Subject: MD5 verification sanity

We can use switches and enums to make things more understandable
and work with results in a more sensible manner.

PS2: Move file MD5 verification and error handling into
     a separate function to reduce code.

PS3: Default to false in Check_Restore_File_MD5 function

(cherry picked from commit 5c3950716e5c7c6279efd5f3f338d6d22e5215e2)
