Subject: More texture image changes. 1. Added
 ctx->Driver.ChooseTextureFormat() function.  Examines user's   
 internalFormat, format, type params and returns a gl_texture_format. 2.
 _mesa_store_teximage[123]d() calls ctx->Driver.ChooseTextureFormat(),   
 allocates storage and transfers the image into the desired format. 3.
 _mesa_transfer_teximage() now takes a gl_texture_format to describe    the
 destination format.  Any combination of input format/type and    output
 gl_texture_format is accepted.  Uses optimized _mesa_convert_-   
 texsubimage[123]d() functions when possible. 3. DRI driver's TexImage[123]D
 functions should be a lot simpler now.
