FatFS and general file operations fixes

Browse source 
* Make FatFS thread safe via malloc and remove alloca.
* Fix memory leak from emmc gpt parsing
* Always unmount SD card in menu and when launching
* Use folders for Backup/Dump/Restore operations
* Add error report for some important f_opens
* Don't let partial dumping if backup chosen is not GPP or USER.
