Introduce flexarray_append_pair: a simple syntactic sugar to add a pair of pointers to a flexarray, very useful when adding pairs of strings to xenstore. Replace flexarray_vappend calls (and one pair of flexarray_append) with flexarray_append_pair calls when dealing with flexarrays that are going to be used with libxl__xs_kvs_of_flexarray: NULL is a valid pointer value in these cases while flexarray_vappend uses NULL as vargs terminator, so the old code is buggy.
