Some personal stuff I'd like.
* Fix 'invalid character' in META (use . instead of +).
* Don't mess with META:Release.
  + Do the original META:Release messing if the file .official exists.
* Support new option --linuxdir to specify location of kernel source tree.
  + Use --with-linux{-obj} values from previous ./configure run.
  + Use --with-spl{-obj} values from previous ./configure run.
  + _configure was specified earlier, but never used. Use it!
* Remove '-g -O2' when building zvol_id.
  + crashes on 64bit kernel with 32bit userland.
* Add --keep-version to alien
  + So that not all packages end up with <version>-0.

Merge some SMBFS fixes from smbfs_fixes.
  * Update manpage with more information about the ACL, guest access
    and that samba needs to be able to authenticate user(s).
  * Add information that 'net' can be used to modify the share after
    ZFS sharing and that it will be undone with a 'zfs unshare'.
    Closes: #1181
  * Do basic sanity checks in smb_available() to verify that the 'net'
    command and the usershare directory exists.
    Closes: #1124
  * Give an example on how to mount a SMB filesystem shared via ZFS.
    Improves: #1170
This is iSCSI sharing for ZoL (shareiscsi).
