fae28006cf Move scroll handling to GDScript
Just expose the underlying libtsm methods from gdnative, but write all
the logic in gdscript. Makes it much easier to customize and update.

- Adds misc/gen_3rdparty_licenses.sh file to generate the above
  mentioned text files.
- Seperated node_pty and tmux licenses.

Add disable_pty compile option
If disable_pty=yes then the PTY node and dependencies (LibuvUtils, Pipe)
will be excluded. On platforms where the PTY node is not supported (e.g.
HTML5), this will always be equivalent to `disable_pty=yes`.

0dd2378387 Add new PTY node (replaces Pseudoterminal node)
Uses fork of node-pty native code for forking pseudoterminals.
Uses libuv pipe handle to communicate with the child process.

- Paves the way for cross-platform (Linux, macOS and Windows) support.
- Renames Pseudoterminal to PTY (which is much easier to type and spell :D).
- Better performance than the old Pseudoterminal node. Especially when
  streaming large amounts of data such as running the `yes` command.
- Allows setting custom file, args, initial window size, cwd, env vars
  (including important ones such as TERM and COLORTERM) and uid/gid
  on Linux and macOS.
- Returns process exit code and terminating signal.

bfa561357e Yield for "frame_pre_draw" signal before writing to terminal
Fixes #41. But creates another issue where sometimes the yield will
resume after the terminal node has already been freed logging an error
to the console.

Also a few changes to where update is called it the gdnative terminal
code.

Also changed gdnative terminal to only accept strings.

Load default theme if it exists
This also means that we can load default fonts from it. Falling back to
the default Godot font if no theme is set and the default theme does not
exist.

Having an actual theme loaded also allows live font resizing.

a337143949 Add libtsm patches for some escape sequences
The sequences are:
  CSI > Pp ; Pv m    (e.g. '\e[>4;m'
  CSI ? Pm $ p       (e.g. '\e[?12$p'

These sequences were being output by vim and causing the underline
attribute to be set and the terminal to be reset.

Fixes #40

Multiple updates
- Use viewport as render target for terminal:
  Terminal now only draws cells which changed since the last _draw() call.
  A viewport is used with clear mode set to NEVER to cache previous draw
  calls. The terminal node and viewport are wrapped by a GDScript Terminal
  node which takes care of resizing the viewport scene, and forcing the
  terminal to redraw all cells when necessary (i.e. on resize or theme
  change).

  Adds update_mode to terminal interface which can be set to one of:
  - DISABLED: terminal will never be drawn
  - AUTO: terminal will only draw the cells that changed, but
    automatically redraw the full screen when necessary (for example,
    when the size or theme changed).
  - ALL: terminal will always draw every cell on every update. This is
    the most reliable but least performant option.
  - ALL_NEXT_FRAME: Will use update_mode ALL for the next _draw() call,
    then change update_mode back to AUTO.

- Upgraded libtsm:
  Includes changes from Fredrik Wikstrom (salass00)'s fork of libtsm.

- Don't require theme to be set.
  Terminal will use default fonts/colors if no theme is set.

Use gdnative api to get constants only for javascript platform
When trying to load the library in a non-Mono Godot editor v3.3.2
an error is printed about godot_get_global_constants(). Furthermore,
the issue with using the GlobalConstants header to get constants is only
present on the javascript platform, so we can revert all other platforms
to the old way of getting constants.

empty. Check if they are empty and update submodules. Previously,
submodules where only updated if their directories did not exist.

fbb23661d3 Get KeyList constants from GDNative API
Previously KeyList constants came from the GlobalConstants.hpp header,
but this did not work when compiling for HTML5. Therefore, we now get
the globals constants from the GDNative API.

Throws the error:
`LNK2019: unresolved external symbol godot_get_global_constants referenced in function "private: static void __cdecl godot::Terminal::_populate_key_list(void)" (?_populate_key_list@Terminal@godot@@CAXXZ)`
in GitHub Windows action. So use the old technique on Windows for now.

This is a prerequisite for HTML5 support.

b2dc46636c Update github actions workflow
- Uses matrix so that build steps don't need to be defined multiple

- Caches godot-cpp bindings, so they only need to be built when the
  submodule version changes.
- Uploads build artifacts for linux 32/64-bit, windows 64-bit and macOS
  64-bit.
