This avoids hitting the hard wall for connections with non-compliant
peers that would be accumulating errors over long connections. We now
permit to recycle the connection early enough to reset the connection
counter.
This was tested artificially by adding this to h2c_frt_handle_headers():
h2c_report_glitch(h2c, 1, "new stream");
or this to h2_detach():
h2c_report_glitch(h2c, 1, "detaching");
and injecting using h2load -c 1 -n 1000 0:4445 on a config featuring
tune.h2.fe.glitches-threshold 1000:

The failures are due to h2load not supporting reconnection.
