Corey Farrell	c9c03998cc	Astobj2: Add ao2_weakproxy_ref_object function. This function allows code to run ao2_ref against the real object associated with a weakproxy. It is useful when all of the following conditions are true: * You have a pointer to weakproxy. * You do not have or need a pointer to the real object. * You need to ensure the real object exists and is not destroyed during a process. In this case it's wasteful to store a pointer to the real object just for the sake of releasing it later. Change-Id: I38a319b83314de75be74207a8771aab269bcca46	10 years ago

Astobj2: Add ao2_weakproxy_ref_object function.

This function allows code to run ao2_ref against the real
object associated with a weakproxy.  It is useful when
all of the following conditions are true:
* You have a pointer to weakproxy.
* You do not have or need a pointer to the real object.
* You need to ensure the real object exists and is not
  destroyed during a process.

In this case it's wasteful to store a pointer to the real
object just for the sake of releasing it later.

astobj2: Add support for weakproxy objects.

This implements "weak" references.  The weakproxy object is a real ao2 with
normal reference counting of its own.  When a weakproxy is pointed to a normal
object they hold references to each other.  The normal object is automatically
freed when a single reference remains (the weakproxy).  The weakproxy also
supports subscriptions that will notify callbacks when it does not point
to any real object.
