Trailers are delivered to the application as headers via CLIENTWRITE_TRAILER, but unlike regular response headers they skipped the verify_header() checks, so a server could smuggle a nul byte (or stray CR) into a header reaching CURLOPT_HEADERFUNCTION and curl_easy_header(). Run each assembled trailer line through Curl_verify_header(), the same validation used for normal headers. Covered by the new test 2106. Closes #21896
