Changes 0.2 -> 0.3:

- Applied Jeremy's patch to make genser work with type
  long long introduced in linux 1.1.46.
- Made diagnostic messages a bit more informative, especially
  when the connection is made.
- Removed a memory leak in fslib.c. It forgot to free the
  group list in several places.
- Fixed a bug in changed protocol for notify_change. This affects
  userfs.o, so you have to use the new module.
- Implemented NOTIFY_TIME to make touch work.
- Cache inodes in the hierarchy above to make getwd() work. It relies
  on the inode numbers.
