c930fd5ff6 Remember the last active pane in the top-bottom or left-right cell so
that it can be restored when moving back to that cell with selectp
-L/-R/etc. From Suraj N Kurapati.

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.

90ae7682ed Clear window->flags when clearing winlinks
When clearing WINLINK_ALERTFLAGS for all sessions, we must also, for
that window, clear the window->flags as well, otherwise sessions may
well still see flags for winlinks long since cleared.

This therefore introduces WINDOW_ALERTFLAGS to help with this.

c71844de63 Add resize-pane -Z to temporary zoom the active pane to occupy the full
window or unzoom (restored to the normal layout) if it already zoomed,
bound to C-b z by default. The pane is unzoomed on pretty much any
excuse whatsoever.

We considered making this a new layout but the requirements are quite
different from layouts so decided it is better as a special case. Each
current layout cell is saved, a temporary one-cell layout generated and
all except the active pane set to NULL.

Prompted by suggestions and scripts from several. Thanks to Aaron Jensen
and Thiago Padilha for testing an earlier version.

Nicholas Marriott
f59971276a Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 50/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.

This makes tmux much more responsive under very fast output (for example
yes(1) or accidentally cat'ing a large file) but may not be perfect on
all terminals and connections - feedback very welcome, particularly
where this change has a negative rather than positive effect (making it
off by default is a possibility).

After much experimentation based originally on a request Robin Lee
Powell (which ended with a completely different solution), this idea
from discussion with Ailin Nemui.

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.

7d5e494716 When using tmux as a login shell, there is currently no way to specify a shell
to be used as a login shell inside tmux, so add a default-shell session option.
This sets the shell invoked as a login shell when the default-command option is
empty.

The default option value is whichever of $SHELL, getpwuid(getuid())'s pw_shell
or /bin/sh is valid first.

than a window option.

4310282a4c Have the client pass its stdin fd to the server when identifying itself and
have the server use that rather than reopening the tty. If the fd isn't given,

try not execute itself.

6491274f60 Infrastructure and commands to manage the environment for processes started
within tmux.

There is a global environment, copied from the external environment when the
server is started and each sesssion has an (initially empty) session
environment which overrides it.

New commands set-environment and show-environment manipulate or display the
environments.

A new session option, update-environment, is a space-separated list of
variables which are updated from the external environment into the session
environment every time a new session is created - the default is DISPLAY.

6036bdd06c Improved layout code.
Each window now has a tree of layout cells associated with it. In this tree,
each node is either a horizontal or vertical cell containing a list of other
cells running from left-to-right or top-to-bottom, or a leaf cell which is
associated with a pane.

The major functional changes are:

- panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and
  vertically (splitw -v, C-b ");
- panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D,
  bound to C-b left/right/up/down and C-b M-left/right/up/down);
- layouts are now applied and then may be modified by resizing or splitting
  panes, rather than being fixed and reapplied when the window is resized or
  panes are added;
- manual-vertical layout is no longer necessary, and active-only layout is gone
  (but may return in future);
- the main-pane layouts now reduce the size of the main pane to fit all panes
  if possible.

Thanks to all who tested.

9601b72e4c The man page says that kill-window removes the window entirely, unlinking it
from any sessions. In fact the implementation only affected the current
session, making it the same as unlink-window but destroying the window if it
was linked into only one session (unlinkw gives an error). Change the behaviour
to match what it documented and was originally intended.

084d07f4eb Just appending -l to $SHELL to create a login shell is wrong: -l is not POSIX,
and some people may use shells which do not support it. Instead, make an empty

which is the method used by login(1).

Also fix the automatic-rename code to handle this correctly and to strip a
leading - if present.

7e796dea03 Change find-window and monitor-content to use fnmatch(3). For convenience and
