When typing command "btrfs send --help" or "btrfs receive --help",
the help information of the commands is incomplete, which only
shows a short usage.
This patch helps to display the complete infomation of the commands.

The definition of the function open_file_or_dir() is moved from common.c
to utils.c in order to be able to share some common code between scrub
and the device stats in the following step. That common code uses
open_file_or_dir(). Since open_file_or_dir() makes use of the function
dirfd(3), the required XOPEN version was raised from 6 to 7.

The new infrastructure offloads checking number of arguments passed to a
command to individual command handlers. Fix them up accordingly.

This completely replaces the existing subcommand infrastructure, which
is not flexible enough to accomodate our needs. Instead of a global
command table we now have per-level tables and command group handlers,
which allows command-group-specific handling of options and subcommands.
The new parser exports a clear interface and gets out of the way - all
control over how matching is done is passed to commands and command
group handlers.
One side effect of this is that command implementors have to check the
number of arguments themselves - patch to fix up all existing commands
follows.
