Change-Id: If80031678a474157e4cc78a3d3621dab53aded67
Create a dedicated "Exception" sub-namespace and remove the "AFP"
prefix, a leftover from the pre-namespace era.
Change-Id: I7e5fded9316d8b7d1628bc1a6ba8b1879ac901e1
Introduce a clear distinction between internal exceptions and
user-visible exceptions, leaving AFPException as base abstract class.
Later, it should be possible to narrow some types around, e.g. in
ParserStatus (that might work with user-visible exceptions only).
Also a future TODO is putting all the exceptions in their own namespace
(probably ...\Parser\Exception).
