When we destroy an interface while the jail containing it is being
destroyed we risk seeing a race between if_vmove() and the destruction
code, which results in us trying to move a destroyed interface.
Protect against this by using the ifnet_detach_sxlock to also covert
if_vmove() (and not just detach).

Prior to fuse protocol version 7.9, the fuse_entry_out structure had a
smaller size. But fuse_vnop_create did not take that into account when
working with servers that use older protocols. The bug does not matter
for servers which don't use file handles or open flags (the only fields
affected).

During a FUSE_WRITE, the kernel requests the server to write a certain
amount of data, and the server responds with the amount that it actually
did write. It is obviously an error for the server to write more than
it was provided, and we always treated it as such, but there were two
problems:
* If the server responded with a huge amount, greater than INT_MAX, it
would trigger an integer overflow which would cause a panic.
* When extending the file, we wrongly set the file's size before
validing the amount written.

Perhaps surprisingly, and contrary to the expectations of
path_test:path_event, NOTE_LINK events are not raised when a file is
unlinked. Prior to commit bf13db086b, the test happened to work
because unlinking the file would cause the vnode to be recycled, and
EVFILT_VNODE knotes deliver an event with EV_EOF set when the vnode is
doomed. Since the test did not verify the note type, the test
succeeded. After commit bf13db086b, the vnode is not recycled after
being unlinked and so the test hangs.
Fix the test by waiting for NOTE_DELETE instead, and check that we got
the note that we expected.

Formerly fusefs would pass up the stack any error value returned by the
fuse server. However, some values aren't valid for userland, but have
special meanings within the kernel. One of these, EJUSTRETURN, could
cause a kernel page fault if the server returned it in response to
FUSE_LOOKUP. Fix by validating all errors returned by the server.
Also, fix a data lifetime bug in the FUSE_DESTROY test.

* We never send FUSE_LOOKUP for the root inode, since its inode number
is hard-coded to 1. Therefore, we should not send FUSE_FORGET for it,
lest the server see its lookup count fall below 0.
* During VOP_RECLAIM, if we are reclaiming the root inode, we must clear
the file system's vroot pointer. Otherwise it will be left pointing
at a reclaimed vnode, which will cause future VOP_LOOKUP operations to
fail. Previously we only cleared that pointer during VFS_UMOUNT. I
don't know of any real-world way to trigger this bug.

In some configurations the firmware may pass memory regions that are
not page sized or aligned, e.g. when using 16k pages on arm64. If this
is the case we will calculate many small regions because the alignment
is applied before being inserted. As we round the start up and end down
this will leave a 1 page hole between what should have been a single
region.
Fix by keeping the original alignment until we are just about to insert
the region into the avail array.
