e9db840480 py: Start implementing "struct" module. 
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.

8bc3516389 ffi: Implement ffivar.get()/set() methods. 
Done by introducing another factored out helper API in binary.c. This API
can be reused also by array and struct modules.
