**Issue:**
An important part of terminal applications is the ability to set and
read the system clipboard. This is not possible to test.
**Solution:**
Support an in-memory OSC52 clipboard in the terminal testing session
that can be tested. OSC52 is a terminal escape sequence that allows
terminal applications to set the clipboard contents of the host
terminal. It works locally and even over ssh connections.
Features:
- store the latest clipboard contents in memory, and allow **read-only**
access in tests.
- tests can only read the clipboard contents, not set them.
- the test application (e.g. neovim) can read + write the clipboard
contents normally using OSC52 requests.
- Does not affect the system clipboard of the host system (your
computer), which could disturb other tasks while the tests are
running. Now they are completely separate.
- support both "system" and "primary" clipboards. This is what xtermjs
exposes, and we now support both. The "system" clipboard seems to be
the default on macOS, while "primary" is probably used on Linux X11.
References:
- xtermjs 6.0 added support for OSC52 clipboard requests via
xtermjs/xterm.js#4220
- https://neovim.io/doc/user/provider.html#clipboard-osc52
Closes #857
