1c169ac55e build.bash: handle missing git tags
The case of a git repo without any tags used to fail
with:

  fatal: No names found, cannot describe anything.

Now we continue, using "[no_tags_found]" as the
version string.

f6b1c680b3 nametransform: update comment & simplify tests
The comment still mentioned CBC, which has been removed
a long time ago.

The test definition can be rewritten using slice literals,
saving sume stuttering.

8f5c2a613d Prefer Go stdlib aes-gcm on arm64 with aes instructions
We used to prefer openssl in this situation, which
used to make sense, but now Go gained an optimized
assembly implementation for aes-gcm on arm64 with
aes instructions:

2568518992 crossbuild.bash: set GOARM=7
From https://github.com/golang/go/wiki/GoArm :

  In cross compilation situations, it is recommended
  that you always set an appropriate GOARM value
  along with GOARCH.

The value seems to default to GOARM=5 if not set
during cross-compilation.

ca9e912a28 fusefrontend: drop xattr user namespace restriction
We used to restrict setting xattrs to the "user."
namespace. I don't see a real reason for this
anymore, and it causes trouble for users who are using
acls.

Tests will be added in the next commit.

9178aa1534 MANPAGE: describe how to unmount, and that default options are fine
Feedback received during the recent Go user group. If you haven't
used FUSE before, you don't know how to unmount, and it was not
described in the man page!

As for the options, there are many, and new users are intimidated
by it. State clearly that defaults are fine.

e4148028af fusefrontend: warn about missing diriv
The comment is outdated, at this point, we should
really not get any errors from ReadDirIVAt.

The change is best seen when running the fsck tests. Before:

  fsck: error opening dir "missing_diriv": 2=no such file or directory

After:

  OpenDir "K2m0E6qzIfoLkVZJanoUiQ": could not read gocryptfs.diriv: no such file or directory
  fsck: error opening dir "missing_diriv": 5=input/output error

See https://github.com/rfjakob/gocryptfs/issues/403 , where
the extra info would have been helpful.

93939961f5 fusefrontend: don't return EIO on directory with corrupt file names
This was meant as a way to inform the user that
something is very wrong, however, users are hitting
the condition on MacOS due to ".DS_Store" files, and
also on NFS due to ".nfsXXX" files.

Drop the whole thing as it seems to cause more pain
than gain.
