Boost and Python macros

[Michael Tindal]

Dear ac-archive maintainers,

 I apologize for sending these as a group, but they are all related to the 
same subject.  Most of the macros check for the existance of Boost libraries 
and determine the correct library names to use from a list of predefined 
names and --with-boost-* macros.  The AX_PYTHON macro is used to set up the 
build environment for the AX_BOOST_PYTHON test.  If there are alternative 
methods to set that up please let me know.  I hope others find my 
contributions useful.  I plan on writing some macros to test for Boost 
testing frameworks soon.

The macros have been tested under my system (Debian GNU/Linux unstable, boost 
installed via apt-get) but the provided --with options should allow enough 
robustness for all systems.  Only caveat right now is I don't know how to 
check for what threading flag to use on a compiler (these are my first M4 
macros), so -pthread is hardcoded in AX_BOOST_THREAD.

Thank you for your time,

Michael Tindal
