Move the timerfd impelemntation from linux compat code to sys/kern. Use
it to implement the new system calls for timerfd. Add a hook to kern_tc
to allow timerfd to know when the system time has stepped. Add kqueue

If a socket is marked as cannot read anymore, drop chunks which
should be added to a control element in the receive queue.
This is consistent with dropping control elements instead of
adding them in the same situation.

pf_route() sends traffic to a specified next hop over a specific
interface. The next hop is obtained in pf_map_addr() but the interface
is obtained directly via r->rpool.cur->kif` outside of the lock held in
pf_map_addr() in multiple places around pf. The chosen interface is not
stored in source node.
Move the interface selection into pf_map_addr(), have the function
return it together with the chosen IP address and ensure its stored
in struct pf_ksrc_node, store it in the source node and use the stored
value when needed.

In commit c7cffd65c5 the function ether_8021q_frame() was slightly
refactored to use pointer of struct ether_8021q_tag as parameter qtag to
include the new option proto.
It is wrong to write to qtag->pcp as it will effectively change the memory
that qtag points to. Unfortunately the transmit routine of if_vlan parses
pointer of the member ifv_qtag of its softc which stores vlan interface's
PCP internally, when transmitting mbufs that contains PCP the vlan
interface's PCP will get overwritten.
Fix by operating on a local copy of qtag->pcp. Also mark 'struct ether_8021q_tag'
as const so that compilers can pick up such kind of bug.

For amd64, i386, arm, and riscv, i.e. all architectures except arm64,
the custom implementation is provided since we maintain the bitmask of

Arm64 uses somewhat naive iteration over CPUs and match current vmspace'
pmap with the argument. It is not guaranteed that vmspace->pmap is the
same as the active pmap, but the inaccuracy should be toleratable.

We can end up with a domain having no CPUs capable of receiving I/O
interrupts. This can occur, for example, when all APIC IDs in a given
domain are 256 or greater, and we have no IOMMU.
In this case disable per-domain interrupt support, effectively reverting
to the behaviour before commit a48de40bcc ("Only use CPUs in the
domain the device is attached to for default"). This has a performance
impact but at least allows the system to be functional. It is a stop-
gap until we can rely on the presence of an IOMMU on all x86 platforms.
Thanks to AMD for providing the high-thread-count machine I used for
testing this change, and to cperciva for testing on other hardware.

Restructure parts of pctrie code to make it more compatible with the
needs of vm_radix code.
1. End passing function pointers for memory management.
By breaking insertion into two functions, the call for allocating
memory can happen at the top level and be inlined, rather than
happening via an function pointer to a memory allocator.
By changing the remove function slightly, freeing of memory, when
necessary, can happen at the top level and be inlined.
By turning the reclamation code into two functions, one for starting
iteration over to-be-freed nodes and the other continuing it, all the
freeing can happen at the top level and be inlined.
2. Offer a version of remove that does not panic and returns the freed
value (or NULL).
3. Offer a 'replace' operation, to replace one leaf with another that
has the same key.
These are three of the roadblocks that prevent code sharing between
pctrie and vm_radix code.
