[why] DML itself is SW only, putting the logic as part of resource makes it hw dependent and thus impossible to compile separately from dc. Separate compilation is critical for unit testing as well as bbox tool development [how] create new dml wrapper. Copy logic from the validation functions into dml wrapper as base implementation. Dml wrapper has internal/static implementations for all helpers, and does not reference other functions. It may reference dc structures/types for convenience. This change now has all the changes for DML isolation squashed into one. Reviewed-by:

[Why] The link encoder assignment leaves the old stream data when it was unassigned. When the clear encoder assignment is called, it based on the old stale data to access the de-allocated stream. [How] There should be no need to explicitly clean up the link encoder assignment if the unassign loop does the work properly, the loop should base on the current state to clean up the assignment. Also, the unassignment should better clean up the values in the assignement slots as well. Reviewed-by:

[Why] A built firmware binary may be aligned to 16-bytes with padding at the end as necessary. In the case that padding was applied the meta info will not be detected correctly and we won't be able to allocate the appropriate firmware and tracebuffer sizes. [How] To maintain compatibility with already released firmware where this occurs we need to try every meta offset from 0..15 inclusive. Extract out the meta info checker into a helper function that's called for each of these offsets and exit early when we've found it. Reviewed-by:
