bc96366c86 Mechanically convert cddl sun #ifdef's to illumos
Since the upstream for cddl code is now illumos not sun, mechanically
convert all sun #ifdef's to illumos #ifdef's which have been used in all
newer code for some time.

Also do a manual pass to correct the use if #ifdef comments as per style(9)
as well as few uses of #if defined(__FreeBSD__) vs #ifndef illumos.

ZFS large block support.

Please note that booting from datasets that have recordsize greater
than 128KB is not supported (but it's Okay to enable the feature on
the pool).  This *may* remain unchanged because of memory constraint.

Limited safety belt is provided for mounted root filesystem but use
caution is advised.

2bdf7f79bc MFV r266766:
Add a new zfs property, "redundant_metadata" which can have values "all" or
"most".  The default will be "all", which is the current behavior.  When set
to all, ZFS stores an extra copy of all metadata.  If a single on-disk block
is corrupt, at worst a single block of user data (which is recordsize bytes
long) can be lost.

Setting to "most" will cause us to only store 1 copy of level-1 indirect
blocks of user data files.  This can improve performance of random writes,
because less metadata has to be written.  In practice,  at worst about
100 blocks (of recordsize bytes each) of user data can be lost if a single
on-disk block is corrupt.

The exact behavior of which metadata blocks are stored redundantly may change
in future releases.

Illumos issue: 3835 zfs need not store 2 copies of all metadata

537650f54d Add property and sysctl to control how ZVOLs are exposed to OS.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
 geom -- existing fully functional behavior (default);
 dev -- exposing volumes only as raw disk device file in devfs;
 none -- not exposing volumes outside ZFS.

The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.

Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

83b4af1142 ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl()
doesn't copyout in this case.

To solve this issue a new struct zfs_iocparm_t is introduced consisting of:
- zfs_ioctl_version (future backwards compatibility purposes)
- user space pointer to zfs_cmd_t (copyin and copyout)
- size of zfs_cmd_t (verification purposes)

The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way
what makes porting of new changes easier and ensures correct behavior if
returning an error.

bb508e7732 Fix the zfs_ioctl compat layer to support zfs_cmd size change introduced
in r247265 (ZFS deadman thread). Both new utilities now support the old
kernel and new kernel properly detects old utilities.

For future backwards compatibility, the vfs.zfs.version.ioctl read-only
sysctl has been introduced. With this sysctl zfs utilities will be able
to detect the ioctl interface version of the currently loaded zfs module.

As a side effect, the zfs utilities between r247265 and this revision don't
support the old kernel module. If you are using HEAD newer or equal than
r247265, install the new kernel module (or whole kernel) first.

ef17620fc8 MFV r245512:
* Illumos zfs issue #3035 [1] LZ4 compression support in ZFS.

LZ4 is a new high-speed BSD-licensed compression algorithm created
by Yann Collet that delivers very high compression and decompression
performance compared to lzjb (>50% faster on compression, >80% faster
on decompression and around 3x faster on compression of incompressible
data), while giving better compression ratio [1].

This version of LZ4 corresponds to upstream's [2] revision 85.

Please note that for obvious reasons this is not backward read
compatible.  This means once a pool have LZ4 compressed data, these
data can no longer be read by older ZFS implementations.

Local changes:

 - On-stack hash table disabled and using kernel slab allocator
   instead, at this time.  This requires larger kernel thread stack
   for zio workers.  This may change in the future should we adjusted
   the zio workers' thread stack size.
 - likely and unlikely will be undefined if they are already defined,
   this is required for i386 XEN build.
 - Removed De Bruijn sequence based __builtin_ctz family of builtins
   in favor of the latter.  Both GCC and clang supports these builtins.
 - Changed the way the LZ4 code detects endianness.
 - Manual pages modifications to mention the feature based on Illumos
   counterpart.
 - Boot loader changes to make it support LZ4 decompression.

For snapshots, this is the same as COMPRESSRATIO, but for

538e86713d Fix misalignment in nvpair_native_embedded() caused by the compiler
replacing the bzero(). See also revision 195627, which fixed the
misalignment in nvpair_native_embedded_array().

dd8a461e83 In nvpair_native_embedded_array(), meaningless pointers are zeroed.
The programmer was aware that alignment was not guaranteed in the
packed structure and used bzero() to NULL out the pointers.
However, on ia64, the compiler is quite agressive in finding ILP
and calls to bzero() are often replaced by simple assignments (i.e.
stores). Especially when the width or size in question corresponds
with a store instruction (i.e. st1, st2, st4 or st8).

The problem here is not a compiler bug. The address of the memory
to zero-out was given by '&packed->nvl_priv' and given the type of
the 'packed' pointer the compiler could assume proper alignment for
the replacement of bzero() with an 8-byte wide store to be valid.
The problem is with the programmer. The programmer knew that the
address did not have the alignment guarantees needed for a regular
assignment, but failed to inform the compiler of that fact. In
fact, the programmer told the compiler the opposite: alignment is
guaranteed.

The fix is to avoid using a pointer of type "nvlist_t *" and
instead use a "char *" pointer as the basis for calculating the
address. This tells the compiler that only 1-byte alignment can
be assumed and the compiler will either keep the bzero() call
or instead replace it with a sequence of byte-wise stores. Both
are valid.

0970b4bae0 MFp4 changes neccessary for NFSv4 ACLs support in ZFS. This is mostly
about removing a few #ifdefs and providing compatibility wrappers and
VOP implementations to get and set an ACL; ZFS does ACL enforcement all
by itself.

Note that the VOPs are ifdefed out for now, so this change should be
a no-op.
