Files with hash functions inside lib/ were added in two separate
commits. Using master version.
Merged sysdep/unix/main.* and sysdep/unix/main_* to include changes from
both branches.
The old linked list implementation used some wild typecasts and required
GCC option -fno-strict-aliasing to work properly. This patch fixes that.
However, we still keep the option due to other potential problems.

A lib/list.h had circular dependency through include nest/bird.h
nest/bird.h requires lib/birdlib.h
lib/birdlib.h requires timer.h
timer.h requires lib/resource.h
lib/resource.h requires lib/list.h
