port updated configuration from 21.0 to master

See merge request !1044

Replaced #defines for T/P Converters that were needed after the conveter
move to the new package TPTools and name changes, with typdefs. That was
always intended but did not work with GCCXML so a #define hack was used.
Also cleaned up the associated #includes.
Conveter names on the user side were not renamed this time.

Use tempMaskedChips and abcdErrorChips information (ATLASRECT-4013).
