We've been using asciidoc that's written in python2, which is going to
be phased out and deprecated next year. There's a replacement,
asciidoctor. Add a configure-time detection which tool is available,
update Documentation/Makefile.in.
The original asciidoc tool is still preferred as it produces slightly
better output. The file asciidoc.conf does not have a direct equivalten
in asciidoct and would need to be replaced by extension written in ruby.
The differences:
- the <literal> are not automatically underlined and are less visible in
the generated manual page, but it's still acceptable
- the inline CSS for the html output looks subjectively worse, is less
compact and colourful

There will be a plain file tracking the last released version.
The rest will be simplified to print it where needed. The version
augmented by the current git status was not working anyway since we've
switched to autoconf. The result of version.h with the potential git
status was generated at configure time, which does not mean it's
accurate regarding the git status.

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.

Before the change configure refused to accept it's defaults explicitly:
$ ./configure --enable-convert --with-convert=ext2,reiserfs
...
configure: error: unknown tokens for --with-convert: ,
After the change both converters are enabled:
$ ./configure --enable-convert --with-convert=ext2,reiserfs
...
btrfs-convert: yes (ext2,reiserfs)

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.

This patch adds support to convert reiserfs file systems in-place to btrfs.
It will convert extended attribute files to btrfs extended attributes,
translate ACLs, coalesce tails that consist of multiple items into one item,
and convert tails that are too big into indirect files.
This requires that libreiserfscore 3.6.27 be available.

It's not really necessary to configure and regenerate Makefiles in cases
like adding a new source file. The build environment and optional
features are not affected by that.

The FIEMAP_EXTENT_SHARED fiemap flag was introduced in 2.6.33. If the
headers do not provide the definition, the build will fail. The support
of the fiemap sharing depends on the running kernel. There are still
systems with 2.6.32 kernel headers but running newer versions.
To support such environment, don't fail build, provide own defintion of
the structure and detect if there's an old kernel in use in the relevant
command (btrfs fi du).

The new convert framework copies code from current dumpe2fs, which uses
BIGALLOC feature introduced in e2fsprogs v1.42.
While there are a lot of enterprise distributions which are still using
v1.41 e2fsprogs, this will cause compile error for them.
This patch introduces backward compatibility for new convert framework,
by manually introduce macros for ext2 BIGALLOC feature.

Systemd's btrfs rule runs btrfs dev ready on each device
as it's discovered. The btrfs command is executed as a builtin
command via an IMPORT{builtin} rule, which means it gets
executed at rule evaluation time, not rule execution time. That
means that the device mapper links haven't been setup yet and the only
nodes that can be depended upon are /dev/dm-#. That we see
/dev/mapper/name names in /proc/mounts is only because we replace the
device name we have cached with the one passed in via mount. If
we have a multi-device file system and the primary device is removed,
the remaining devices will show /dev/dm-#. In addition, if the
udev rule is executed again by someone generating a change event (e.g.
partprobe), the names are also replaced by the /dev/dm-# names.
This patch adds a new rule that adds a run rule that calls btrfs dev
ready again using the device mapper links once they're created.

The conversion to autotools changed the default prefix to /usr. There's
no reason to diverge. Distributions builds set prefix the /usr path and
local builds are supposed to go to /usr/local .

- define basic default CFLAGS in configure.ac, because:
* autoconf default is -g -O2, but btrfs uses -g -O1
* it's better to follow autoconf; standard way to modify
CFLAGS is to call: CFLAGS="foo bar" ./configure
- move all flags to one place in Makefile.in
- don't use AM_CFLAGS, the CFLAGS and STATIC_CFLAGS are enough
- don't mix objects and flags in $LIBS, it's more readable to
add $(libs) to make rules
