With this patch it will be possible to use nested event contexts with messaging_filtered_read_send/recv. Before this patchset only the one and only event context a messaging_context is initialized with is able to receive datagrams from the unix domain socket. So if you want to code a synchronous RPC-like operation using a nested event context, you will not see the reply, because the nested event context does not have the required tevent_fd's. Unfortunately, this patchset has to add some advanced array voodoo. The idea is that state->watches[] contains what we hand out with watch_new, and state->contexts contains references to the tevent_contexts. For every watch we need a tevent_fd in every event context, and the routines make sure that the arrays are properly maintained.
