Subject: MINOR: htx: Add 2 flags on the start-line to have more info about the uri
X-Git-Tag: v2.1-dev3~132

MINOR: htx: Add 2 flags on the start-line to have more info about the uri

The first flag, HTX_SL_F_HAS_AUTHORITY, is set when the uri contains an
authority. For the H1, it happens when a CONNECT request is received or when an
absolute uri is used. For the H2, it happens when the pseudo header ":authority"
is provided.

The second one, HTX_SL_F_NORMALIZED_URI, is set when the received uri is
represented as an absolute uri because of the protocol requirements. For now, it
is only used for h2 requests, when the pseudo headers :authority and :scheme are
found. Internally, the uri is represented as an absolute uri. This flag allows
us to make the difference between an absolute uri in h1 and h2.
