and kern.cam.ctl.disable tunable; those were introduced as a workaround
to make it possible to boot GENERIC on low memory machines.
With ctl(4) being built as a module and automatically loaded by ctladm(8),
this makes CTL work out of the box.

In case where there are no static kernel environment entries, the
function init_dynamic_kenv() adds an incorrect entry at position 0 of
the dynamic kernel environment. This in turn causes kenv(1) to print
and empty list even though there are dynamic entries added later.
Fix this by checking env_pos in init_dynamic_kenv() and adding dynamic
entries only if there are static entries.

- Casting to long double isn't needed.
- The division isn't needed, multiplication can be used.
"When 1 nanosecond is in a floating point literal, the whole
expression is automatically promoted correctly."
- non-KNF indentation (1 tab) for the newly split line
- different non-KNF indentation (5 spaces) for the previously split
line
- exessive parentheses around the division operation
- bogus blank line which splits up the etime initialization
- general verboseness from the above.

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.

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.

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.
