[boost] Header dependency analysis unavailable for 1.29.0

From: Beman Dawes (bdawes_at_[hidden])

For 1.29.0, the header dependency analysis has been marked "Sorry, not 
available at this time."

The problem is that headers dependencies have gotten completely 
out-of-hand. For example, two years ago in 1.18.0, type_traits.hpp had 
seven dependencies listed. One year ago, in 1.25.0, type_traits.hpp had 24 
dependencies. In 1.29.0, that has grown to 153 dependencies.  See below.

Multiply that by the number of boost headers that use type_traits.hpp (and 
other headers that now have a huge number of dependencies), and the current 
header dependency analysis becomes unusable because of great size.

Beyond that, I think we can easily get into a major public perception 
headache by letting header dependencies grow in an unbounded fashion.

Comments?
