    libhammer - Preparation for snapshot handling & fixes
    
    Trivial changes:
    	- Function renaming to actually match what they are
    	  describing.
    	- Clearer variable naming.
    
    Additions:
    	- Structures to hold snapshot data.
    	- Functions to retrieve snapshots from metadata for PFSes.
    	- A file for version compatibility functions.
    	- A function to return the canonical access path of a
    	  PFS which is suitable for opening.
    	- Wrappers to operate per PFS snapshot list.
    
    Changes & fixes:
    	- Use the new functions to gather all snaps of a PFS.
    	- Adapt hammer program for the changes.
    	- Check before free'ing in libhammer_free_fsinfo()
    	- Display the number of snapshots for unmounted PFSes.
    
    Still missing:
    	- Manpages changes.
