loader: introduce the loader util lib
All the various window system integration layers duplicate roughly the same code for figuring out device and driver name, pci-id's, etc. Which is sad. So extract it out into a loader util lib. v2 (Emil) * Separate the introduction of libloader from the code de-duplication. * Strip out non-pci devices support. * Add scons + Android build system support. * Add VISIBILITY_CFLAGS to avoid exporting the loader funcs. v3 (Emil) * PIPE_OS_ANDROID is undefined at this scope, use ANDROID * Make sure we define _EGL_NO_DRM when building only swrast Signed-off-by: Rob Clark <robclark@freedesktop.org> Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Rob Clark <robdclark@gmail.com> Reviewed-by: Kristian Høgsberg <krh@bitplanet.net> Reviewed-by: Ian Romanick <ian.d.romanick@intel.com>
