egl_dri2: add support for Android

Add platform_android.c that supports _EGL_PLAFORM_ANDROID.  It works
with drm_gralloc, where back buffers of windows are backed by GEM
objects.

In Android a native window has a queue of back buffers allocated by the
server, through drm_gralloc.  For each frame, EGL needs to

  dequeue the next back buffer
  render to the buffer
  enqueue the buffer

After enqueuing, the buffer is no longer valid to EGL.  A window has no
depth buffer or other aux buffers.  They need to be allocated locally by
EGL.

auxiliary/os: add wrappers for mmap/munmap

The use of mmap() in winsys requires large file support.  Not all OSes
have LFS so a wrapper should be used.  In particular, os_mmap() should
call __mmap2() on Android.

mesa: Fix incorrect access parameter passed to MapBuffer

The code previously passed GL_DYNAMIC_DRAW for the access parameter.
By inspection, I believe that all drivers would treat this as
GL_READ_WRITE because it's not GL_READ_ONLY and it's not
GL_WRITE_ONLY.

It appears the i965 code wants GL_WRITE_ONLY (it's about to write a
bunch of data in, never read data), while the arrayelt code is
GL_READ_ONLY (just dereffed as arguments to CALL_Whatever*v).
