  ipropd-slave: don't send I_HAVE in response to AYT

ipropd-master sends AYT messages often as a result of a possibly-
transient error, but if the slave responds to such an AYT with I_HAVE,
then the same code path that failed will be executed on the master, and
if the error wasn't transient then we'll loop hard.  So don't send an
I_HAVE in response to an AYT.

  Log Message:
  -----------
  ipropd-master: use async I/O

If a slave is slow to consume what the master sends it, the master can
block and all iprop operations with it.

With minimal effort we make the master async oriented.

  Log Message:
  -----------
  Refactor send_diffs making it progressive

When a slave is many diffs behind, send these in batches of up to
50, then handle other slaves.

This also implements a fast-path that makes incremental diffs faster
when the log has not rolled over.

Related code cleanup.
