For environments that require certified implementations of cryptographic
primitives allow to select a library providing them. The requirements
are SHA256 and BLAKE2 (with the 2b variant and 256 bit digest).
For now there are two: libgrcrypt and libsodium (openssl does not
provide the BLAKE2b-256). Accellerated versions are typically provided
and automatically selected.

The C libbtrfsutil library isn't very useful for scripting, so we also
want bindings for Python. Writing unit tests in Python is also much
easier than doing so in C. Only Python 3 is supported; if someone really
wants Python 2 support, they can write their own bindings. This commit
is just the scaffolding.

The kernel 4.14 supports zstd, for version parity the btrfs-progs now
require libzstd by default. This can still be disabled by
./configure --disable-zstd.

Adds zstd support to the btrfs program. An optional dependency on libzstd
>= 1.0.0 is added. Autoconf accepts `--enable-zstd' or `--disable-zstd' and
defaults to detecting if libzstd is present using `pkg-config'.
The patch is also available in my fork of btrfs-progs [1], which passes
Travis-CI with the new tests. The prebuilt binary is available there.
I haven't updated Android.mk.

The file sys/acl.h is part of libacl and if the development package is
not installed, build of btrfs-convert fails.
We do not link against libacl nor use the functions provided by libacl. The
ACL_* values are directly read from the extN data, so it's more part of the
on-disk format rather than an interface to libacl.
The dependency on libacl is completely dropped.

With the commit 002d021c (committed October 2011)
btrfsctl, btrfs-vol, btrfs-show were declared deprecated.
The last patches related to these commands are dated December 2010.
These tools are replaced by the "btrfs" tool in all the
functionality.
This commit removes all the related code.

Subject: [PATCH] btrfs-progs-unstable: replace debug-tree to btrfs-debug-tree in INSTALL
debug-tree doesn't exist after btrfs-progs installed.
Use btrfs-debug-tree to print FS metadata in text form,
not debug-tree.

Hi all,
enclose you can find a patch which improves the help of the btrfs commands,
updates the INSTALL file and the btrfs (command) man page.
Regarding the help of the btrfs command:
- moved the "subvolume set-default" command in the "subvolume" commands group
- removed a wrong new line
- small tweak on the basis of Andreas suggestion
Regarding the btrfs command man page:
- renaming the command "device balance" in "filesystem balance" (thanks to
Andreas Phillipp to highlight that)
- adding the entry "subvolume find-new"
- document the switches of the command "filesystem defrag"
- document the <devid> facility of the command "filesystem resize"
- small tweak on the basis of Andreas suggestion
Regarding the INSTALL file, which was very old, I removed the reference of the
old btrfsctl utility and changed the examples using the btrfs command.
I removed the old (and now wrong) statement about the inability to delete a
subvolume/snapshot
Chris, you can pull the patch from the branch "help_cleanup" of the following
repository.
http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git
(or you can browse the changes at
http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git/?p=btrfs-
progs-unstable-all.git;a=summary)
The patch is very simple: only updates the man page, the INSTALL file and
moves/updates some lines in the help of btrfs command. Comments are welcome.
Regards
G.Baroncelli
