[NTG-context] lmtx upload

[Hans Hagen]

Hi,

I uploaded the first 2023 lmtx. There are not that many changes, most 
relate to updating manuals. Currently we're looking at the metafun / 
luametafun and lowlevel manuals - adding some accumulated todo's.

Keep in mind that when we update manuals that is is not automatically 
reflected in new pdf's (processing happens outside the tree on temporary 
paths) and only occasionally I push back a pdf (when it looks ok). So, 
manual sources can be more up to date than manual pdfs. If you feel 
something (fundamental and stable) is missing you can let us know here.

We gained some performance over the last month, mostly due to using 
different low level mechanisms (there are some more not yet widely used 
ones). The gain depends on (extreme) usage so quite likely most goes 
unnoticed unless one has many runs. After all, there are no fundamental 
changes in context, which is already reasonable optimized for ages (it's 
kind of a game to make it faster without obscuring the code, which is a 
criterium for rejection).

As usual, (new and old) bugs will be fixed,

Hans
