Christopher Faulet c17c31c822 BUG/MEDIUM: mux-h1: Don't wake h1s if mux is blocked on lack of output buffer 
After sending some data, we try to wake the H1 stream to resume data
processing at the stream level, except if the output buffer is still
full. However we must also be sure the mux is not blocked because of an
allocation failure on this buffer. Otherwise, it may lead to a ping-pong
loop between the stream and the mux to send more data with an unallocated
output buffer.

Note there is a mechanism to queue buffers allocations when a failure
happens. However this mechanism is totally broken since the filters were
introducted in HAProxy 1.7. And it is worse now with the multiplexers. So
this patch fixes a possible loop needlessly consuming all the CPU. But
buffer allocation failures must remain pretty rare.

This patch must be backported as far as 2.0.
