encode_path() sent '"', '<', '>', '\', '^', '`', '{', '|', '}', '['
and ']' raw, although RFC 3986 §3.3 doesn't allow them in a path.
Tomcat, Jetty and Undertow answer each of them with 400 by default, but
accept the percent-encoded form. It also stopped at an embedded NUL, so
"/a\0b" went out as "/a". Encode every byte outside pchar, keeping '/'
and '%' so that escapes pass through, and still encode '+', ',', ';'
and '\'' as before.
encode_request_target() now passes only the path to encode_path(). The
"http://host" of a target sent to a proxy and a CONNECT "host:port" are
sent as they are, so the brackets of an IPv6 host stay.
