fuse_main(3): Support general fuse options via fuse_parse_cmdline(3)

* Prototypes for fuse_new(3), fuse_mount(3), and fuse_unmount(3) now
  matches to the original fuse interface.

* Add fuse_daemonize(3): needs to have a different prototype,
  otherwise we can't use puffs_daemon(3).

* Remove fuse_setup(3) and fuse_teardown(3). These obsolete functions
  has already been removed from the original interface.

* fuse_main(3) now supports the following command-line options
  compatible with the original fuse:

  -h, --help      print help message
  -V, --version   print library version (currently does nothing)
  -d, -o debug    enable debug output (PUFFS_FLAG_OPDUMP), implies -f
  -f              foreground mode
  -s              single threaded mode (always enabled for now)
  -o fsname=NAME  explicitly set the name of the file system

* fuse_main(3) now daemonizes the process by default. This is for the
  compatibility with the original fuse.

.Sh DESCRIPTION
.Nm
is a reimplementation of the file system in user space subsystem.
Operations are transported from the kernel virtual file system layer
to the concrete implementation behind
.Nm ,
where they are processed and results are sent back to the kernel.
.Pp
It uses the framework provided by the
.Xr puffs 3
subsystem, and, through that, the kernel interface provided by
.Xr puffs 4 .
