6ed9e9f32f zfs: correctly calculate dn_bonuslen for saving SAs to disk
Since all attribute values start at 8-byte aligned boundary, we would
previously incorrectly calculate dn_bonuslen if any attribute but the
last had a variable-length value with length not multiple of 8.

9c5c3cafbd zfs: fix sa_modify_attrs handling of variable-sized attributes
- skip length_idx index for a replaced variable-sized attribute
- skip length_idx index for a removed variable-sized attribute
- also re-arranged code to make sure that length_idx is always
  incremented for variable-sized attributes
- additionally add an assertion that the number of actually produced
  attributes is the same as the expected number of resulting
  attributes

571e19b341 Update copyright information in several ZFS files, as the clause 3.3
of the CDDL licence explicitly requires every Contributor to add
a copyright notice.

This also reflects the copyright notices for the changes recently
added by Illumos.

4aadb12e0b Fix a bug in sa_find_sizes() which could lead to panic:
When calculating space needed for SA_BONUS buffers,
hdrsize is always rounded up to next 8-aligned boundary.
However, in two places the round up was done against
sum of 'total' plus hdrsize.  On the other hand,
hdrsize increments by 4 each time, which means in
certain conditions, we would end up returning with
will_spill == 0 and (total + hdrsize) larger than
full_space, leading to a failed assertion because
it's invalid for dmu_set_bonus.

10b9d77bf1 Finally... Import the latest open-source ZFS version - (SPA) 28.
Few new things available from now on:

- Data deduplication.
- Triple parity RAIDZ (RAIDZ3).
- zfs diff.
- zpool split.
- Snapshot holds.
- zpool import -F. Allows to rewind corrupted pool to earlier
  transaction group.
- Possibility to import pool in read-only mode.
