Review Request: 8005879: Add -DMAC_OS_X_VERSION_MAX_ALLOWED=1070 to builds on Mac

[Erik Joelsson]

Here are a series of patches that adds the following to all native 
compile lines on macosx:

-DMAC_OS_X_VERSION_MAX_ALLOWED=1070 -DMAC_OS_X_VERSION_MIN_REQUIRED=1070

This is needed to ensure that no macosx APIs newer than version 10.7 are 
used, and will cause compile time errors if they are.

Normally we would just lock down the build platform to avoid such 
problems, but in this case we can't. Newer mac hardware is not 
compatible with the older OS versions, forcing us to use newer OS 
versions on our build systems.

The hotspot changes will work independent of the rest and can go through 
rt as usual. The rest will go into build.

If a developer feels the need to disable this feature, the make variable 
MACOSX_REQUIRED_VERSION can be set to a different version (ex 1080) on 
the make command line.
