Interdependent, failing commits

[Stephan Bergmann]

The two recent commits 
<https://git.libreoffice.org/core/+/d8e29e2697e90da6acf5858fd74d6054ed9e5aa3%5E%21> 
"Revert 'Revert 'stronger typing for SwClient::GetRegisteredIn'' and fix 
SwIterator cast" and 
<https://git.libreoffice.org/core/+/404fbec25740406e3b926844f3bd0f324dc38b8c%5E%21> 
"convert RES_ATTRSET_CHG to SfxHint" are both known-broken and cause at 
least UBSan builds to fail (see the comments at 
<https://gerrit.libreoffice.org/c/core/+/179480/3#message-1d186afad4accdcf814507953175bf0e483b0e2e> 
and 
<https://gerrit.libreoffice.org/c/core/+/179772/6#message-e7324ab2f8feb8f37c28a4f8845176d82f658648>, 
respectively).

Now, a third commit 
<https://git.libreoffice.org/core/+/404fbec25740406e3b926844f3bd0f324dc38b8c%5E%21> 
"convert RES_ATTRSET_CHG to SfxHint" interferes with (local) reverts of 
the other two commits, so it becomes increasingly messy to try and keep 
a successful (local) UBsan build, and keep an eye on further commits 
that could potentially introduce further/unrelated breakage.

Therefore, unless there are fixes for the two known-broken commits 
available by then, I suggest to revert for now all three of those 
commits tomorrow evening.
