Remove all trace of Qt4 support. The different elements have been
considered carefully before removal.
The only changes that need to be done concern Windows and macOS
compilation instruction and will need to be taken care of by the
respective maintainers before prerelease.
The file TODO.killqt4 lists what remains to be done.
Reorganize things to do in to point to the macOS and Windows
maintainers. These are things tht need to be done before release.
Update autotest/keytest.py, and ignore the other development/ stuff,
which is is obsolete.
This macros are important for particle physicists. Note that the
package hepparticles as distributed in recent texlive does not work
(see #11804) and need to be patched. This is however not something we
can do, and any physicist wanting to use this will have patched his
own version I guess.
I contacted Andy Buckley, the author of the package, who answered that
he is aware of the issue but does not have time right now to fix it.
The workaround is straightforward: on line 176 of hepparticles.sty,
replace "\updefault" by "n".
Two parts:
- add *lots* of definitions to lib/symbols
- add hepparticles and hepnames as simple features in LaTeXFeatures.
The definitions are courtesy of @renyhp, and extracted from the
aforemented packages:

Fixes bug #11804.
We now allow the user to cancel the background process at any point
(via the red "x" in the status bar or Document > Cancel Export), so
we do not need to poll the user with the dialog.
The patch works by setting timeout to "-1" which is treated as a
special value to disable the poll.
Fix (by obviation) #12531 and #9953, which were about the dialog.
An export can be canceled by clicking on the status bar icon or by
executing export-cancel (e.g., via Document > Cancel Background
Process).
The centralized code kills the script and updates the status bar
icons.
No change in functionality intended.
