net_open() does replace f_devdata with pointer to netdev_sock,
this will cause memory leak when device is closed, but also does
alter the devopen() logic.
We should store &netdev_sock to dev->d_opendata instead, this
would preserve and follow the devopen() logic.

Without this patch, if a NFSv4.1/4.2 server replies NFSERR_DELAY to
a Close operation, the client loops retrying the Close while holding
a shared lock on the clientID. This shared lock blocks returns of
delegations, even though the server has issued a CB_RECALL to request
the delegation return.
This patch delays doing a retry of a Close that received a reply of
NFSERR_DELAY until after the shared lock on the clientID is released,
for NFSv4.1/4.2. To fix this for NFSv4.0 would be very difficult and
since the only known NFSv4 server to reply NFSERR_DELAY to Close only
does NFSv4.1/4.2, this fix is hoped to be sufficient.
This problem was detected during a recent IETF working group NFSv4
testing event.

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.

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/ .

Tested:
* IPQ4019 ASUS RT-AC58U AP, initial bootstrapping
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().

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.
