We are going to unify enabling filesystem features via option -O.
For now, use btrfstune to enable the features.

This fixes up the progs to properly deal with skinny metadata. This adds the -x
option to mkfs and btrfstune for enabling the skinny metadata option. This also
makes changes to fsck so it can properly deal with the skinny metadata entries.

In "[ \fB\-f\fP\fI ]", the "\fI" will result in the front half "["of
"[ -f ]" doesn't the back half "]"; When you issue the command
"man mkfs.btrfs", you will see the difference.

I missed updating the mkfs.btrfs usage() when I added the
option to force fs overwrite.
Update that, and while we're at it add a long option, since
all other commands have long counterparts.

The core of this is shamelessly stolen from xfsprogs.
Use blkid to detect an existing filesystem or partition
table on any of the target devices. If something is found,
require the '-f' option to overwrite it, hopefully avoiding
disaster due to mistyped devicenames, etc.
# mkfs.btrfs /dev/sda1
WARNING! - Btrfs v0.20-rc1-59-gd00279c-dirty IS EXPERIMENTAL
WARNING! - see http://btrfs.wiki.kernel.org before using
/dev/sda1 appears to contain an existing filesystem (xfs).
Use the -f option to force overwrite.

This does introduce a requirement on libblkid.

Patch rebased because of changes in mkfs.c but otherwise the same
as created by Josef Bacik
SSD's do not gain anything by having metadata DUP turned on. The underlying
file system that is a part of all SSD's could easily map duplicate metadat
blocks into the same erase block which effectively eliminates the benefit of
duplicating the metadata on disk. So detect if we are formatting a single
SSD drive and if we are do not use DUP. Thanks,

Kept the name with the name in, so that further processing such as
BUILD_DATE BUILD_VERSION etc. could be included later.
All man pages included in the man directory to avoid file cluttering.
