[Mesa-dev] [PATCH v2 1/8] egl: add dri2_egl_surface_free_outdated_buffers_and_update_size() helper (v2)

[Gwan-gyeong Mun]

To share common free outdated buffers and update size code.
This compares width and height arguments with current egl surface dimension,
if the compared surface dimension is differ, then it free local buffers and
updates dimension.

In preparation to adding of new platform which uses this helper.

v2: Fixes from Eric's review:
   a) Split out series of refactor for helpers to a separate series.
   b) Add the new helper function and use them to replace the old code in the
      same patch.
