i.e. prefix the keys with the namespace, so it is ns.key like on
linux.
still only dealing with the "user" namespace, like before.
in the "system" namespaces there are ACLs (we deal with them via the acl
api, so no problem) and stuff from pnfsd (not sure what exactly).
this change is needed because FreeBSD's FUSE code expects the xattr
keys to be in that format.
it is also needed for cross-platform data exchange, so e.g. if one wants to:
- create archive on linux, extract on freebsd - with "user.xxx" xattrs.
- or vice versa.
archives made with older borg versions on freebsd will still extract correctly
on freebsd (not on linux though) even though they do not have the
namespace prefixes in the archived metadata (it will be interpreted in
same way as if they were prefixed by "user." as we do not support any
other namespace anyway).

"default_permissions" is now enforced by borg by default to let the
kernel check uid/gid/mode based permissions.
"ignore_permissions" can be given to not enforce "default_permissions".
note: man mount.fuse explicitly tells about the security issue:
default_permissions
By default FUSE doesn't check file access permissions, ...
This option enables permission checking, restricting access
based on file mode.
This option is usually useful together with the allow_other
mount option.
We consider this a pitfall waiting for someone to fall into and this is
why we chose to change the default behaviour for borg.
thanks to AJ Jordan @strugee for finding this.
while using \\ gives a single backslash when using "borg help pattern"
on the shell, our rendered html docs did not show the single backslash
at all.
i was lazy do dig into that issue, so i just used the word "backslash".
:-)
keep "data" as is, use "d" for slices
so that the data.release() call is on the original memoryview and
also we can delete the last reference to a slice of it first.
in master branch, it was possible to do this via setup.py's
cythonize() calls, but we do not have them in 1.1.
thus, i modified the source files, setting the language level to 3,
which is supported since long in Cython (3str is only supported since
recently so might fail with older Cython versions).
Before this changeset, current Cython 0.29.x emitted a FutureWarning,
but still compiled. The next major release of Cython is said to emit
an error instead, so this changeset hopefully avoids the build breaking
after a Cython upgrade.
