Personally I avoid using non-ASCII letters in commit author information
and most source files, thus you can often see my name with L instead of
L with stroke. The usual exceptions are AUTHORS and .mailmap file, so I
can remain using ASCIIfied version, yet `git shortlog` shows my name
properly.

It was accidentally changed when I was amending Dan's patch, which
ended in the repo as commit:
b6f60de Add support for deleting directories with -a -E.

metastore depends now on libbsd, because of strmode() function.
This commit fixes issue #28.

During implementation and tests of new dump action, I've noticed that
while non-textual values in extended attributes were properly stored in
.metadata file, retrieving them from it was simply broken, i.e.
anything beyond first null byte was zeroed.
Small quantum of solace is the fact that apparently metastore users
rarely use extended attributes or at least rarely with non-textual
values, because otherwise they would surely report such crucial bug.
Let's perform simple test to show the problem:
$ mkdir -p ~/testxattr/ && cd ~/testxattr/ && touch test
$ setfattr -n user.txt -v "tekst" test
$ setfattr -n user.bin -v 0x020100ff00 test
$ getfattr -d -e hex test
# file: test
user.bin=0x020100ff00
user.txt=0x74656b7374
$ metastore -s test
$ OFFSET=$(($(grep -abo user.bin .metadata | sed 's/:.*//')+8+1+4))
$ xxd -p -l5 -s $OFFSET .metadata
020100ff00
So far everything seems fine, i.e. user.bin xattr is properly stored.
$ metastore -c test
./test: xattr
Apparently on-disk test xattrs differ from those in metadata file,
even though they should not!
Let's apply those from metadata file and show how they look on-disk.
$ metastore -a test
./test: changing metadata
./test: removing xattr user.bin
./test: adding xattr user.bin
$ getfattr -d -e hex test
# file: test
user.bin=0x0201000000
user.txt=0x74656b7374
Oh no! Extended attribute with non-textual data has been corrupted now.
But no more, because this commit fixes it!
As long as you haven't stored corrupted xattrs in metadata file, you can
still recover on-disk ones by applying them from metadata file using
fixed version of metastore.

Turn

Wording has been changed only in Makefile, where:

canonicalize_file_name() is not portable, but it can be easily replaced.
Now we're a bit friendlier to non-GNU libcs, like musl.

This is analagous script to the pre-commit one, but it applies metadata
automatically after a git checkout.

Store extradirs list ordered by pathlen descendingly, so one traversal
should be enough to remove empty dirs.

Update extradirs list after successful rmdir(), so already removed
directory won't be provided to rmdir() again.

This is analagous to the -e option to create empty directories.
It simply removes them when they are not present in the metadata.

xattr.h from libattr is not necessary, because glibc ships its own
xattr.h for many years already (since v2.3, so it's like 13 years).
libattr's header included errno.h, thus now it needs to be included
explicitly.

I think that adding this directory 3 years ago to the repository was
a mistake. If there will be a demand for it, some Makefile rule
bootstrapping debian/ directory could be devised.
