bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
	GCC_NO_warning
to
	CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

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

Mostly merge changes from HEAD upto 20200411

Elide function pointer cast errors

Sync with HEAD

Bump default value of WARNS for modules from 3 to 5, and
explicitly set WARNS for modules that fail with WARNS=5.

Also, turn on -Wno-missing-noreturn for clang for some files.

At the moment, among ~ 360 modules,
- 2 (lua and zfs) need WARNS=0
- 1 (solaris) needs WARNS=1
- 136 need WARNS=3 (mostly due to sign-compare)
- 4 need WARNS=4
- others can be compiled with WARNS=5

Discussed on tech-kern.

Sync with HEAD

Rework the changes to DTRACE/ZFS files that were fixing Clang/LLVM build

Rever changes to upstream files and replace them with additional -Wno-
compiler argument flags.

Tested with base LLVM.

Replace HAVE_GCC with ACTIVE_CC == gcc checks

Kernel modules build with GCC and Clang/LLVM.

Requested by <joerg>

Restrict -Wno-unused-but-set-variable in sys/modules/dtrace/dtrace to GCC

Clang/LLVM does not recognize it.

This is a step forward functional MKLLVM=yes HAVE_LLVM=yes build.

Swap conditions HAVE_LLVM -> HAVE_GCC

Restrict -Wno-discarded-qualifiers in sys/modules/dtrace/* to GCC

Clang/LLVM does not recognize it.

This is a step forward functional MKLLVM=yes HAVE_LLVM=yes build.

merge a new version of the CDDL dtrace and ZFS code.
this changes the upstream vendor from OpenSolaris to FreeBSD,
and this version is based on FreeBSD svn r315983.

in addition to the 10 years of improvements from upstream,
this version also has these NetBSD-specific enhancements:
 - dtrace FBT probes can now be placed in kernel modules.
 - ZFS now supports mmap().
