Colm 1f3de97374 Improvements to the 'compatibility' property
Several improvements to the operation of the 'compatibility' property:

1) Improved handling of unrecognized features:
Change the way unrecognized features in compatibility files are handled.

 * invalid features in files under /usr/share/zfs/compatibility.d
   only get a warning (as these may refer to future features not yet in
   the library),
 * invalid features in files under /etc/zfs/compatibility.d
   get an error (as these are presumed to refer to the current system).

2) Improved error reporting from zpool_load_compat.
Note: slight ABI change to zpool_load_compat for better error reporting.

3) compatibility=legacy inhibits all 'zpool upgrade' operations.

4) Detect when features are enabled outside current compatibility set
   * zpool set compatibility=foo <-- print a warning
   * zpool set feature@xxx=enabled <-- error
   * zpool status <-- indicate this state
