James Hawkins 4dded613b3 bootstat: Fix a potential unhandled exception for malformed input. 
In rare cases the hardware storage on the device may be hosed and return
garbage.  Use ParseInt which handles bad input instead of stoi.

James Hawkins c0dc139b4a Revert "Revert "bootstat: Handle v1 record files which do not contain file contents.""
