0dc332bff2 Add fspacectl(2), vn_deallocate(9) and VOP_DEALLOCATE(9).
fspacectl(2) is a system call to provide space management support to
userspace applications. VOP_DEALLOCATE(9) is a VOP call to perform the
deallocation. vn_deallocate(9) is a public KPI for kmods' use.

The purpose of proposing a new system call, a KPI and a VOP call is to
allow bhyve or other hypervisor monitors to emulate the behavior of SCSI
UNMAP/NVMe DEALLOCATE on a plain file.

fspacectl(2) comprises of cmd and flags parameters to specify the
space management operation to be performed. Currently cmd has to be
SPACECTL_DEALLOC, and flags has to be 0.

fo_fspacectl is added to fileops.
VOP_DEALLOCATE(9) is added as a new VOP call. A trivial implementation
of VOP_DEALLOCATE(9) is provided.

4e860bd5da pf tests: make killstate:match more robust
Only lists the states relevant to the connection we're killing.
Sometimes there are IPv6 related states (due to the usual IPv6
background traffic of router solicitations, DAD, ...) that causes us to
think we failed to kill the state, which in turn caused the test to fail
intermittently.

18b19f8c6e fusefs: correctly set lock owner during FUSE_SETLK
During FUSE_SETLK, the owner field should uniquely identify the calling
process.  The fusefs module now sets it to the process's pid.
Previously, it expected the calling process to set it directly, which
was wrong.

libfuse also apparently expects the owner field to be set during
FUSE_GETLK, though I'm not sure why.

5403f2c163 fusefs: ensure that FUSE ops' headers' unique values are actually unique
Every FUSE operation has a unique value in its header.  As the name
implies, these values are supposed to be unique among all outstanding
operations.  And since FUSE_INTERRUPT is asynchronous and racy, it is
desirable that the unique values be unique among all operations that are
"close in time".

Ensure that they are actually unique by incrementing them whenever we
reuse a fuse_dispatcher object, for example during fsync, write, and
listextattr.
