[PATCH] libdrm: hide all private symbols

[Maarten Lankhorst]

Using -export-symbols-regex all private symbols are hidden, resulting in the following changes:

libkms: removes all driver specific exports
radeon: removes the bof_* exports
nouveau: removes the abi16_* exports
freedreno: remove the *kgsl_* and msm_* exports
intel: removes the drm_mm* exports
omap/exynos: unchanged as far as I can tell
