No need for "foo$(printf "\t")", $'\t' is both more readable and still
functional.

vfs_cache_lookup() has already done the appropriate VEXEC check, therefore
we must not re-check in VOP_CACHEDLOOKUP.

This fixes O_SEARCH semantics on tmpfs and removes a redundant descent into
VOP_ACCESS() in the common case.

I originally applied a fix in #11539 to fix a parent's child references
when a gang ABD is free'd. However, I did not take into account
abd_gang_add_gang(). We still need to make sure to update the child
references in this function as well. In order to resolve this I removed
decreasing the gang ABD's size in abd_free_gang() as well as moved back
the original placeent of zfs_refcount_remove_many() in abd_free().

The current uname is branch-cXXXX-gHASH

Three changes to make uname more useful.
1. Move from using git rev-list --count to git rev-lis --count --first-parent
   since that gives a better, incrementing number.
2. Report this count as 'nXXXXX' rather than 'cXXXXX' because c is part of
   a hash and we've changed the sematnics of XXXXX
3. Remove g to make HASH cut and pastable.

Durting review, #1 & #3 had the largest consensus. There was a diversity of
opinion on #2, but on the whole it was positive so I'll acknowledge the dissent,
but move forward with something seems to have support since the dissent was all
about what letter to use where I chose 'n'.

newer controller have a sparce bus space that can be figured
out by probing the HW.  This gives the starting bus number.
When reading the PCI config. space behind the VMD controller,
the offset of the starting bus needs to be subtracted from
the bus being read.

Fixed a bug in which in which not all of the devices
directly attached to the VMD controller would be probed.
On my initial test HW, a switch was found at bus 0, slot 0
and function 0.  All of the NVME drives were behind that
switch.  Now scan for all slots and functions attached to
bus 0.  If a something was found then run attach after the
scan.  On detach also go through all slots and functions
on bus 0.

Move software iSCSI tunables/sysctls into kern.icl.soft subtree.
Replace several hardcoded length constants there with variables.

While there, stretch the limits to better match Linux' open-iscsi
and our own initiator with new MAXPHYS of 1MB.  Our CTL target is
also optimized for up to 1MB I/Os, so there is also a match now.
For Windows 10 and VMware 6.7 initiators at default settings it
should make no change, since previous limits were sufficient there.

Tests of QD1 1MB writes from FreeBSD over 10GigE link show throughput
increase by 29% on idle connection and 132% with concurrent QD8 reads.
