Willy Tarreau c222cb8389 MINOR: vecpair: add necessary functions to use vecpairss from/to ring APIs
Many ring-based APIs need a tail and a head, with some extra assumption
that the user takes care of not filling the ring so that tail==head is
unambiguous. Vectors are particularly suited to this usage so here we
create 4 functions to create vectors representing free room or data
from a ring, as well as updating rings based on a pair of vectors that
represents either free space or data.
