* RecoveryState is updated before confirmation(s)
* New confirmation prompt that supports both cloning and imaging modes
* Refactored show_selection_details() to use new objects
* Allows resumed state to be detected and prompt switched to "Resume?"
* Renamed function show_safety_check() to double_confirm_clone() for clarity
* Dest/map paths are now set in two steps:
* The filename prefix is set when creating the DevObj()
* The full paths are set when creating the BlockPair()
* Merged dest safety checks into RecoveryState.add_block_pair()
* Mostly check_dest_paths() and dest_safety_check()
* Moved dir RWX checks to is_writable_dir()
* Moved mount RW check to is_writable_filesystem()
* Started merging menu_clone() and menu_image() into menu_ddrescue()
* Colored report data is generated during obj instantiation
* Code has been moved into its own function
* Entire colored string is now stored for each Obj
* (Should make show_selection, etc more mode/Obj agnostic)
* loopback_dev vs image_path is now better separated
* losetup is called in ImageObj.set_details()
* loopback -D is still called during program cleanup/wrapup
* get_device_size_in_bytes() has been renamed get_size_in_bytes()
* load_map() is called on BlockPair() instantiation
* This partially replaces resume_from_map()
* Also fixed improper method declarations lacking the self argument
Added two classes:
* BlockPair()
* Track source/dest pair specific data
* update_progress() method for its own data
* RecoveryState()
* Track BlockPair objects and overall state
* update_progress() method for overall data
Reasons:
* Code readability
* Better status updates, code currently split between:
* get_recovery_scope_size()
* resume_from_map()
* update_progress()
* Functions that should probably be merged into other functions:
* get_recovery_scope_size()
* set_dest_image_paths()
* check_dest_paths()
* Logic that needs to be cleaned up:
* Calculating overall recovery size
* Pass "Done"ness and status strings need separated
* Pass "Done"ness at the device and overall levels
* Updating output for side pane status display
