gles-3.0: Add minmax test (v3)

This is the first GLES3 test.

Tested against Mesa, branch gles3, commit 5612c08 "egl/dri2: Add plumbing
for EGL_OPENGL_ES3_BIT_KHR", with Intel Sandybridge.  All testcases pass
except:

  token                            min          actual
  GL_MAX_ELEMENT_INDEX             16777215     16384
  GL_MAX_FRAGMENT_INPUT_COMONENTS        60      9999
  GL_MIN_PROGRAM_TEXEL_OFFSET            -8      9999
  GL_MAX_PROGRAM_TEXEL_OFFSET             7      9999

Currently, all.tests contains the GL tests, all_es1.tests contains the
GLES1 tests, and all_es2.tests contains the GLES2 tests. This is the first
GLES3 test, so I added the file all_es3.tests. We should really clean that
up and put all tests in all.tests.

v2: Add tests for the following, for Anholt,
  GL_MIN_VIEWPORT_DIMENSIONS
  GL_NUM_*_BINARY_FORMATS
  GL_MAX_SERVER_WAIT_TIMEOUT

v3: If a value is listed as unsigned in the spec, then test it as
    unsigned. Fixes GL_MAX_SERVER_WAIT_TIMEOUT.
