Make dynamic link of libiconv from ports work again.
The symbols of libiconv from ports were changed to
have prefixed.
Since we have iconv in our libc these days, we don't
need it on 10.X and later. However, 9.X still need
this.
Set watchdog timer parameters only when they really need to be changed.
In other cases just restart the timer with single Reset command instead
of two (Set and Reset).
From one side this visually reduces amount of CPU time burned in tight
loop waiting while some slow BMC configures its watchdog hardware, that
seems to be much more complicated task then just resetting the timer.
From another side on some BMCs those slow Set commands sometimes tend to
timeout, that leads to noisy log messages and even more CPU time burned,
so avoiding them can provide even bigger bonuses.
MFC r297232: Unify ignoring EEXIST from zvol_create_minor().
This fixes creation of zvol devices for snapshots during zfs receive,
that previously failed with "ZFS WARNING: Unable to create ZVOL" message.
This solution is not perfect, but IMHO better then it was before.
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE. The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl. M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.
Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.
Update netmap_get_mbuf to not pass M_NOFREE to m_getcl. It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.

During the update process in sa_modify_attrs(), the sizes of existing

a variably-sized SA was being replaced neglected to increment the index
into sa_lengths[], so subsequent variable-length SAs would be rewritten
with the wrong length. This patch adds the missing increment operation
so all variably-sized SA entries are stored with their correct lengths.
Another problem was that index into attr_desc[] was increased even when
an attribute was removed. If that attribute was not the last attribute,
then the last attribute was lost.
