sys/vfs/fuse: Add initial FUSE support
The basic code design comes from FreeBSD, but the code is written
from scratch. It was just easier to write from scratch than trying to
port sys/fs/fuse/* in FreeBSD for various reasons. Note that this is
to implement FUSE API/ABI, but not to be compatible with FreeBSD
implementation which contains FreeBSD specific sysctls, etc.
The initial version doesn't support FUSE_WRITE by disabling
VOP_WRITE() by returning EOPNOTSUPP. It currently works with simple
write(2) calls like dd(1) via direct I/O, but not when syncer thread
or mmap(2) gets involved under non trivial conditions. It looks to
be doable with custom VOP_GETPAGES() and VOP_PUTPAGES(), but if not
then it requires some changes to sys/kern/* and sys/vm/* to properly
support writes.
Besides above, this initial version supports basic FUSE operations
invoked from file related system calls via FUSE VOP's, but not things
like FUSE_IOCTL, FUSE_POLL, FUSE_FALLOCATE, etc. Although dmesg says
FUSE 7.28, don't expect it to support everything 7.28 (or anywhere
close to 7.28) says it has.
FUSE will be dropped from DragonFly releases until it gets stabilized
to certain extent including above, at least for write support.

sys/kern: Add struct file* arg to VOP_{GETATTR,SETATTR,READ,WRITE,FSYNC,READDIR}
This commit changes VOP interface to support FUSE API/ABI.
It just adds an additional struct file* argument to VOP's, so that
FUSE VOP's can access *fp pointer (currently accessible only from
caller of VOP's if any, with exception of VOP_OPEN(), VOP_CLOSE(),
etc) and make use of its ->private_data pointer.
FUSE API/ABI requires FUSE to maintain a per file (usually per file
descriptor) data called fh. The fh is an opaque data whose purpose
may differ among userspace filesystems, but typically used to store
file descriptor value or arbitrary userspace address used by the
userspace filesystem process.
Below diagram illustrates typical flow of maintaining fh. The
userspace filesystem uses fd obtained from opening backing store
(e.g fd for regular file, socket, etc) for fh, as a consequence of
end user's open(2) syscall, and expects FUSE to maintain that value
for future use as an identifier for userspace.
* Notes on Linux VFS I/F vs BSD VFS I/F:
In Linux, supporting the concept of fh is quite straight forward since
Linux kernel has functions vector built around (opened)file including
things like mmap(2) handler, in addition to a vector built around
inode.
But since DragonFly doesn't have a vector built around file (other
than a simple struct fileops, which doesn't meet requirements of fh),
this change was needed for selected VOP's as minimum requirements
for initial FUSE API/ABI support.
