This patch updates help/document of "btrfs device remove" in two points:
1. Add explanation of 'missing' for 'device remove'. This is only
written in wikipage currently.
(https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices)
2. Add example of device removal in the man document. This is because
that explanation of "remove" says "See the example section below", but
there is no example of removal currently.

User Kasijjuf points out the VFS initialism is not explained anywhere.
While this could be fixed, the whole note about inability to delete the
device by which the filesystem has been mounted, is wrong.

Currently, `btrfs device stats` returns non-zero only when there was an
error getting the counter values. This is fine for when it gets run by a
user directly, but is a serious pain when trying to use it in a script or
for monitoring since you need to parse the (not at all machine friendly)
output to check the counter values.
This patch adds an option ('-s') which causes `btrfs device stats`
to set bit 6 in the return code if any of the counters are non-zero.
This greatly simplifies checking from a script or monitoring software if
any errors have been recorded. In the event that this switch is passed
and an error occurs reading the stats, the return code will have bit
0 set (so if there are errors reading counters, and the counters which
were read were non-zero, the return value will be 65).

This patch introduces new option <devid> for the command
btrfs device delete <device_path|devid>[..] <mnt>
In a user reported issue on a 3-disk-RAID1, one disk failed with its
SB unreadable. Now with this patch user will have a choice to delete
the device using devid.
The other method we could do, is to match the input device_path
to the available device_paths with in the kernel. But that won't
work in all the cases, like what if user provided mapper path
when the path within the kernel is a non-mapper path.
This patch depends on the below kernel patch for the new feature to work,
however it will fail-back to the old interface for the kernel without the
patch

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

A few minor benefits:
* editors set highliting according to the extensions
* web access to the git repository (github) renders the .asciidoc
files:
* we can link to them from the wiki
* the files are editable via browser and such editations can be
submitted for merge easily
