gsdx ogl:
* Separate state and shader compilation into separate function
* replace various hash_map by basic array
* Compact VertexScale and offset into a single vec4
* add the new option "ogl_vertex_subdata": subdata is faster on FGLRX, test are welcome on Nvidia drivers
    0 => use map/unmap
    1 => use subdata

replay: add "linux_replay" option and compute some nice stat (mean, standard deviation)

cmake: recreate shader header at build time
