IVGCVSW-6428 Remove asserts

 * Changed asserts to check for errors and return appropriate values or
   throw exceptions
 * Changed unit tests to use Doctest's long macro names as the short
   macro names clashed with Android's Logging macros
 * Removed unused #includes
 * Clarified ambiguous #includes
