A bit of reorganization in C/shell code.

With these changes:
 - Added 'sanitize-plist' action to xbps-pkgdb. It takes a plist
   file as argument and writes another one "sanitized" by proplib.
   Use it to sanitize the pkgindex plist file.
 - Split xbps-pkgdb functions to be shared by other files.
 - Split xbps-digest functions to be shared by other files.
 - Rename the plist file to register/unregister installed pkgs to
   regpkgdb.plist, and related stuff in shell scripts.
