There's an awkward asymmetry between btrfs device add and btrfs device
delete. Resolve this by aliasing delete to remove.

We're also going to want to support aliases, so rather than adding
another member, replace "hidden" with a "flags" member.

Running 'btrfs' without arguments will print complete help that spans
a lot of lines and is really helpful. Print only subcommand group
names with short descriptions, similar to what 'git' does.

The variable argv0_buf was duplicated and the changes done in utils.c
were not propagated to help.c. So if an unknown commandline token was
found, the error message did not contain the known part:
$ btrfs scrub test
: unknown token 'test'
instead of
$ btrfs scrub test
btrfs scrub: uknown token 'test'

This fixes various compilation errors where PATH_MAX and XATTR_SIZE_MAX
were missing. To my knowledge, this should have no bad side effects.

To let the independent tools(e.g. btrfs-image, btrfs-convert, etc.)
share the convenience of check_argc_* functions, just move it into
utils.c.
Also add a new function "set_argv0" to set the correct tool name:
*btrfs-image*: too few arguments
The original btrfs* tools work as before.

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.
