st/mesa: completely rewrite state atoms

The goal is to do this in st_validate_state:
   while (dirty)
      atoms[u_bit_scan(&dirty)]->update(st);

That implies that atoms can't specify which flags they consume.
There is exactly one ST_NEW_* flag for each atom. (58 flags in total)

There are macros that combine multiple flags into one for easier use.

All _NEW_* flags are translated into ST_NEW_* flags in st_invalidate_state.
st/mesa doesn't keep the _NEW_* flags after that.

torcs is 2% faster between the previous patch and the end of this series.

v2: - add st_atom_list.h to Makefile.sources
