The bug: Maps/ACLs using the same file/id can mistakenly inherit
their flags from the last declared one.
i.e.
$ cat haproxy.conf
listen mylistener
mode http
bind 0.0.0.0:8080
acl myacl1 url -i -f mine.acl
acl myacl2 url -f mine.acl
acl myacl3 url -i -f mine.acl
redirect location / if myacl2
$ cat mine.acl
foobar
Shows an unexpected redirect for request 'GET /FOObAR HTTP/1.0\n\n'.
This fix should be backported on mainline branches v1.6 and v1.7.
