Also added Mac version of the same fix, and corrected the warning message in the Linux version that was already there.

VWR-20673 (SNOW-743) FIXED Compiler warning: 'region_access' may be used uninitialized in this function

VWR-20671 (SNOW-514) FIXED Protection on LLInstanceTracker base in LLNameListCtrl needs to be public for gcc >4.1

VWR-20670 (SNOW-506) FIXED Protection on LLInstanceTracker base in LLEventTimer needs to be public for gcc >4.1

No longer need the "build_server" settings, since "build.sh" no longer has that code. Mainly rebuild to clean up the result page.

Reintroduce check for LLKDU source after downloading the prebuilt lib, to avoid adding a build dependency on it.

Required because indra/cmake/Variables.cmake uses indra/Server.cmake as a flag to indicate this is an internal build, and set INSTALL_PROPRIETARY to download and install pre-built LLKDU, FMOD and Quicktime.

We need a better way of doing that, but this should get things going for now.

Set to viewergpl for now.
