Merged Boost library build system changes from the trunk.

Covers the following trunk revisions:

--- [78934] ---
Minor stylistic changes made to the boostcpp.jam Boost library build module - wrapped comments and some code lines to 80 characters, removed duplicate imports, ordered imports alphabetically, corrected comment & end-user message typos, removed redundant quoting & trimmed trailing spaces.

--- [78935] ---
Made Boost library build script's '--with-...' & '--without-...' parameter checking more strict so e.g. '--run--with--system' is not interpreted as one of those options.

--- [78936] ---
Minor stylistic changes.

--- [78937] ---
Boost library build system code cleanup - removed a non-existing 'explicit' target being declared as explicit.

--- [78938] ---
Corrected a syntax error in Boost library's build system that was preventing unversioned library targets from being staged or installed on Windows & Unix when versioned layout is used. Closes ticket #6027 (https://svn.boost.org/trac/boost/ticket/6027).

--- [78939] ---
Boost library build system code cleanup - refactored the make-unversioned-links() rule.

--- [79300] ---
--- [79301] ---
Disabled generating unversioned library targets on Windows & Unix with requested versioned layout as the Boost library build has been reported to fail with this code enabled for Boost library release 1.50. See related Boost library development mailing list thread at http://lists.boost.org/Archives/boost/2012/06/194312.php for more detailed information.

Merged more changes (bug fixes, especially hopefully fixing the VC++ test failure) from trunk

Merged bug fix from trunk

svn path=/branches/release/INSTALL; revision=79393
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).
