[Devel] avpops.c fixup_write_avp

[Juha Heinanen]

i started implementing allow_uri function and read how avpops module
parses pseudo variables.  in avpops.c fixup_write_avp function i noticed
that presence of domain or username suffix is stored in local flags
variable, but it is not used anywhere.  should flags variable be xored
to flags given as argument to avpops_parse_pvar:

	ap = avpops_parse_pvar(s, XL_THROW_ERROR|XL_DISABLE_COLORS);
