[PATCH libdrm] Update/fix the {copy,commit}-headers targets

[Emil Velikov]

As some headers do not reside in include/drm we need to tweak our rules, 
and exclude headers that shouldn't be distributed [XXX: clarify why ?].

To avoid the extra magic of diving into the kernel tree running `make 
headers_install', just sed out the only reason why we need it - __user.

Gents,
As one runs `make copy-headers' we get a massive diff stat (+1500/-800) 
and a handful of issues gets pointed out.
Please let me know of your prefered solution (regardless if one will get 
to it soon) and if we should consider it a blocker (B) or not (N).

Thanks
Emil

 - (N) Header license miss-match - omap, msm, exynos. Update the kernel 
ones ?

 - (N) Broken compat ioctls - exynos (and the UMS drivers) - using 
unsigned int as opposed to _u32/64. Considering they're 32bit only, we 
can get away with 'breaking' the ABI and using the proper ones ?

 - (N, keep local for now) C++ compat - libdrm has a hack/workaround 
(virtual is a keyword in C++), which I'd like us to upstream plus some 
extern C wrappers.

 - (?) Missing UMS symbols - see _DRM_GEM

 - (?) Non C89 compliant (see DRM_DRAWABLE_CLIPRECTS) - do we still 
want/need that ?

 - (B) Using include <drm/...> as opposed to include "..." - drm.h, 
nouveau_drm.h. Should be fixed in kernel.

 - (N) ABI 'break'
  + drm - struct drm_mode_get_connector extra pad
  + tegra - struct drm_tegra_gem_mmap extra pad

 - (B) API break
  + drm - missing DRM_MODE_OBJECT_*
  + nouveau - missing (gs)etparam - both structs and macros. everything 
else is fine/unused.
  + radeon - RADEON_TILING_R600_NO_SCANOUT, CIK_TILE_MODE_COLOR_2D* and 
CIK_TILE_MODE_DEPTH_STENCIL_2D_TILESPLIT_* - quick grep shows no users
  + omap - struct drm_omap_get_base, DRM_OMAP_GET_BASE + IOCTL

 - (N) (unneeded?) API additions - nouveau's DRM_IOCTL_NOUVEAU_GEM_* 

 - (N) __KERNEL__ condiditionals. Is it really an issue - sure if looks 
a bit spurious but that's about it.
