[libmicrohttpd] [PATCH 4/9] HTTP/2: fixed ignoring of a SETTINGS frame with one setting

[Sami Jawhar]

The payload of a SETTINGS frame is a multiple of six bytes, and the
frame decoder checks that. But the processing started only above six
bytes, so a client's first SETTINGS frame with exactly one setting was
acknowledged and otherwise ignored.
