upgrade to 1.31.0

 - builds the most recent boost version (1.31.0)
 - respects PTHREAD_{CFLAGS, LIBS} (credits for the PTHREAD_LIBS part
   go to Craig Rodrigues <rodrigc@crodrigues.org>)
 - builds all boost libraries
 - installs docs into DOCSDIR, and examples into EXAMPLESDIR (as
   before), but the hyperlinks to the example files are corrected (pls.
   report if you find some broken links)
 - has new various tunable options, such as
    o WITH_DEBUG
    o WITHOUT_THREAD
    o WITH_OPTIMIZED_CFLAGS
    o VERBOSE_BUILD
 - forced major numbers for shared libraries (everything defaults to
   .so.1, and is symlinked to .so)
 - installs the possible versions of the libraries (w/ or w/o
   debugging or threading support) with the same suffix- and prefix-less
   name, e.g. instead of libboost_filesystem-gcc-debug-s.so.1 (the gcc toolset,
   debugging info and single threaded) and
   libboost_filesystem-gcc-m.so.1 (gcc toolset, release version, multi
   threaded), there now is only libboost_filesystem.so.1.
