OSX/buildsystem: prepare usage on OSX 10.10 - Yosemite
- important: requires cmake >= 2.8.12 to read minor version right,
aka older cmake rates 10.10 lower than 10.6 for example ! ( sigh )
Fixed linking OIIO on Windows.  The debug and optimized options need to be before each individual library in a list.
Fix T41284: The python ops log doesn't work.
Correct glitch in recent menu commit, click-drag locked menus
Correct cu->pathlen treated as a float
Cleanup: replace int cast with floorf when comparing time
Macros: prevent instantiation of args for type checks

also make CHECK_TYPE_INLINE more strict
