Summary:
This adds required IPQ4018/IPQ4019 SoC support to boot.
It also includes support for disabling the ARMv7 hardware
breakpoint / debug stuff at compile time as this is
required for the IPQ SoCs, and printing out the undefined
instruction itself.
Test Plan: * compiled/booted on an IPQ4019 SoC AP

This is for the Qualcomm Atheros quad-core ARMv7 SoC with built-in
2x2 2GHz and 5GHz ath10k devices.
It's enough (with an upcoming set of config files) to netboot
on an ASUS router I have here and get to a single core mountroot
prompt.
The upcoming QCA ipq401x support detects the CP14 debug features,
but any attempt to use it causes an undefined instruction error.
It apparently needs a specific TZ image loaded by the early bootloader
(SBL) in order to enable these kinds of features.
So add a new kernel option that explicitly disables this in the
arm code - the debugger works fine without it.
These are hardware configuration options which are required in
the linux/openwrt device trees for the IPQ4018/IPQ4019 devices.
Since this isn't obtained from linux upstream but instead from
openwrt, this can't go in contrib; instead it is going in
sys/dts/include/ .

This function was originally carved out of in6_pcbbind(), which
is in in6_pcb.c. This function also uses KPI private to the PCB
database - in_pcb_lport().
Add necessary bits to detect ELF format on Linux/aarch64; note that
Linux calls it aarch64 where we would typically call it arm64 (uname -m)

Timecounter registration is dynamic, i.e., there is no requirement that
timecounters must be registered during single-threaded boot. Loadable
drivers may in principle register timecounters (which can be switched to
automatically). Timecounters cannot be unregistered, though this could
be implemented.
Registered timecounters belong to a global linked list. Add a mutex to
synchronize insertions and the traversals done by (mpsafe) sysctl
handlers. No functional change intended.

Add a SIG_FOREACH macro that can be used to iterate over a signal set.
This is a bit cleaner and more efficient than calling sig_ffs() in a
loop. The implementation is based on BIT_FOREACH_ISSET(), except
that the bitset limbs are always 32 bits wide, and signal sets are
1-indexed rather than 0-indexed like bitset(9) sets.
issignal() cannot really be modified to use SIG_FOREACH() directly.
Take this opportunity to split the function into two explicit loops.
I've always found this function hard to read and think that this change
is an improvement.
Remove sig_ffs(), nothing uses it now.

This patch modifies the function that does the Close RPC (nfsrpc_closerpc)
so that it does not use the open_owner (nfso_own) for NFSv4.1/4.2.
Use of the seqid in the open_owner structure is only needed for NFSv4.0.
Same applies to a NFSERR_STALESTATEID reply, which should only happen
for NFSv4.0. This allows nfsrpc_closerpc() to be called when nfso_own
is no longer valid. This, in turn, allows nfsrpc_closerpc() to be called
after the shared lock on the clientID is released, for NFSv4.1/4.2.
This is being done to prepare the code for a future patch that fixes
the case where an NFSv4.1/4.2 server replies NFSERR_DELAY to a Close
operation.

Linux KPIs like pci_resource_start/len assume that BARs have been
allocated, but FreeBSD lazily allocates BARs if it cannot allocate the
firmware-allocated BARs. Thus using the Linux KPIs must force allocation
of the BARs rather than returning 0 for the start and length, which can
crash drm-kmod drivers that assume the BARs are valid. This is needed
for the AMDGPU driver to be able to attach on SiFive's HiFive Unmatched.

PIE and shared objects usually have many relative relocations. In
2017/2018, a compact relative relocation format RELR was proposed on
https://groups.google.com/g/generic-abi/c/bX460iggiKg/m/GxjM0L-PBAAJ
("Proposal for a new section type SHT_RELR") and is a pre-standard.
RELR usually takes 3% or smaller space than R_*_RELATIVE relocations.
The virtual memory size of a mostly statically linked PIE is typically
5~10% smaller.
ld.lld --pack-dyn-relocs=relr emits RELR relocations. DT_RELR has been
adopted by Android bionic, Linux kernel's arm64 port, Chrome OS (patched
glibc).
This patch adds DT_RELR support to FreeBSD rtld-elf.

This patch moves release of the shared clientID lock from nfsrpc_close()
just after the nfscl_doclose() call to the end of nfscl_doclose() call.
This does make the code cleaner, since the shared lock is acquired at
the beginning of nfscl_doclose(). The only semantics change is that
the code no longer drops and reaquires the NFSCLSTATELOCK() mutex,
which I do not believe will have a negative effect on the NFSv4 client.
This is being done to prepare the code for a future patch that fixes
the case where an NFSv4.1/4.2 server replies NFSERR_DELAY to a Close

This avoids spurious drop offs as EMPTY is passed regardless of the
actual path name.
Pushign the work inside the lookup instead of just ignorign the flag
allows avoid checking for empty pathname for all other lookups.
On kernels compiled with 'options TSLOG', record for each process ID:
* The timestamp of the fork() which creates it and the parent
process ID,
* The first path passed to execve(), if any,
* The first path resolved by namei, if any, and
* The timestamp of the exit() which terminates the process.
Expose this information via a new sysctl, debug.tslog_user.
On kernels lacking 'options TSLOG' (the default), no information is
recorded and the sysctl does not exist.
Note that recording namei is needed in order to obtain the names of
rc.d scripts being launched, as the rc system sources them in a
subshell rather than execing the scripts.
With this commit it is now possible to generate flamecharts of the
entire boot process from the start of the loader to the end of
