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 updates btrfs-completion:
- add "filesystem du" and "rescure zero-log"
- restrict _btrfs_mnts to show btrfs type only
- add more completion in last case statements
(This file contains both spaces/tabs and may need cleanup.)

The function uses the reverse CRC32C table to quickly calculate a
4-byte suffix, that when added to the original data will make it
match desired checksum.

Function find_collision sometimes generated file names with non-printable

First patch causes test-convert fails. This is because
generate_dataset() creates a name containing trailing spaces for
"slow_symlink" type, and cause getfacl error in convert_test_perm().
(This is not noticed since original run_check_stdout() throws away the
error.)
Fix this by use space for delimiter for cut.

run_check_stdout() uses "... | tee ... || _fail". However, since tee
won't fail, _fail() is not called even if first command fails.
Fix this by checking PIPESTATUS in the end.

[Bug]
If using mkfs.btrfs with "-r" parameter and specified directory has
fifo/socket/char/block special file, then created filesystem can't pass
fsck:
------
checking fs roots
unresolved ref dir 241158 index 3 namelen 9 name S.dirmngr filetype 0 errors 80, filetype mismatch
ERROR: errors found in fs roots
------
[Reason]
Btrfs dir items/indexes records inode type, while "-r" only handles
directories, regular files and symlink, it makes such special files type
to be regular file and caused the problem.
[Fix]
Add missing types for add_directory_items(), so that result of
"mkfs.btrfs -r" can pass mkfs.

Some of the tree roots are now created in a loop, where the code is just
copypasted. We now make use of the reference_root_table to translate

Since cmd_inspect_rootid() calls btrfs_open_dir(), it rejects a file to
be specified. But as the document says, a file should be supported.
This patch introduces btrfs_open_file_or_dir(), which is a counterpart
of btrfs_open_dir(), to safely check and open btrfs file or directory.
The original btrfs_open_dir() content is moved to btrfs_open() and shared
by both function.

Sometimes it's needed to do a check on a mounted filesystem. This should
work fine on a quiescent filesystem or a read-only mount. Changes on the
block device done by kernel might confuse the userspace checker and it
might crash when it reads some stale data.
Repair without mount checks is not supported right now.
