This patch has been slightly modified from the upstream Illumos
version to be compatible with Linux. Due to the very limited
stack space in the kernel a lz4 workspace kmem cache is used.
Since we are using gcc we are also able to take advantage of the
gcc optimized __builtin_ctz functions.
Support for GRUB has been dropped from this patch. That code
is available but those changes will need to made to the upstream
GRUB package.
Lastly, several hunks of dead code were dropped for clarity. They
include the functions real_LZ4_uncompress(), LZ4_compressBound()
and the Visual Studio specific hunks wrapped in _MSC_VER.

The only valid options are -vnFu, these other ones seem to be
misplaced zfs send options.

Add the initial support for the 'smbshare' option using the
existing libshare infrastructure. Because this implementation
relies on usershares samba version 3.0.23 is required.

Add support for the `zfs list -t snap` alias which is available under
Oracle Solaris 11.

For consistency, and because it's handy, add the 'zfs snap' alias which
was introduced by Oracle Solaris 11. This includes an update to the
man page to reflect all the available alias (snap, umount, and recv).

The script has been updated to download the latest documentations
packages for Solaris and extract the needed ZFS man pages. These
will still need a little markup to handle changes between the
Solaris and Linux versions of ZFS. Howver, they should be pretty
minor I've tried hard to keep the interface the same.
In additional to the script update the zdb, zfs, and zpool man
pages have been added to the repo.
