Coalesce ERRL user detail data error log sections

Add optional 'merge' flag to addFFDC() method which certain UserDetail
error log objects will use to cause additional log entries to get
merged together. They will ONLY get merged if they match with the
last section added, to preserve error log order.

In addition, add support for an addData() method on the Attributes
User Detail class. And re-organize code so that constructor methods
are smaller, making final library smaller.

NOTE - the parse() functions are NOT complete, since building and
executing the hb errlparser tool is currently broken. Story 41707
is open to do that work once the tool builds.
