Make __CTASSERT static assert again

Today GCC/Clang allow to specify typedef char[] with the dynamic VLA
property (as introduced in C99). This means that __CTASSERT(), when
misused with run-time semantics, was a dummy check generating either
1 or -1 size of typedef char[].

It was caught in runtime by kUBSan as -1 is size of VLA with unspecified
semantics in runtime (Undefined Behavior).

Use bit-field to enforce compile-time constant.

This approach has been inspired by the Perl variation of static_assert().

Initialise the sometvs array of struct timeval that is to be used to
validate that utimes() cannot update the times of a file on a read only
filesystem.  The values are never actually used, but since
src/sys/kern/vfs_syscalls.c 1.535
they are validated for sanity, and the syscall returns EINVAL if the
values passed are invalid (tv_usec <0 or >= 1000000).  If that happens
we don't get as far as the test which produces the EROFS that is expected
from this test (these tests - one for each filesystem type).

So, init the timeval structs (just to 0, the values will still not be
used) so that the EINVAL doesn't bite us before we're eaten by the EROFS
which is the way we're supposed to die.

If the syscall API args were labelled as "const" the compiler probably
would have caught the use of uninit'd vars and complained much sooner.

l2tp(4): avoid having struct ifqueue directly in a percpu storage.

percpu(9) has a certain memory storage for each CPU and provides it by the piece
to users.  If the storages went short, percpu(9) enlarges them by allocating new
larger memory areas, replacing old ones with them and destroying the old ones.
A percpu storage referenced by a pointer gotten via percpu_getref can be
destroyed by the mechanism after a running thread sleeps even if percpu_putref
has not been called.

Tx processing of l2tp(4) uses normally involves sleepable operations so we
must avoid dereferencing a percpu data (struct ifqueue) after executing Tx
processing.  Address this situation by having just a pointer to the data in

Avoid having a rtcache directly in a percpu storage

percpu(9) has a certain memory storage for each CPU and provides it by the piece
to users.  If the storages went short, percpu(9) enlarges them by allocating new
larger memory areas, replacing old ones with them and destroying the old ones.
A percpu storage referenced by a pointer gotten via percpu_getref can be
destroyed by the mechanism after a running thread sleeps even if percpu_putref
has not been called.

Using rtcache, i.e., packet processing, typically involves sleepable operations
such as rwlock so we must avoid dereferencing a rtcache that is directly stored
in a percpu storage during packet processing.  Address this situation by having
just a pointer to a rtcache in a percpu storage instead.

Create the character device for spiflash, in addition to the block device.
This is needed for getdiskrawname() to DTRT (for installboot(8)).

Add support for additional install step directives to enable using
installboot(8) to write u-boot images to SPI NOR and other types of
raw flash devices: input-block-size, input-pad-size, output-size, and
output-block-size.

Add the ability to create aliases for install objects, useful for when
e.g. sdmmc and emmc share the same steps.

Add multiboot 2 support to x86 bootloaders

multiboot 2 is required to boot Xen on an EFI system.

This also require a kernel patch for properly discovering
the ACPI RSDP, which is available after 20190912, in
src/sys/arch/x86/acpi/acpi_machdep.c 1.26-1.28

There are a few missing bit in this multiboot 2 implementation
(which are unused by Xen):
- Header tags Address, Freambuffer, and Relocatable are ignored
- Tags APM and Network are not provided
- Tags ACPI old and ACP new are only provided for ACPI boot
- Tag boot device does not provides the subpart (BSD disklabel partition)

Notes:
- multiboot2 is disabled in dosboot, otherwise the binary
  gets too big and build fails.
- in src/sys/arch/i386/stand/efiboot, consinit() is renamed
  as efi_consinit() to avoid prototype conflicts in src/sys/sys/systm.h

Remove debug define.

It remained there unseen because it was misspelled!

Remove obsoeolete BUGS note that UEFI bootloader does not support multiboot

Add new multiboot2.h header.

Attempt to obtain ACPI RSDP from the hypervisor for Xen PV
There are three possible way of obtaining the ACPI RSDP

- From Extended BIOS Data Area (EBDA) when kernel or Xen was booted from
  BIOS bootstrap
- From EFI SystemTable when kernel is booted from EFI bootstrap
- When Xen is booted from EFI bootstrap, EBDA is not mapped, and EFI
  SystemTable is not passed to the kernel. The only way to go is to
  obtain ACPI RSDP trhough an hypercall.

Note: EFI bootstrap support for booting Xen has not yet been committed.

Cast physical addresses via uintptr_t to ACPI_PHYSICAL_ADDRESS to deal
with all size variants of the types used here in different builds.
