* Strbuf + Ustrbuf: Added eina_(u)strbuf_manage_new. This lets us
take a string and use it as the string buffer instead of copying
and allocating.
+
+2011-09-15 Cedric Bail

+ * Add eina_xattr_ls, eina_xattr_get, eina_xattr_set, eina_xattr_string_set,
+ eina_xattr_string_get, eina_xattr_double_set, eina_xattr_double_get,
+ eina_xattr_int_set, eina_xattr_int_get.
