btrfs-progs: bump to version 3.16, fix static linking

The original aim of this patch was to fix static linking of
btrfs-progs. In order to implement this in the form of patches that
can potentially be upstreamed, this patch first bumps the btrfs-progs
package to the latest upstream stable version. It then:

 - Reworks the existing documentation disabling patch in a form that
   can potentially be upstreamed.

 - Adds a patch to support static building of the btrfs-progs
   binaries.

Both patches have been submitted upstream, see
http://article.gmane.org/gmane.comp.file-systems.btrfs/38145.

Fixes:

+Subject: [PATCH 1/2] Add support for DISABLE_DOCUMENTATION
+
+This commit adds the support for a make variable named
+"DISABLE_DOCUMENTATION", which allows to disable the build of the
+documentation. This is useful in contexts where the tools needed to
+build the documentation are not necessarily available.
