MINOR: htx: Add a function to retrieve the HTTP version from a start-line

htx_sl_vsn() function can now be used to retrieve the ist string
representing the HTTP version from a start-line passed as parameter. This
function takes care to return the right part of the start-line, depending on
its type (request or response).
