Fix iTunes backups support and unify keychain code

[GoogleCodeExporter]

The scripts for decrypting itunes backups wont work with ios 5 because they use 
the mdbx index file that is no longer created by itunes.

iOS 5 keychain backup format is also slightly different (same as the on-device 
sqlite changes). Try to unify the keychain code for sqlite and backup formats 
(plist).

The backup_tool.py script in the latest revision should work with ios 5 backups.
