HTTP/3: client header validation.
A header with the name containing null, CR, LF, colon or uppercase characters,
is now considered an error. A header with the value containing null, CR or LF,
is also considered an error.
Also, header is considered invalid unless its name only contains lowercase
characters, digits, minus and optionally underscore. Such header can be
optionally ignored.
