Add support for HV_PARTITION_CREATION_FLAG_SMT_ENABLED_GUEST
to allow userspace VMMs to enable SMT for guest partitions.

Expose this via new MSHV_PT_BIT_SMT_ENABLED_GUEST flag in the UAPI.

Without this flag, the hypervisor schedules guest VPs incorrectly,
causing SMT unusable.

   - Fix an issue with SOCKET_URING_OP_SETSOCKOPT for netlink sockets,

   - Remove a redundant SQPOLL check in ring creation

   - Kill dead accounting for zero-copy send, which doesn't use ->buf

     for. Still within the allowed limits.

   - Fix for IORING_OP_PIPE's handling of direct descriptors

   - Tweak to the API for the newly added BPF filters, making them
     more future proof in terms of how applications deal with them

   - A few fixes for zcrx, fixing a few error handling conditions

Musl defines its own struct ethhdr and thus defines __UAPI_DEF_ETHHDR to
zero. To avoid struct redefinition errors, user space is therefore
supposed to include netinet/if_ether.h before (or instead of)
linux/if_ether.h. To relieve them from this burden, include the libc
header here if not building for kernel space.

It's quite possible that opcodes that have payloads attached to them,
like IORING_OP_OPENAT/OPENAT2 or IORING_OP_SOCKET, that these paylods
can change over time. For example, on the openat/openat2 side, the
struct open_how argument is extensible, and could be extended in the
future to allow further arguments to be passed in.

Allow registration of a cBPF filter to give the size of the filter as
seen by userspace. If that filter is for an opcode that takes extra
payload data, allow it if the application payload expectation is the
same size than the kernels. If that is the case, the kernel supports
filtering on the payload that the application expects. If the size
differs, the behavior depends on the IO_URING_BPF_FILTER_SZ_STRICT flag:

1) If IO_URING_BPF_FILTER_SZ_STRICT is set and the size expectation
   differs, fail the attempt to load the filter.

2) If IO_URING_BPF_FILTER_SZ_STRICT isn't set, allow the filter if
   the userspace pdu size is smaller than what the kernel offers.

3) Regardless if IO_URING_BPF_FILTER_SZ_STRICT, fail loading the filter
   if the userspace pdu size is bigger than what the kernel supports.

An attempt to load a filter due to sizing will error with -EMSGSIZE.
For that error, the registration struct will have filter->pdu_size
populated with the pdu size that the kernel uses.
