Description
-------

While tinkering with ConfBridge on an Asterisk setup with a limited set of modules installed, I ran into an error reported from ConfBridge that it couldn't create a bridge due to a failure to create a softmix bridge. Unfortunately, bridge_softmix itself didn't relay why it wasn't created.

Inspecting the code revealed there are three ways creation of a softmix bridge can fail:
 1. Memory allocation failure
 2. NULL returned from ast_timer_open
 3. Thread creation failure

1 and 3 are both unlikely and likely to output an error from their respective routines. Number 2, however, is silent if no timing module is loaded.

This patch adds a warning on that off nominal path.

A lot of folks run Asterisk without a timing source (for whatever reason), which means - since softmix bridges will be used a lot more and in more places in 12 than in the past - a WARNING here is pretty useful.
