MINOR: sink/api: pass explicit maxlen parameter to sink_write()

sink_write() currently relies on sink->maxlen to know when to stop
writing a given payload.

But it could be useful to pass a smaller, explicit value to sink_write()
to stop before the ring maxlen, for instance if the ring is shared between
multiple feeders.

sink_write() now takes an optional maxlen parameter:
  if maxlen is > 0, then sink_write will stop writing at maxlen if maxlen
  is smaller than ring->maxlen, else only ring->maxlen will be considered.

[for haproxy <= 2.7, patch must be applied by hand: that is:
__sink_write() and sink_write() should be patched to take maxlen into
account and function calls to sink_write() should use 0 as second argument
to keep original behavior]
