FUlly automate documentation building. This makes it so that all the library docs are generated in modular form. As in each library is auto discovered and built according to what the library says. This is for both the integrated docs and the per library standalone docs. This change accompanies the addition of "boostdoc" and "boostreleas" targets to all buildable library docs.

-# Note that when refering to libraries that use auto-index we must process all the way to
-# docbook before including here.  We must also ensure that auto-index uses it's own index
-# generation, otherwise we get one big index that's repeated in each library.  Xslt's index
-# generation is also so slow that it's impractical for a build this large (takes ~ 9 hrs
-# to build with just 3 indexed libraries).  Hence we refer to these libraries as for example:
-#
-# ../libs/interprocess/doc//standalone/<format>docbook
-#
-# Within each library that uses this, make sure that the boostbook target contains
-#
-# <format>docbook:<auto-index-internal>on
-#
-# And if boost.root is set, restrict it to local html builds using:
-#
-# <format>html:<xsl:param>boost.root=../../../..
-# <format>html:<xsl:param>boost.libraries=../../../../libs/libraries.htm
-#
-# Finally, in boost.xml we xi:include interproces.auto_index.docbook which is the final
-# post-index generation docbook, rather than interprocess.xml which is the pre-indexed boostbook.
