fix two unbounded-loop hangs

[hampushellsberg-dev]

PR re-issue using correct master branch

Add cycle detection to resolve_type_name and resolve_type_descriptor in compiler.py so that circular tagged types raise CompileError instead of looping forever.

Add a missing check_decode_error call in ArrayType.decode_content (der.py) so that malformed SEQUENCE OF / SET OF data raises DecodeTagError instead of looping forever.

nice, any chance you can make the code styling/formatting look more like the rest of the code? Remove some doc strings, put blank lines in correct positions.
