o Caused FFS_EXTATTR_AUTOSTART to scan two sub-directories of ".attribute"

Browse Source 
off of the file system root: "user" for user attributes, and "system"
  for system attributes.  When the scan occurs, attribute backing files
  discovered in those directories will be started in the respective
  namespaces.  This re-introduces support for auto-starting of user
  attributes, which was removed when the "$" prefix for system attributes
  was replaced with explicit namespacing.

  For users of the TrustedBSD UFS POSIX.1e ACL code, you'll need to:
    mv ${FSROOT}/'$posix1e.acl_access' ${FSROOT}/system/posix1e.acl_access
    mv ${FSROOT}/'$posix1e.acl_default' ${FSROOT}/system/posix1e.acl_default

  For users of the TrustedBSD POSIX.1e Capability code, you'll need to:
    mv ${FSROOT}/'$posix1e.cap' ${FSROOT}/system/posix1e.cap

  For users of the TrustedBSD MAC code, you'll need to:
    mv ${FSROOT}/'$freebsd.mac' ${FSROOT}/system/freebsd.mac

  Updated versions of relevant patches will be released in the near
  future.
