Rename intmath.h to intmath.hh

clean up the formatting
make things use templates since this is C++ now.

base/circlebuf.cc:
base/intmath.cc:
base/intmath.hh:
base/range.hh:
base/remote_gdb.cc:
base/statistics.cc:
base/str.cc:
    intmath.h -> intmath.hh
base/intmath.hh:
    Make this more like C++ by templatizing these functions

--HG--
rename : base/intmath.h => base/intmath.hh
