[boost] ublas use of NDEBUG considered harmful

I believe ublas should not coopt the NDEBUG symbol used by <assert.h>, but 
should define it's own symbol instead.

The user should be able to set a symbol, e.g., UBLAS_NDEBUG:

Just add this to ublas config.h:

#ifdef NDEBUG
#  define UBLAS_NDEBUG
#endif

Now replace all previous use of NDEBUG in ublas with UBLAS_NDEBUG.  This will 
have the desired effect that asserting NDEBUG will optimize ublas, but 
without disabling assertions - these should be orthogonal.
