linux_vdso.so provides the vdso for the linuxulator's amd64 target and
is mapped into a Linux binary's address space. Thus it should be a
Linux-style .so, which has the ELF OS/ABI unset.
It turns out that ELF Tool Chain elfcopy/objcopy also has a bug where
the OS/ABI field is unset, regardless of the specified --output-target,
so this change is a no-op with the default in-tree toolchain. This is a
real fix when using external binutils, and the ELF Tool Chain bug will
be fixed in the future.

This eliminates the difficult to follow mapping of a string list. It
moves numbers from "#define" into (more) debuggable enums. More
generally, it follows the trend of moving more data into a more central
mechanism.
The help output is a little worse: " " is not rendered well, and there
are duplicate entries, but that will be fixed in a followup.
It was needed only for ia64 where it was implemented as a call to
bswapXX, which was always a real function. htobeXX with a constant
argument is calculated at compile-time everywhere else.

To recap the problem: with a black-on-white xterm, the menu draws terribly.
Ideally, we would try our best for a white-on-black context for the menu
since graphics and whatnot might not be tested for other setups and there's
no reasonable way to sample the terminal at this point for the used color
scheme.
This commit attempts to address that further in two ways:
- Instead of issuing CSI bg/fg resets (CSI 39m and CSI 49m respectively for
"default"), issue CSI bg/fg escape sequences for our expected color scheme
- Reset to *our* default color scheme before we even attempt to load the
local module, so that we personally don't have any earlier text with the
console default color scheme.

The BPF code was creating a compiled filter in the common filter-creation
path. However, BPF only uses compiled filters in the read direction.
When creating a write filter, the common filter-creation code was
creating an unneeded write filter and leaking the memory used for that.

devd predates service in the system. Modernize usage to use service to
start/stop things in reaction to events rather than calling the rc
file directly.
This was pointed out in my talk at BSDcan as well as indirectly
referrred to as a barrier to entry for OpenRC in that working group.
Lack of functioning link and activity LEDs on devices without an EEPROM
is expected (not a bug). Quoting the EVB-LAN7850 User's Guide:
When configured with the default internal register settings, the
Ethernet Link status LEDs are not enabled. To enable Ethernet Link
status LEDs, enable the EEPROM.
This is an artifact of the different ways in which the evaluation board
can be used. End-user USB-Ethernet adapters using the Microchip LAN78XX
or LAN7515 controllers should use an EEPROM or have OTP configuration,
if their product configuration does not match the boot default register
configuration.

The size limits came from a flawed understanding of dump records.
The real issue was that dump was bogusly interpreting c_count
sometimes. r334978 fixes that.
We shouldn't count the bytes set in c_addr for TS_CLRI and TS_BITS
nodes. Those block overload c_count to communicate how many blocks
follow, not now many c_addr spaces are used. Dump would dump core
(now) because memory layout moved around and we'd access elements past
the end to make a count.

lan78xx_eeprom_read just checked for EEPROM presence then called
lan78xx_eeprom_read_raw if present, and had only one caller. Introduce
lan78xx_eeprom_present to check for EEPROM presence, and use it in the
one place it is needed.
This is used by r334964, which was accidentally committed out-of-order
from my work tree.

Add some asserts that prevents the overflows of c_addr. This can't
happen, absent bugs. However, certain large filesystems can cause
problems. These have been prevented by r334968, but a solution
is needed. These asserts will help assure that solution is correct.

There were a couple of cases in newnfs_request() that it assumed that it
was an NFSv4.1 mount with a session. This should always be the case when
a Sequence operation is in the reply or the server replies NFSERR_BADSESSION.
However, if a server was broken and sent an erroneous reply, these safety
belt checks should avoid trouble.
The one check required a small tweak to nfsmnt_mdssession() so that it
returns NULL when there is no session instead of the offset of the field
in the structure (0x8 for i386).
This patch should have no effect on normal operation of the client.
Found by inspection during pNFS server development.

Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

Base gcc fails to compile sys/dev/drm2/i915/intel_display.c for i386,
with the following -Werror warnings:
cc1: warnings being treated as errors
/usr/src/sys/dev/drm2/i915/intel_display.c:8884: warning:
initialization from incompatible pointer type
This is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36432, which
incorrectly interprets the [] as a flexible array member.
Because base gcc does not have a -W flag to suppress this particular
warning, it requires a rather ugly cast. To not influence any other
compiler, put it in a #if/#endif block.
