Subject: [PATCH] motorRecord.cc: Make sure that ACCS/ACCU are initialized

When the record is initialized, it could happen that the ACCS field
was not initalized at all.
Fix this:
- Introduce a new value for motorACCSused, motorACCSused_Undef.
  This is == 0, and temporally used until the record is initilized.
  Using 0 as Undef will allow a (mis-) use in e.g. CSS to make the ACCS
  field invisable, whe ACCU is 0
  (or not present at all in an older version of the motorRecord)
- At the end of check_speed_and_resolution() set ACCS and ACCU, if needed.
