Subject: [PATCH] headers: Strictly don't allow NUL bytes
In the past (2015) this was allowed for some problematic sites. However Chromium also does not allow NUL bytes in either header names or values these days. So this should no longer be a problem.

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.
