* support extended attributes
* bump major due to structure growth
* add some spare space
* remove ABI sillyness
Support extended attributes.
Fix multiple non compliances in our Linux-like extattr API, and make it
public so that it can be used.
Improve a bit listxattr(2). It attemps to list both system and user
extended attributes, and it faled if calling user did not have privilege
for reading system EA. Now we just lise user EA and skip system EA in
reading them is not allowed.
Fix bug introduced in previous commuit: Do not vrele() a vnode we did not
obtained.
Improve UFS1 extended attributes usability
- autocreate attribute backing file for new attributes
- autoload attributes when issuing extattrctl start
- when autoloading attributes, do not display garbage warning when looking
up entries that got ENOENT
Add a flag to VOP_LISTEXTATTR(9) so that the vnode interface can tell the
filesystem in which format extended attribute shall be listed.
There are currently two formats:
- NUL-terminated strings, used for listxattr(2), this is the default.
- one byte length-pprefixed, non NUL-terminated strings, used for
  extattr_list_file(2), which is obtanined by setting the
  EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9)
This approach avoid the need for converting the list back and forth, except
in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may
have requested EXTATTR_LIST_PREFIXLEN.
