nvme: Don't active memory space until all BARs are configured
In the current current behavior the 2nd and 3rd BARs can be activated
when they're configured with address zero. This change defers the
activation of all BARs until after they've all been configured with an
address.
This enables FreeBSD on Google Compute Engine C4-LSSD Machines.

style.9: Encourage style changes when doing significant modifications
The rule of allowing style changes when about half or more of a file (or
group of files), coupled with the advice of avoiding stylistic changes,
could be interpreted as forbidding most style changes, even in heavily
modified functions.
In order to rule out that interpretation and ease transition towards our
prescribed style:
1. Clarify that avoiding stylistic changes concerns only "standalone"
ones.
2. Actually encourage changing the style, and extend the cases where it
is explicitly allowed to do so to any single logical unit as little
as a function, keeping the existing "about half" of modified code as
a rule of thumb.
When point 2 above applies, encourage to commit pure style changes
separately, and to add style-only commits to '.git-blame-ignore-revs'.

llvm-cxxfilt: Install as c++filt only with LLVM_BINUTILS
When building WITHOUT_LLVM_BINUTILS /usr/bin/c++filt is the one from
ELF Tool Chain.

splice: optionally limit worker queues
Add a new tunable/sysctl (kern.ipc.splice.num_wq) which can be used
to limit the number of splice worker queues as a way to limit
splice cpu use.
The default (-1) keeps the current behavior of running one worker
for each core in the system. An administrator can set it to 0 (either
via tunable, or before the first splice call via sysctl) to
effectively disable splice, or some number smaller than the number of
cores to limit splice thread use.
