Christopher Tate 02abe53d8a Add file mode to the file-backup saved state blobs ... This change puts the file's access mode into the saved-state blob used by the file backup helpers. The tests have been updated for the new blob content format. What this change *doesn't* do is actually backup/restore the file mode. This change is a prerequisite for that, but mode preservation in backup/restore will require adding metadata to the backup data stream itself, so will be approached a bit more carefully. (Also fixed one outright bug in the test program: ReadEntityData() had been changed to return a ssize_t union of either a byte-count or a negative number indicating error, but the test program was still assuming that nonzero == error, and was spuriously failing.)		2013-07-30 13:56:51 -07:00
