This patch implements a couple of converters to validate and extract tag value from a FIX (Financial Information eXchange) message. The validation consists in a few checks such as mandatory fields and checksum computation. The extraction can get any tag value based on a tag string or tag id. This patch requires the istend() function. Thus it depends on "MINOR: ist: Add istend() function to return a pointer to the end of the string". Reviewed and Fixed by Christopher Faulet <cfaulet@haproxy.com>
