Separated the demo in three sections of 30 seconds each:
- Basics of RPL and user interface (RPL, function keys, online help, catalog,
unicode, text editor)
- Mathematics (complex, vector, matrix, symbolic, based)
- Programming

Showing the address, type and size of RPL objects is not often useful.
It is generally sufficient to just show the object rendering.

Fix clean build of simulator with `make sim`:
- Pass `TARGET=opt` instead of `TARGET=` when building tools
to ensure the tool gets properly built irrespective of environment
- Remove reference to obsolete Intel decimal library, which was still
hanging around in my build directories.

An active timer when calling `sys_sleep()` would keep bringing the
function out of the loop without calling `nanosleep`, which defeats
the purpose of that function to actually sleep.
The solution is to only take a timer into account if it triggered
while the function was running.

Reserve the main thread for display updates and keyboard interaction,
like for the Qt version. This allows the web simulator to work
correctly when you run a program or when you access the firwmare
interface.
The downside is that you need to run that on a web server that is able
to set the following [HTTP headers][coop]:
```
Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin
```
Unfortunately, it is not entirely clear if this can be made to work
easily with [GitHub pages][ghp].

This is an in-tree port of [Franco Trimboli's excellent work][wasm].
The goal is to be able to run the simulator in a browser.
This builds with emscripten, as installed by the `emsdk`.
The `emsdk` is added as a submodule, and initialized on first build.
To build the browser WASM version of the simulator, run `make wasm`.

Remove the `DataMenu`.
Replace `PrintMenu` with `ListMenu` as keyboard-accessible menu
(we can tuck the rarely used `PrintMenu` under `I/O`)
Add list product, sum, etc to `ListMenu`
Modify `ProgramMenu` to add special program entry characters.

The new sync between tests and RPL theads was not working correctly in
the case of `Wait` and `Show` commands because they were popping keys

Split the recorders between `tests` and `tests_rpl`.
Separate the handling of commands into `process_test_commands` and
`process_test_key`, with the key handling happening before we actually
run the code.

The `qApp->primaryScreen()->devicePixelRatio()` method no longer

It looks like gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4) thinks it's a good
idea to complain about every single zero-initialized C structure.
This is widely acknowledged as a (rather annoying)
[GCC bug](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119)
Add a constructor to silence the warning where possible.
For DMCP C structures where this is not possible, well, add ugly code.
With gcc (GCC) 13.2.1 20231011 (Red Hat 13.2.1-4), there is a message about
fall-through switch statements. Add comment to silence the warning when the
fall-through is intentional.
There was one case where the fall-through was not intentional.
Missing `break` added.

These are two catalogs that behave much like the constants catalog,
and inherit most of the code.
The equations library is intended to store standard equations.
The library is for standard objects and various useful objects or

Both can be organized by topics.

Make sure that we capture consistent pixmaps, which we can do on the
RPL thread, and only defer the transfer of the pixmap to the main
thread, which is fast.
Additionally, optimize updates by doing a byte-by-byte xor comparison
in order to see which bytes actually changed. This minimizes the cost
on the RPL thread to update the pixmap.
This makes it possible to have a much better screen behaviour for the
`CBench` benchmark, where it updates it regularly on the screen while
not slowing things down too much.
