PROTON-507: advertise 1/2 the configured idle timeout as per the spec

PROTON-489: Use reference counting for object management.

Each child object will keep a reference to its parent: Deliveries
reference Links, which reference their Sessions, which reference the
containing Connection.  This keeps the parent objects present until
all child objects have been released.

The transport work lists also reference count their members (Endpoints
and Deliveries).  This keeps freed objects around long enough to flush
their pending state prior to deleting them.

PROTON-445: Dynamic languages honor CMAKE_INSTALL_PREFIX

All languages are installed to $CMAKE_INSTALL_PREFIX/bindings/$LANG by
default.

If the ASK_ALL macro is set to 1 at the command line, then each
language is interrogated as to the location of where they will be
installed, and that path modified wit the install prefix.

Individual languages can be told to interrogate for the install path
with:

  ASK_[LANG]=1

Refactored messenger's I/O in such a way that it can be driven by an
external poll/epoll/select loop as described in PROTON-525. This
involved factoring a bunch of utility I/O code out of the driver and
into a more basic I/O interface (io.h and selector.h), as well as
introducing the pn_selectable_t interface.

PROTON-526: split the definitions in engine.h into separate "per object" files; also added use of doxygen grouping tags so that generated API docs better reflect the design of the API
