bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

fix reversed comment

branches: 1.7.4;
add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories. Avoids having
to add a CPPFLAGS (or several) to pretty much every component
Makefile.

Leave compat headers around in the old locations.

The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

Add a COMMENT describing what each component roughly does.

"make describe" prints the comment.

Requested/inspired by Vincent Schwarzer on rumpkernel-users

branches: 1.4.6;
rename component.c -> zfs_component.c

branches: 1.3.4; 1.3.6; 1.3.16; 1.3.20;
autocreate /dev/zfs. requested by riz

branches: 1.2.2;
Since "physmem" is largely unused except for zfs wanting to know
if it has enough memory available, just pick a number which makes
zfs happy.

We *could* use a MIN() of available host mem and rump_memlimit,
though ...

branches: 1.1.2;
Add support for compiling ZFS and Solaris modules as RUMP libraries. Add
some locking and rumpcopy primitives and refactor module building Makefiles
to work with both RUMP and kernel modules. This is first part of adding
support for regular test of zfs on NetBSD to hunt some bugs and make it
stable.

Ok by pooka@.
