RFC 9110 14.1.2: if the representation is shorter than the suffix-length,
the entire representation is used. range_error computed a negative first
byte position for bytes=-8 on a 7-byte body and answered 416. Clamp it
at 0, as #711 did before the range handling was reworked.

parse_port checked only the error code of from_chars, which stops at
the first non-digit, so http://host:80abc was accepted as port 80, and
a redirect Location with such a port was followed. RFC 3986 defines
port as *DIGIT. Require the whole string to be consumed, as #2590 does
for quality values.
parse_sse_line checked only the error code of from_chars, which accepts
a leading '-' and stops at the first non-digit, so retry: -1 made the
client reconnect without waiting and retry: 10s set 10 ms. The SSE spec
ignores a retry value that is not all ASCII digits.
