Implement PetscBT with new PetscByte datatype as unsigned char

Fix the inconsistent usage of #if [!]defined XXX compared to defined(XXX)

Thanks-to: Pierre Jolivet

An LLM Claude detected the incosnsitency it was not used to remove the inconsistency

Remove the last of the use of horizontal lines --- as seperators. With modern code development systems they are not needed and just an eye-sore
