This commit brings back the driver from FreeBSD commit
f187d6dfbf plus subsequent fixes from
upstream.
Relative to upstream this commit includes a few other small fixes such
as additional INET and INET6 #ifdef's, #include cleanups, and updates
for recent API changes in main.

This code was originally written under the assumption that the ISA
string would only contain single-letter extensions. The RISC-V
specification has extended its description of the format quite a bit,
allowing for much longer ISA strings containing multi-letter extension
names.
Newer versions of QEMU (7.1.0) will append to the riscv,isa property
indicating the presence of multi-letter standard extensions such as
Zfencei. This triggers a KASSERT about the expected length of the
string, preventing boot.
Increase the size of the isa array significantly, and teach the code
to parse (skip over) multi-letter extensions, and optional extension
version numbers. We currently ignore them completely, but this will
change in the future as we start supporting supervisor-level extensions.

Add a minimal implementation of cpu_ptrace() for arm64. It is only used to
get/set VFP registers for 32bits binaries, as it is apparently what we use
there, instead of the MI PT_GETFPREGS/PT_SETFPREGS.

When building a kernel without FDT these modules don't build. As they
depend on FDT and don't work with ACPI disable them.

Add hostfs for the Linux environment. We can't use the userboot one
that's kinda similar because the Linux system calls we have in kboot are
not quite POSIX compliant (Linux takes care of providing the POSIX
interface in libc), so we have to cope with a number of quirks in that
area.

The fixups needed vary somewhat by architecture, so move the FDT fixup
to be per-arch. Rename the fdt_linux_fixup() routine to be
fdt_arch_fixup() and expect all architecutres to fix things up as
needed.

Linux reads MISC_FEATURES_ENABLES to manage the CPUID faulting feature
(undocumented in the Intel SDM, but documented in 323850-004 (Intel
Virtualization Technology FlexMigration Application Note). Since bhyve
doesn't emulate this feature, we always return 0. Neither does bhyve
support the MONITOR/MWAIT fault bit also in this MSR (which is
documented in the sdm), so always return 0.

Something else may have set errno, breaking the post-getline() logic
that tries to detect the getline() error. This was initially noted in
a jail on a system that has HPET, in a jail that does not expose
/dev/hpet0 -- we see an earlier error in libc's vdso bits.
Fixes: 5c053aa3c5 ("split: switch to getline() [...]")
MAX_APIC_ID must be at least twice MAXCPU. Increase it to 0x800 so that
it is possible to set MAXCPU to 512 or 1024 in a custom kernel config
file.
Note that increasing this limit does not itself cause any allocations
to be larger; it just allows madt_parse_cpu() to process higher APIC
IDs.
APIC IDs may be sparse and so we can waste memory. This is independent
of this change, but becomes more of an issue as the maximum APIC ID
grows. This should be addressed with future work.

The cpu_dcache_wb_range function is an expensive function that is
unneeded in ddb. It is used when the cache needs to be written to RAM,
e.g. when working with a non-cache coherent device.
Remove it as cpu_icache_sync_range already has the needed d-cache
handling to ensure any changed memory is visible to the i-cache.
