Add support for the C99 function 'log2()' which is newly needed by 'gtk2_ardour/tempo_lines.cc' (but isn't available from MSVC).
These changes are MSVC specific and shouldn't affect the other builds.
(incidentally, libpbd already offers a function called 'fast_log2()'. Not sure if that could have been used instead...)
