xtables regression with LMTX 2022-12-21

With the latest (2022-12-21) LMTX I see a regression in xtables. The 
following code:

    \starttext
    \startxtable
       \startxrow
         \startxcell
               This is a line of text.
         \stopxcell
         \startxcell
               \contextversion
         \stopxcell
       \stopxrow
    \stopxtable
    \stoptext


produces this with 2022-12-09:

and this with 2022-12-21:

The problem appears to be LMTX-specific. (I did not save 2022-12-15 for 
testing, but did not see the problem with that version.)

Hi Rik,

I can confirm that the regression only arises in LMTX and in current
latest. With LMTX from 2022.12.15 18:12, the xtable is fine.

It seems to be related to the replacement of \newdimen and \newcount
with \newdimension and \newinteger (which Hans mentioned in
https://mailman.ntg.nl/pipermail/ntg-context/2022/107452.html).

Just in case it helps,

Pablo

Indeed, one has to be careful with aliasing them (frozen values). There 
might be a few more places that need a fix.

thanks for noticing, i uploaded a new lmtx

as a reward i'll reveal a new mechanism:

\useMPlibrary[dum]

\definetextdisplay[steppedbystep][before={\blank[halfline]}]

\starttext \showmakeup[line]
   \dostepwiserecurse{10}{25}{1}{
       xxxxxxxxxxxxxxxx\par
       \starttextdisplay
         \externalfigure[dummydummy][height=#1mm,text=no]%
       \stoptextdisplay
       xxxxxxxxxxxxxxxx\par
       \starttextdisplay[before=\blank,after=\blank] % factor=.5
         \externalfigure[dummydummy][height=#1mm,text=no]%
       \stoptextdisplay
       xxxxxxxxxxxxxxxx\par
       \startsteppedbystep
         \externalfigure[dummydummy][height=#1mm,text=no]%
       \stopsteppedbystep
       xxxxxxxxxxxxxxxx\par
       \page
   }
\stoptext

this uses a new boxtype, compare

\ruledvbox{test\par test}

\ruledvtop{test\par test}

\ruleddbox{test\par test}

and guess what happens. Still in exploration mode.
