xattr.h: expose string defines to userspace
af4f136056c9 ("security: move LSM xattrnames to xattr.h") moved the
XATTR_CAPS_SUFFIX define from capability.h to xattr.h. This makes sense
except it was previously exports to userspace but xattr.h does not export
it to userspace. This patch exports these headers to userspace to fix the
ABI regression.
There is some slight possibility that this will cause problems in other
applications which used these #defines differently (wrongly) and I could
JUST export the capabilities xattr name that we broke. Does anyonehave an
idea how exposing these headers could cause a problem?
Below is what is being exposed to userspace, included here since it isn't
clear exactly what is going to be made available from the patch.
