Some hypervisor calls, such as H_SEND_LOGICAL_LAN, take more arguments than
are traditionally passed in registers.  The HCALL ABI will accept these
arguments in r11 and r12.  With ELFv2 ABI, these arguments are 2
double-words lower than ELFv1 ABI, as two double-words in the stack frame
are no longer used, and therefore removed from the frame.  Fix the offsets
for loading the registers for the HCALL.  This fixes the phyp_llan driver
with ELFv2 kernel.

During processing we maintain symbol offsets in the 64-bit s_so array,
and when writing the archive convert to 32-bit if no offsets are greater
than 4GB.  However, this was somewhat inefficient as we looped over the
array twice: first, converting to big endian and second, writing each
32-bit value one at a time (and incorrectly so on big-endian platforms).

Instead, when writing a 32-bit archive shuffle convert symbol data to
big endian (as required by the ar format) and shuffle to the beginning
of the allocation at the same time.

Also correct emission of the symbol count on big endian platforms.

Further changes are planned, but this should fix powerpc64.

worked right for white interiors and black borders was used).  Advertise
this by changing the default colors to a red interior and a white
border (the same as the kernel default).  Add undocumented env variables
for changing these colors.  Also change to the larger and better-shaped
16x10 cursor sometimes used in the kernel.  The kernel choice is
fancier, but libvgl is closer to supporting the larger cursors needed
in newer modes.

The (n)and-or logic for the cursor doesn't work right for more than 2
colors.  The (n)and part only masks out all color bits for the pixel
under the cursor when all bits are set in the And mask.  With more
complicated logic, the non-masked bits could be used to implement
translucent cursors, but they actually just gave strange colors
(especially in packed and planar modes where the bits are indirect
through 1 or 2 palettes so it is hard to predict the final color).
They also gave a bug for writing pixels under the cursor.  The
non-masked bits under the cursor were not combined in this case.

Drop support for combining with bits under the cursor by making any nonzero
value in the And mask mean all bits set.

Convert the Or mask (which is represented as a half-initialized 256-color
bitmap) to a fully initialized bitmap with the correct number of colors.
The 256-color representation must be as in 3:3:2 direct mode iff the final
bitmap has more than 256 colors.  The conversion of colors is not very
efficient, so convert at initialization time.

This commit adds new if_alloc_domain() and if_alloc_dev() methods to
allocate ifnets.  When called with a domain on a NUMA machine,
ifalloc_domain() will record the NUMA domain in the ifnet, and it will
allocate the ifnet struct from memory which is local to that NUMA
node.  Similarly, if_alloc_dev() is a wrapper for if_alloc_domain
which uses a driver supplied device_t to call ifalloc_domain() with
the appropriate domain.

Note that the new if_numa_domain field fits in an alignment pad in
struct ifnet, and so does not alter the size of the structure.

There's no reason why a special case needs to be added specifically for amd64,
arm, and i386, as the code is written in machine architecture agnostic C/C++.

This will make it possible for all supporting clang architectures to produce
runtime coverage with `--coverage`.

r345708 worked for the base system, but unfortunately, caused a lot of
disruption for third-party packages that relied on C++, since bsd.sys.mk is
used by applications outside the base system. The defaults picked didn't match
the compiler's defaults and broke some builds that didn't specify a standard,
as well as some that overrode the value by setting `-std=gnu++14` (for
example) manually.

This change takes a more relaxed approach to appending `-std=${CXXSTD}` to
CXXFLAGS, by only doing so when the value is specified, as opposed to
overriding the standard set by an end-user. This avoids the need for having
to bake NOP default into bsd.sys.mk for supported compiler-toolchain
versions.

In order to make this change possible, add CXXSTD to Makefile snippets which
relied on the default value (c++11) added in r345708.

This change allows the user to once again override the C++ standard, restoring
high-level pre-r345708 behavior.

This also unbreaks building lib/ofed/libibnetdisc/Makefile with a non-C++11
capable compiler, e.g., g++ 4.2.1, as the library supported being built with
older C++ standards.

There's no reason we can't setup the console first thing after the
arch flags are setup. We set it undconditionally to efi. This is a
good default, and will get us error messages to at least the efi
console no matter what. This will also prime the pump so that as other
variables are set, they will take effect and the console will be
correct as soon as those env vars are set. Also remove the redundant
setting of the console to efi when we know the console is efi.
