Subject: [PATCH 01/11] Add sequences and signals for desktop notification

Add sequences
  OSC 777 ; notify ; SUMMARY ; BODY BEL
  OSC 777 ; notify ; SUMMARY BEL
  OSC 777 ; notify ; SUMMARY ; BODY ST
  OSC 777 ; notify ; SUMMARY ST

that let terminal applications send a notification to the desktop
environment.

Based on Enlightenment's Terminology:

Subject: [PATCH 02/11] vte.sh: Emit OSC 777 from PROMPT_COMMAND

For some reason, the three consecutive backslashes break the parsing.
As Christian Persch suggested, replacing the double quotes with
singles fixes it.

By default, it is set to zero which gives the current behaviour of
moving the buffer by a function of the number of visible rows.

Subject: [PATCH 06/11] Support preexec notifications from an interactive shell

Add sequences

Examples of such hooks are Bash's PS0 and Zsh's preexec.

Subject: [PATCH 10/11] Support tracking the active container inside the
 terminal

Add sequences

  OSC 777 ; container ; push ; NAME ; RUNTIME ; UID BEL
  OSC 777 ; container ; push ; NAME ; RUNTIME ; UID ST
  OSC 777 ; container ; pop ; NAME ; RUNTIME ; UID BEL
  OSC 777 ; container ; pop ; NAME ; RUNTIME ; UID ST

  OSC 777 ; container ; push ; NAME ; RUNTIME BEL
  OSC 777 ; container ; push ; NAME ; RUNTIME ST
  OSC 777 ; container ; pop ; NAME ; RUNTIME BEL
  OSC 777 ; container ; pop ; NAME ; RUNTIME ST

that let container tools notify the terminal emulator when entering and
leaving a container environment. The RUNTIME argument namespaces the
NAME and identifies the container tooling being used. eg., docker,
flatpak, podman, toolbox, etc.. The UID argument is the real UID of the
container tools. Only those containers that are used with the same real
UID as the VTE process are tracked.

The OSC 777 escape sequence is taken from Enlightenment's Terminology:
https://phab.enlightenment.org/T1765

It's a VTE-specific extension until a standard escape sequence is
agreed upon across multiple different terminal emulators [1].
