When the expression called in "set-var" uses argments that require late
resolution, the context must be set. At the moment, any unknown argument
is misleadingly reported as "ACL":
frontend f
bind :8080
mode http
http-request set-var(proc.a) be_conn(foo)
parsing [b1.cfg:4]: unable to find backend 'foo' referenced in arg 1 \
of ACL keyword 'be_conn' in proxy 'f'.
Once the context is properly set, it now says the truth:
parsing [b1.cfg:8]: unable to find backend 'foo' referenced in arg 1 \
of sample fetch keyword 'be_conn' in http-request expression in proxy 'f'.
This may be backported but is not really important. If so, the preceeding
patches "BUG/MINOR: vars: improve accuracy of the rules used to check
expression validity" and "MINOR: sample: add missing ARGC_ entries" must
be backported as well.
