libc: INTERPOS_SYS macro for interposed syscalls

greatly simplify calling functions in the interposing table.

libsys: add a libsys.h
This declares an API for libsys which currently consists of
__sys_<foo>() declarations for system call stubs and function pointer
typedefs of the form __sys_<foo>_t. The vast majority of the
implementation resides in a generated _libsys.h which ensures that all
system call stub declarations match syscalls.master.

wg: Use ENETUNREACH when transmitting to a non-existent peer
The old errno value used is specifically for Capsicum and shouldn't be
co-opted in this way. It has special handling in the generic syscall
layer (see syscallret()). OpenBSD returns ENETUNREACH in this case;
let's do the same thing.

pfilctl: fix 'pfilctl hooks' when nothing is connected
The 'hooks' command actually worked accidentially until now. It used
PFILIOC_LISTHEADS to determine current number of hooks. This worked when
at least one head had a hook connected to it.

tzsetup: be explicit about *timezone* abbreviation
During the install process tzsetup asks a question like
Does the abbreviation `EDT' look reasonable?
The installer asks lots of questions, some that relate to the previous
screen or topic and some that do not. A new user installed FreeBSD for
the first time and was confused by this question, not realizing that it
was asking whether the abbreviation is correct for the selected
timezone.

x86/xen: fix accounted interrupt time
The current addition to the interrupt nesting level in
xen_arch_intr_handle_upcall() needs to be compensated in
xen_intr_handle_upcall(), otherwise interrupts dispatched by the upcall handler
end up seeing a td_intr_nesting_level of 2 or more, which makes them assume
there's been an interrupt nesting.
Such extra interrupt nesting count lead to statclock() reporting idle time as
interrupt, as the call from interrupt context will always be seen as a nested
one (td->td_intr_nesting_level >= 2) due to the nesting count increase done by
both xen_arch_intr_handle_upcall() and intr_execute_handlers().
Fix this by adjusting the nested interrupt count before dispatching interrupts
from xen_intr_handle_upcall().

This commit also added a new command line option "-A' that

loader: lua: assume late ACPI detection if the feature isn't enabled
While we're here, enable the feature in the places we detect ACPI. This
lets us side-step the existing issues and provide a path forward for
folks upgrading from previous releases that haven't updated their ESP
yet.
Let's also fix core.setACPI: the hint already indicates that the
user's disabled it more consistently than loader.acpi_disabled_by_user.
Even more, the latter is wrong because we set it by default if we did
not detect ACPI. The ACPI hint remains even when we're setting defaults
because ACPI loaded into the kernel will make some noise if it's not
hinted off, even when we didn't detect it.
imp notes that this will result in some relatively harmless noise on
platforms that don't support ACPI but aren't using the UEFI loader, as
we would enable the ACPI module for loading on them and then loader
would not be able to find it. These are non-fatal, but should probably
be fixed by just declaring support for EARLY_ACPI in those loaders since

pmbr: Only load the first 545k rather than error out
It would be nice to have larger boot partitions for ESPs to live in one
day. It's trivial to carve out 5M 10M or 200M when provisioning, but
logistical issues may make it hard to do it after the fact. So only warn
when the partition is > 545k. If we ever grow the boot loader larger
than that, then it will be responsible for loading the rest anyway.

loader: fix EFI ACPI detection
lua was previously unable to determine ACPI presence because this
probing was postponed until the final loading and execution of the
kernel.
This patch resolves that by detecting ACPI early (similar to
the order of operations in the legacy i386 loader).

stand: bandaide for acpi
Old binaries do not set acpi.rsdp early enough. So when we boot with an
older loader.efi from an ESP that's not been updated, we assume there's
no ACPI on this system. This is unwise. Put a band-aide on this until we
can implement a proper 'feature' variable that the binary reports so we
can do conditionals for things like this in the future.
This is at best a rapid-response stop-gap.
