Make sure servers get killed on user-initiated quit. If we just HUP the shell then the server won't notice until it becomes attached as an orphan on the next launch. Issue 6369

Fix a bug where iTerm2 would hang when a fd server exited before we attached to it (which could happen if the command failed to exec or exited right away). Also fix a leak of file descriptors (serverConnectionFd).

Add an off-by-default advanced pref to redraw the screen after Clear Buffer is selected. It's off by default because of the possible privacy implications (you might hit cmd-k quickly when your boss is walking by). Also refactor how size is used by PTYTask, VT100Screen, and PTYSession to be a VT100GridSize instead of two variables. Issue 4494.

Use DEPRECATED_ATTRIBUTE to mark functions deprecated in the comments.

Not every class was looked over, though.
Remove redundant declarations of dealloc in interface blocks.
Mark constructors of classes with instancetype instead of id.

Give the user the option to append or replace log files. Remember the last used directory for the logfile save panel

Establish socket connection between client and server before fork()ing to remove sleep-retry loop after fork(). Nuke the whole sleep-retry loop.

Pass around an iTermFileDescriptorServerConnection instead of a triple of fd and two pids.

Kill the server when there’s a broken pipe.

Don’t leak unix-domain socket file descriptors. Close them when the server dies.

Session restoration improvments: Improve Sparkle support for session restoration. Don't prompt for a sparkle restart if sessions will be restored. Don't terminate jobs on shutdown for a sparkle restart. Put newlines around Session Restored message. Exponentially increase delay when first attaching, starting at 1ms. Handle failures to attach to new servers.  Fix bug where working directory was fetched from the server PID, which isn't so good when there isn't one.

Move source into sources/ directory. Delete a few unused images in the process and fix a reference to an Aqua image in FindView

Fix a race condition where broken pipes might cut off the end of output. Rewrite how commands are parsed.

Make debug logging thread-safe. Add appendBytes:length:excludingCharacter: to NSMutableData. Do low-level tmux parsing in new VT100TmuxParser class to simplify PTYSession’s threadedReadTask: method. Fix race condition where threadedReadTask: could run after dealloc was begun. Remove the not-so-useful kTmuxGatewayCommandHasEndGuardBug flag. Fix analyzer issues and some leaks.

Add optimizations for ascii strings, plus various other smaller optimizations. Fix warnings. Fix a few bugs. Make thread save data when the terminal needs raw data for clipboard copying instead of passing possibly dangling pointers in token.position. Update architectures for test target.

Create iTermColorMap to reduce duplicate code between PTYSession and PTYTextView. Also do a general cleanup, fix broken tests.

Fix bug where, when a new session is created with a custom starting directory, a login shell was not used. The fix is to run login -fpl $USER iTerm --launch_shell. We modify main() to see the --login-shell flag and exec the shell adding a - before its argv0.

Fix bug where the 'home dir' setting for an advanced directory option never ran login, but your shell instead.

Fix crash on closing a session where a task is freed before routing coprocess I/O. Retain the task in the I/O loop and make sure it hasn't died before trying to do routing. This means that a task's last output may not make it to the coprocess, though.

Rename vars in coprocess to make more sense. Get rid of NSTask. Only allow one coprocess. Allow it to be stopped. Rename interactivescripttrigger. Make PTYTask route coprocess io and waitpid on coprocess jobs. Show icon when coprocess is rurnning.

Keep process cache up to date in a new thread to avoid blocking the UI loop when the CPU is slammed and there are many processes. Fixes bug 804.

Stop running login; instead detect the user's shell and launch it with - as the first char of argv[0]. Also change how locale is detected. Fixes bug 588.

Second try to fix Sparkle hang. Keep a list of pids that need to be wait()ed on and wait() on them until they're good and dead. Fixes bug 475. Fixes bug 458.

Add iTerm2-specific Expose mode. Fixes bug 306. Formatting, dead code fixes. Improve PTYTab's image code to not draw an enormouse frame into a tiny view, and to draw the visible part; also to draw a proper background for splitters and scrollview.

Integrate changes from juhagman's branch at r390. Fix lead of DVR buffer. Introduce PTYTab abstraction in preparation for split panes.  Only show tabs in fullscreen mode if the cmd key alone is depressed.  Introduce SessionView in preparation for split panes. Fix a bug where you try to enter IR with no frames due to lack of memory in buffer for even one frame.  Fixed some memory leaks.
