ~ if it fails
at time of use (or / if that fails too).

6b2129696f Move the nested check from client to server and compare the client tty
name to all the pane pty names instead of comparing socket paths. This

8e4ae12b4d lockf is entirely useless and it was a mistake to change to it, go back
to using flock which actually works sensibly. Also always retry the lock
to fix a potential race, and add some extra logging.

c1ccefc62d We accidentally haven't been using $TMUX to work out the session for a
while and in fact it is less useful that using the client ttyname. So
don't bother and don't pass it from the client. If we need it in future
it is in c->environ.

282c5f9644 Alter how tmux handles the working directory to internally use file
descriptors rather than strings.

- Each session still has a current working directory.

- New sessions still get their working directory from the client that
  created them or its attached session if any.

- New windows are created by default in the session working directory.

- The -c flag to new, neww, splitw allows the working directory to be
  overridden.

- The -c flag to attach let's the session working directory be changed.

- The default-path option has been removed.

To get the equivalent to default-path '.', do:

        bind c neww -c $PWD

To get the equivalent of default-path '~', do:

        bind c neww -c ~

This also changes the client identify protocol to be a set of messages rather
than one as well as some other changes that should make it easier to make
backwards-compatible protocol changes in future.
