Update ciss(4) man page.  We absolutely support performant mode of operation
on this controller.  Indicate that the 5300 is the *only* controller that
will only work in simple mode.

Bus rescans should not be needed now and I consider it a bug if disks do
not appear or dissapear when created or destroyed.

Do not sent 120 TEST UNIT READY requests on generic NOT READY statuses.

Some failing disks tend to return vendor-specific ASC/ASCQ codes with
NOT READY sense key.  It caused extremely long recovery attempts, repeating
these 120 TURs (it takes at least 1 minute) for every I/O request.
Instead of that use default error handling, doing just few retries.

Fix libzfs to report error instead of returning zero if trying to hold or
release a non-existing snapshot of a existing dataset. In recursive case
error is reported if no snapshots with the requested name have been found.

DTrace: option for time-ordered output

Merge changes from illumos:

3021 option for time-ordered output from dtrace(1M)
3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work
3025 register leak in D code generation
3026 libdtrace should set LD_NOLAZYLOAD=1 to help the pid provider

This brings yet another feature implemented in upstream DTrace.
A complete description is available here:
http://dtrace.org/blogs/ahl/2012/07/28/my-new-dtrace-favorite/

This change bumps the DT_VERS_* number to 1.9.1 in
accordance to what is done in illumos.

This change was somewhat complicated because upstream is mixed many
changes in an individual commit and some of the tests don't really
apply to us.

There are also appear to be differences in timestamping with Solaris
so we had to workaround some assertions making sure no regression
happened.

Special thanks to Fabian Keil for changes and testing.

Remove kernel options from the SYNOPSIS. They are already documented in the
geom(4) manual page SYNOPSIS.
Fix tcp_output() so that tcpcb is updated in the same manner when an
mbuf allocation fails, as in a case when ip_output() returns error.

To achieve that, move large block of code that updates tcpcb below
the out: label.

This fixes a panic, that requires the following sequence to happen:

1) The SYN was sent to the network, tp->snd_nxt = iss + 1, tp->snd_una = iss
2) The retransmit timeout happened for the SYN we had sent,
   tcp_timer_rexmt() sets tp->snd_nxt = tp->snd_una, and calls tcp_output().
   In tcp_output m_get() fails.
3) Later on the SYN|ACK for the SYN sent in step 1) came,
   tcp_input sets tp->snd_una += 1, which leads to
   tp->snd_una > tp->snd_nxt inconsistency, that later panics in
   socket buffer code.
