[ Merge of http://go/wvgerrit/171310 ] Offline license not found errors are identified by CdmResponseEnum 347 (KEYSET_ID_NOT_FOUND_4). No addition file system information is shared. Checks for file existance use the stat command. The stat call can return error codes from errno.h when the command fails. These are now converted into sub error codes and returned along with the offline license file not found error. This also includes a change to log stat errors other than ENOENT (no such file or directory) as a warning rather than verbose. Bug: 276225520 Test: file_store_unittest, file_utils_unittest, GtsMediaTestCases Change-Id: Ic09d036549582cd65783b49fa96ffefc4bf562c7
