Marked some expected failures for release regression test compilers. Renamed a local function internal template parameter from Bn to Bindn (because B0 is defined as a macro from a Linux header to represent a baudrate). Added itdentity_type.hpp to utility.hpp. Made reference data members of LocalFunction Addable static (because they are not set in the constructor).
Update Jamfiles and build scripts for PDF generation.
Set local_function image DPI's for better PDF builds.
Merge documentation build fix from trunk.
Fixing broken doc links.
Fixing broken doc links (removing mixed capitals from HTML file names).
Merge changes from trunk:

Fix PDF install rule so that it's explicit and automatically invokes a PDF build when specified on the command line.
So "bjam pdfinstall" will now build and install the PDF to the current directory.
This works around some problems that the previous versions had if the user did not have an FO processor installed (basically Daniel James was unable to build the HTML docs for the distribution if the pdfinstall rule was implicit).
Merge deprecated macro change for Boost.LocalFunction to release; no functionality change
