Willy Tarreau 6e59cb5db1 MINOR: mux-h1: pass CO_RFL_READ_ONCE to the lower layers when relevant 
When we're in H1_MSG_RQBEFORE or H1_MSG_RPBEFORE, we know that the
first message is highly likely the only one and that it's pointless
to try to perform a second recvfrom() to complete a first partial
read. This is similar to what used to be done in the older I/O methods
with the CF_READ_DONTWAIT flag on the channel. So let's pass
CO_RFL_READ_ONCE to the transport layer during rcv_buf() in this case.

By doing so, in a test involving keep-alive connections with a non-null
client think time, we remove 20% of the recvfrom() calls, all of which
used to systematically fail. More precisely, we observe a drop from 5.0
recvfrom() per request with 60% failure to 4.0 per request with 50%
failure.
