mesa: Handle uninitialized textures like other textures in get_tex_level_parameter_image

Instead of catching the special case early, handle it by constructing a
fake gl_texture_image that will cause the values required by the OpenGL
4.0 spec to be returned.

Previously, calling

    glGenTextures(1, &t);
    glBindTexture(GL_TEXTURE_2D, t);
    glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, 0xDEADBEEF, &value);

would not generate an error.

android: gallium/freedreno: add preliminary build

For all the people interested in testing the freedreno driver on
their Android devices. The next commit will hook these up within
the libEGL driver (via the gallium-egl backend).

There may be some rough edges but those can be sorted when a
willing builder/tester comes along.

v2:
 - s/freefreno/freedreno/. Spotted by Matt Turner.
 - Use the installed libdrm headers.

android: gallium/auxiliary: drop log2/log2f redefitions

Recent versions of bionic has picked up support for these functions,
leading to build issues due to the redefition of the symbols.

Note: wrapping things in #ifdef does not cut it :\

Identical patch is available in chromium, android-x86 and perhaps other
projects.

android: drop HAL_PIXEL_FORMAT_RGBA_{5551,4444}

Upstream Android (system/core) has dropped these formats with commit
6bac41f1bf9(get rid of HAL pixelformats 5551 and 4444) yet does not
mention why.

These formats never really worked so we're safe to drop them as well.

radeon/compute: Fix reported values for MAX_GLOBAL_SIZE and MAX_MEM_ALLOC_SIZE

There is a hard limit in older kernels of 256 MB for buffer allocations,
so report this value as MAX_MEM_ALLOC_SIZE and adjust MAX_GLOBAL_SIZE
to statisfy requirements of OpenCL.
