Currently the IO-APIC is fully initialized after PCI initialization
resulting in the IO-APIC not being initialized on systems without a
PCI bus (i.e. Hyper-V Gen2 VMs). This change moves IO-APIC
initialization to occur during early init, deferring PCI interrupt
enumeration and routing until after PCI initialization has been
completed.

* macOS awk doesn't support strftime, so try to find a working

* _haiku_build_{open,openat,fcntl} are declared and defined with
different prototypes (variadic vs non-variadic). This is bad
on its own, but it "happens to" work on most platforms since
variadic parameters are usually passed in registers, same as other
arguments. On arm64 macOS, variadic parameters are always passed
on the stack, so you get weird and confusing bugs when using
these functions.

The SMP_MAX_CPUS * 4 fixed pool size apparently goes all the way
back to NewOS, which supported only 4 CPUs max. As ours is now
64, this means the fixed pool size was very large even on systems
with only a few cores. So, instead, allocate 4 messages per CPU
(though often more, due to rounding up to the page size; e.g.
on x86_64, 1 page fits 56 smp_msgs.)
Also, put them a dedicated area, to keep them a bit more segmented
from the kernel heap, in case of problems.
Since the kernel is built with -ffreestanding, and thus -fno-builtin,
the compiler ignores the function names and doesn't perform optimizations
(e.g. inlining for small values) that it otherwise could. So, here,
we add a string.h that supplements the default, and uses #define to
reinstate the builtins, and thus the optimizations.
Linux and FreeBSD at least apparently do the same. A quick compile
benchmark in a VM doesn't show much difference, maybe a slight
decrease in sys time.

According to the Bluetooth Core Specification, Vol. 4, Part E, 7.7.2, for HCI_Inquiry_Result a struct of arrays is returned, and not
an array of structs. The previous code parsed it as if it is an array of
structs, so fixed that. Refactored MessageReceived so that that its
easier to implement HCI_EVENT_EXTENDED_INQUIRY_RESULT and
HCI_EVENT_INQUIRY_RESULT_WITH_RSSI going forward.

&fSuperBlock+N advances by N*sizeof(btrfs_super_block) bytes,
not N bytes. The correct form is (uint8*)&fSuperBlock+N which
advances by exactly N bytes past the start of the superblock,
correctly skipping the checksum field.

I checked all invocations of GetBit; as far as I can tell,
only the two adjusted here in smp.cpp are done while the Set
may be concurrently modified, and even then I don't know
that they really need to be atomics, anyway.
This allows read spinlocks to be used in check_for_message
and return_free_message.
On a 4-core VM, there don't seem to often be concurrent readers
(a counter I setup got only about 400-500 hits for booting up
and starting a web browser, at most.) But on bare metal (i3,
2 cores x 2 hyperthreads) we get it a lot more: 30,000+ times
during boot alone.
Kernel map invalidation (with a hack to invalidate all every time)
across boot-to-desktop takes a cumulative ~68.0ms before this change,
and ~61.0ms after, on the bare metal system. (On the VM it's also lower
after this change.)
Presumably on systems with more CPUs it will get hit even more
often still. So this optimization seems worth it.
Like the other race, this becomes an issue once
PCID is supported. If a user thread initiates a
TLB flush and is interrupted, it may have a new
PCID next time, so arch_cpu_invalidate_tlb_list
returns without invalidating any TLB entries...
