Exclude PCI-PCI bridge windows from acpidmar(4) with match based on header type
This introduces acpipci_domain_to_seg() to translate OpenBSD's pci domains
to ACPI segments for rare multi-segment machines (qemu)

httpd: don't send the fastcgi param struct over imsg
Send one imsg per param with a small fixed header (fastcgi_param_imsg)
followed by the name and value bytes, and read it back with imsg_get_ibuf()
and ibuf_get_string(). The struct now uses dynamic buffer instead of fixed,
and the value limit is raised to 8192. Parse order is now preserved end-to-end
instead of being reversed twice. This follows the config order.

Unlock CRYPTO_LOCK_UI on ui_open_session() failure
Both ui_open_session() implementations, open_console() in ui_openssl.c
in base, and the one in ui_openssl_win.c in portable, grab the lock of
type CRYPTO_LOCK_UI before doing anything else.
The only internal (and, as far as I can tell, the only existing) caller,
UI_process(), returns immediately on failure. The calling thread thus
keeps holding the lock and the next call to UI_process() will block
indefinitely. Fix this by using the common exit path, which calls
ui_close_session() aka close_console(), both implementations of which
release the lock.
Thanks to Kartik (@sage-mode-hunter) who proposed an alternative fix for
ui_openssl_win.c, which we would have to apply to ui_openssl.c as well.
Matches OpenSSL behavior since PR #2037

relayd: correct edh relayd.conf.5
The previous wording implied that omitting "params" defaulted to auto.
"edh" alone enables EDH in auto mode, while leaving the directive out
keeps EDH disabled (equivalent to no edh / edh params none).
httpd: add custom HTTP header support
Allow httpd.conf to set/add/remove custom HTTP response headers or Suppress
existing ones. This enables httpd to add security headers, custom metadata,
or remove unwanted headers without modifying app/fastcgi code.
Three new directives are added:
header option
Manipulate HTTP response headers. Multiple header statements may
be specified. Valid options are:
set name value [always]
Set a custom HTTP response header with the specified name
and value. If a header with the same name is already
present in the response, its value will be replaced. The
header is added to successful responses (2xx and 3xx
status codes) by default.

Kill the uvm_pmalloc mechanism. This never really worked, at least until
kirill@ fixed some page number/address confusement. But it can't really
work since pages freed by the pagedaemon are likely going to be grabbed
by other consumers before we issue a wakeup through the uvm_pmalloc
mechanism. At this point the consensus is that it adds complexity to the
pagedaemon that stands in the way of progress.

vmd(8): guard firmware config system state with a mutex.
While vmd is not yet SMP, if multiple VCPUs emulate io to the Qemu
firmware config registers simultaneously, they will race in mutating
and observing state.

vmd(8): reject GPAs in holes during gpa translation.
vmd independentaly allocates guest memory in a series of ranges,
mirroring the physical memory layout for the guest. The GPA translation
in find_gap_range() incorrectly selects a memory range if the GPA
is in a hole between two guest memory ranges. Make the initial check
that the GPA falls within the bounds of a known memory range instead
of just prior to the end.

vmd(8): guard virtio entropy device register io with a mutex.
While vmd isn't yet SMP capable, in the event multiple VCPU thread
exist they may interleave in emulation of register access of the
virtio entropy device because it's currently emulated in the vm
process.

vmd(8): initialize the direct-boot argument page.
In vmd's ELF loader, the boot args page is copied into guest memory
from the stack without complete initialization. Initialize to zero
to prevent leaking stack values into guest memory.

Reject invalid payload sizes at vmd(8) control boundary.
When we introduced agressive parsing and santization of imsg objects,
it introduced the ability for a control socket client to force vmd
to exit via fatal() calls. A simple solution is to validate just
the size of the object at the control process boundary as that's
the primary logic for triggering fatal() calls. This may need a
greater redesign but that would require inspecting all imsg
deseralization call points. For now, the author's proposal is fine.

Add support for the RISC-V Advanced Interrupt Architecture. This adds
new imsic(4) and aplic(4) drivers for the Incoming MSI Controller and
Advanced Platform-Level Interrupt Controller and supports the standard
configuration where both are presents and imsic(4) functions as the
top-level interrupt controller and aplic(4) forwarding classic interrupt
lines as MSIs to imsic(4). Tested on QEMU and Spacemit K3.
