ring: Consistently use size_t to specify ring size
The mm_len member of struct ring is of type size_t, but in the code paths leading to set it, unsigned int is used. In circumstances where unsigned int is 32 bit and size_t is 64 bit, this could lead to an integer overflow, which causes an improper ring size being mmap()'ed in mmap_ring_generic(). In order to prevent this, consistently use size_t to store the ring size, since this is also what mmap() takes as its `length' parameter. This now allows to specify ring sizes larger than 4 GiB for both netsniff-ng and trafgen (fixes #90).
