[illumos-Developer] Review: 742 Resurrect the ZFS "aclmode" property and 279, 664, 807

[Albert Lee]

I'd like to request comments on:
http://pkgdev.openindiana.org/~trisk/aclmode/

279 Bug in the new ACL (post-PSARC/2010/029) semantics
664 Umask masking "deny" ACL entries.
742 Resurrect the ZFS "aclmode" property
807 Trivial ACEs missing delete

For background information, see (this also links to the related bugs):
https://www.illumos.org/issues/742

This reintroduces the "aclmode" ZFS property removed in
PSARC/2010/029. The new "aclmode" only applies to chmod(2) operations,
whereas prior to its removal in PSARC/2010/029 there were poorly
defined interactions with inherited ACEs for newly created files.

279 and 664 were introduced by changes for PSARC/2010/029. 807 affects
interaction with Windows CIFS clients.
