Git: Make parser reentrant

The git parser was using a number of global static variables. Remove
them by introducing a parser state, which is passed down to the
call hierarchy.

Advantages:
1) Removes global variables and makes the parser (mostly) reentrant.
2) More flexible - e.g. when parsing samples, the parser can now
   access the dive to check if the cylinder number is valid.
3) Less weak typing through "void *".
