8a838b0372 Add support for overlay popup boxes to show text or output temporarily
above the normal layout. These work similarly to menus and are created
with the display-popup command.

4ff7bc3eb3 When system calls indicate an error they return -1, not some arbitrary
value < 0.  errno is only updated in this case.  Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

not exit until jobs started from run-shell/if-shell have finished (add a
job flags member and a flag to indicate other jobs). GitHub issue 1245.

932f6cfbfc Because ignore SIGCHLD early, letting signal_del restore it doesn't work
correctly, so set it explicitly back to default (and the others for good
measure).

51112221ee Block signals between forking and clearing signal handlers (or calling
event_reinit) - if the child gets a signal and fires the libevent signal
handler during this period it could write a signal into the parent's
signal pipe. GitHub issue 1001 from Aaron van Geffen.

0b44ad99b5 If a #() command doesn't exit, use its most recent line of output (it
must be a full line). Don't let it redraw the status line more than once
a second.

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).

021cdbe1c0 Use an explicit job state instead of avoid closing our side of the
socketpair and setting it to -1 to mark when the other side is
closed. This avoids closing it while the libevent bufferevent still has
it (it could try to add it to the polled set which some mechanisms don't
like). Fixes part a problem reported by Bruno Sutic.

db7a89b1ee Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.

Status jobs now managed with two trees of output (new and old), rather
than storing the output in the jobs themselves. When the status line is
processed any jobs which don't appear in the new tree are started and
the output from the old tree displayed. When a job finishes it updates
the new tree with its output and that is used for any subsequent
redraws. When the status interval expires, the new tree is moved to the
old so that all jobs are run again.

This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands
of identical persistent jobs and high memory use (this can still be
achieved by adding "sleep 30" but that is much less likely to happen by
accident).

e3be9b1951 Do not call event_del() for signals after fork(), just use sigaction()
directly instead - calling libevent functions after fork() w/o
event_reinit() is a bad idea, even if in this case it was harmless.

abf3a5d50e Initial changes to move tmux to libevent.
This moves the client-side loops are pretty much fully over to event-based only
(tmux.c and client.c) but server-side (server.c and friends) treats libevent as
a sort of clever poll, waking up after every event to run various things.

Moving the server stuff over to bufferevents and timers and so on will come
later.

2f813ef75d Add a flag for jobs that shouldn't be freed after they've died and use it for
status jobs, then only kill those jobs when status-left, status-right or
set-titles-string is changed.
