Scrub can be invoked to scrub only a single device of a (mounted) filesystem.
The code determines whether the given path is a mountpoint of a filesystem
by issueing a btrfs-specific ioctl to it. Only in case of EINVAL it assumed
it may be a device, all other errnos just caused it fail, but some devices
(correctly) return ENOTTY. This patch adds this to the error check.

There, 'char' is unsigned, so once assigned '-1' from getopt, it gets
the value 255. Then, it compared to '-1' gives false.

The kernel uses unsigned long long for u64, but PPC64 uses unsigned
long by default. This results in compilation warnings such as:
print-tree.c:333: warning: format '%llu' expects type 'long long
unsigned int', but argument 4 has type 'u64'
To fix this, the macro __KERNEL__ needs to be defined before including
the file <asm/types.h>. This can be done by defining the macro in
"kerncompat.h" and making it the first included file in the relevant
header files; this fixes the compiler warnings on PPC64.

The function scrub_fs_info( ) closes and reopen a file handle
passed as argument, when a caller uses the file handle even after the
call.
The function scrub_fs_info( ) is updated to remove the file handle
argument, and instead uses a private own file handle.
The callers are updated to not pass the argument.
The new infrastructure offloads checking number of arguments passed to a
command to individual command handlers. Fix them up accordingly.

Separate every command group into its own file (cmds_<group>.c) and
rearrange includes. Remove btrfs_cmds.c.
