Thomas Petazzoni a2d7725e4d 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 2/2] Improve static building and installation
This commit improves the static-only building of btrfs-progs, and adds
support for installing the static only tools:
- It now ensures that all programs are built statically, not only a
small subset of them, by defining 'progs_static' from the existing
'progs' variable.
- It changes the order of libraries in the btrfs-%.static rule so
that -lpthread (part of STATIC_LIBS) appears *after* the '$($(subst
-,_,$(subst .static,,$@)-libs))' logic, which brings in
-lcom_err. This is needed because libcom_err.a uses the semaphore
functions, which are available in the pthread library.
- Adds the necessary rules to generate the btrfsck.static link and
btrfstune.static binary.
- Adds an 'install-static' target to install the static
binaries. Note that they are renamed to not carry a '.static'
suffix.
