Add documentation and symlinks for OF_getprop_alloc_multi
and OF_getencprop_alloc_multi functions.
Also while here fix copy-pasted .Dt value and add one more
failure condition for OF_getencprop_alloc.
r332341 introduced OF_getencprop_alloc_multi that should be used
instead of OF_getencprop_alloc to get multi-cell properties.
Fix example to reflect this change.
Normally pf rules are expected to do one of two things: pass the traffic or
block it. Blocking can be silent - "drop", or loud - "return", "return-rst",
"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.
Allow users to configure this behaviour too, so that pf returns an error packet
in these cases.

This makes it possible, through src.conf(5) settings, to select which
LLVM targets you want to build during buildworld. The current list is:
* (WITH|WITHOUT)_LLVM_TARGET_AARCH64
* (WITH|WITHOUT)_LLVM_TARGET_ARM
* (WITH|WITHOUT)_LLVM_TARGET_MIPS
* (WITH|WITHOUT)_LLVM_TARGET_POWERPC
* (WITH|WITHOUT)_LLVM_TARGET_SPARC
* (WITH|WITHOUT)_LLVM_TARGET_X86
To not influence anything right now, all of these are on by default, in
situations where clang is enabled.
Selectively turning a few targets off manually should work. Turning on
only one target should work too, even if that target does not correspond
to the build architecture. (In that case, LLVM_NATIVE_ARCH will not be
defined, and you can only use the resulting clang executable for
cross-compiling.)
I performed a few measurements on one of the FreeBSD.org reference
machines, building clang from scratch, with all targets enabled, and
with only the x86 target enabled. The latter was ~12% faster in real
time (on a 32-core box), and ~14% faster in user time. For a full
buildworld the difference will probably be less pronounced, though.

This works similar to WITH_SYSTEM_COMPILER added in r300354. It only
supports lld via WITH_LLD_BOOTSTRAP.
When both SYSTEM_COMPILER and SYSTEM_LINKER logic passes then libclang
will not build in cross-tools. If either check fails though then
libclang is built.
The .info is reworked to notify when libclang will be built since if
either clang or lld needs to be rebuilt, but not the other, the
notification can lead to confusion on why "clang is building".
-fuse-ld= is not used with this method so some combinations of compiler
and linker are expected to fail.
A new 'make test-system-linker' target is added to see the logic results.
Makefile.inc1:
CROSS_BINUTILS_PREFIX support had to be moved higher up so that XLD
could be set and MK_LLD_BOOTSTRAP disabled before checking SYSTEM_LINKER
logic as done with SYSTEM_COMPILER. This also required moving where
bsd.linker.mk was read since XLD needs to be set before parsing it. This
creates a situation where src.opts.mk can not test LINKER_FEATURES or
add LLD_BOOTSTAP to BROKEN_OPTIONS.

Most kernel memory that is allocated after boot does not need to be
executable. There are a few exceptions. For example, kernel modules
do need executable memory, but they don't use UMA or malloc(9). The
BPF JIT compiler also needs executable memory and did use malloc(9)
until r317072.
(Note that a side effect of r316767 was that the "small allocation"
path in UMA on amd64 already returned non-executable memory. This
meant that some calls to malloc(9) or the UMA zone(9) allocator could
return executable memory, while others could return non-executable
memory. This change makes the behavior consistent.)
This change makes malloc(9) return non-executable memory unless the new
M_EXEC flag is specified. After this change, the UMA zone(9) allocator
will always return non-executable memory, and a KASSERT will catch
attempts to use the M_EXEC flag to allocate executable memory using
uma_zalloc() or its variants.
Allocations that do need executable memory have various choices. They
may use the M_EXEC flag to malloc(9), or they may use a different VM
interfact to obtain executable pages.
Now that malloc(9) again allows executable allocations, this change also
reverts most of r317072.

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.

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.
