Gooseberry: Disable CUDA kernels from buildbot compilation

OpenVDB kernel caused increase stress on the registers, which is now causing
compiler to crash for quite some time now.

Don't have time to look into details now and would prefer if the branch devs
will look into this.

Disabling CUDA for now, building without it is better than bot building at
all anyway.

Merge branch 'master' into temp-ui-widget-refactor

Remove redundant draw call

Fix uninitialized usage of uiWidgetDrawBase

Merge branch 'master' into missing-libs

Merge branch 'master' into openvdb

Rename C++ file extensions.

This is to be more consistent with what is used in the OpenVDB library.
Also my OCD sense was tingling.

Cleanup: reduce scopes of 'using namespace' declarations.
