Use the new HTTPCLIENT_O_RES_HTX flag when using the CLI httpclient with
--htx.
It allows to process directly the response in HTX, then the htx_dump()
function is used to display a debug output.
Example:
echo "httpclient --htx GET https://haproxy.org" | socat /tmp/haproxy.sock
htx=0x79fd72a2e200(size=16336,data=139,used=6,wrap=NO,flags=0x00000010,extra=0,first=0,head=0,tail=5,tail_addr=139,head_addr=0,end_addr=0)
[0] type=HTX_BLK_RES_SL - size=31 - addr=0 HTTP/2.0 301
[1] type=HTX_BLK_HDR - size=15 - addr=31 content-length: 0
[2] type=HTX_BLK_HDR - size=32 - addr=46 location: https://www.haproxy.org/
[3] type=HTX_BLK_HDR - size=25 - addr=78 alt-svc: h3=":443"; ma=3600
[4] type=HTX_BLK_HDR - size=35 - addr=103 set-cookie: served=2:TLSv1.3+TCP:IPv4
[5] type=HTX_BLK_EOH - size=1 - addr=138 <empty>
This patch split the httpclient code to prevent confusion between the
httpclient CLI command and the actual httpclient API.
Indeed there was a confusion between the flag used internally by the
CLI command, and the actual httpclient API.
hc_cli_* functions as well as HC_C_F_* defines were moved to
httpclient_cli.c.
