  configure.in: Do not patch libtool rpath handling
  Fixing the Red Hat packaging

For historic reasons (mainly compatbility with really old libtool), configure was
patching libtool to not use rpath in binaries. This breaks (among other things)
correct operation of "make check" since the test binaries may not be run with
the correct shared library version.

Current best practice as seen e.g. at http://wiki.debian.org/RpathIssue suggests
that this is no longer an issue, so I'm removing the code that patches libtool.

The patch was supposed to check that pipe writer sends messages
in atomic fashion. However, it prevented the user to read
half of a message and close the socket.

Since executing the timers might modify the source pollsets we have
to defer the initialisation until after the timers have executed.

Add signaler_sndbuf_size option to config.hpp which allows the user to
increase the size of the send buffer used by the signalling socketpair.

Implement random backoff for reconnection attempts using a primitive
pseudo-random generation to prevent reconnection storms.

Add wait_before_connect option to config.hpp to allow the user to enable
random delay even on initial connect. Default is false for low latency.
