Async: Add future<>::fallback_to

Reported by: viboes Owned by: viboes
Milestone: Boost 1.55.0 Component: thread
Version: Boost 1.54.0 Severity: Problem
Keywords: Cc:

Description

Quite often the user as a fall back value that should be used when the future has an exception.

This factory creates a new future that will fall back to the parameter if the source future will be ready with an exception. The following

  f.fallback_to(v);

is a shortcut for

  f.then([](future<T> f) {
    return f.get_or(v);
  });
