create reasonably large cache for the keys that is filled when
needed. The previous version was problematic for very large providers
(hundreds of terabytes or serval petabytes). Every terabyte of data
needs around 256kB for keys. Make the default cache limit big enough
to fit all the keys needed for 4TB providers, which will eat at most
1MB of memory.

Skip probing for nonexistent slave devices there.
It allows to avoid false positive device detection under Xen, that caused

The probes and operations themselves will appear in subsequent

This is only a problem if IFS contains digits, which is unusual but valid.
Because of an incorrect fix for PR bin/12137, "${#parameter}" was treated
as ${#parameter}. The underlying problem was that "${#parameter}"
erroneously added CTLESC bytes before determining the length. This
was properly fixed for PR bin/56147 but the incorrect fix was not backed
out.

secondary role. It is possible that the remote node is primary, but only
because there was a role change and it didn't finish cleaning up (unmounting
file systems, etc.). If we detect such situation, wait for the remote node
to switch the role to secondary before accepting I/Os. If we don't wait for
it in that case, we will most likely cause split-brain.

used a global pthread_mutex_t for synchronization. r179417 replaced that
with an implementation that directly used atomic instructions and thr_*
syscalls to synchronize callers to pthread_once. However, calling
pthread_mutex_lock on the global mutex implicitly ensured that
_thr_check_init() had been called but with r179417 this was no longer
guaranteed. This meant that if you were unlucky enough to have your first
call into libthr be a call to pthread_once(), you would segfault when
trying to access the pointer returned by _get_curthread().
The fix is to explicitly call _thr_check_init() from pthread_once().

While in_pseudo() etc. is often used in offloading feature support,
in_cksum() is mostly used to fix some broken hardware.
Keeping both around for the moment allows us to compile NIC drivers
even in an IPv6 only environment without the need to mangle them
with #ifdef INETs in a way they are not prepared for. This will
leave some dead code paths that will not be exercised for IPv6.

Not compiling in and not initializing from inetsw from in_proto.c for
IPv6 only, we need to initialize upper layer protocols from inet6sw.
Make sure to not initialize them twice in a Dual-Stack
environment but only conditionally on no INET as we have done for
TCP for a long time. Otherwise we would leak resources.

When compiling out INET we still need the initialization routines
as well as the tuning and montoring sysctls shared with IPv6.
Move the two send/recvspace variables up from the middle of the
file to ease compiling out the INET only code.

Move the ipport_tick_callout and related functions from ip_input.c
to in_pcb.c. The random source port allocation code has been merged
and is now local to in_pcb.c only.
Use a SYSINIT to get the callout started and no longer depend on
initialization from the inet code, which would not work in an IPv6
only setup.

- If a ENH_SENS TLV section exit the firmware is capable of doing
enhanced sensitivity calibration.
- Newer devices/firmwares have more calibration commands therefore
hardcoding the noise gain/reset commands no longer works. It is
supposed to use the next index after the newest calibration type
support. Read the command index of the TLV section if available.
- We have two nodes connected and synchronized (local counters on both sides
are 0).
- We take secondary down and recreate it.
- Primary connects to it and starts synchronization (but local counters are
still 0).
- We switch the roles.
- Synchronization restarts but data is synchronized now from new primary
(because local counters are 0) that doesn't have new data yet.
This fix this issue we bump local counter on primary when we discover that
connected secondary was recreated and has no data yet.

compiler. ;)
