umask 177 instead of 117 because it may not be in a safe directory like
the default directory in /tmp. The user can chmod it more open after it
is created if they want.

Rewrite the code for reading and writing files. Now, if the client is
...
not attached, the server process asks it to open the file, similar to
how works for stdin, stdout, stderr. This makes special files like
/dev/fd/X work (used by some shells). stdin, stdout and stderr and
control mode are now just special cases of the same mechanism. This will
also make it easier to use for other commands that read files such as
source-file.

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).
