Subject: [PATCH] headers: Be more robust against invalid input when
parsing params
If you pass invalid input to a function such as soup_header_parse_param_list_strict()
it can cause an overflow if it decodes the input to UTF-8.
This should never happen with valid UTF-8 input which libsoup's client API
ensures, however it's server API does not currently.
