Fix memory leaks during "tail -r" of an irregular file
* Rewrite r_buf to use standard tail queues instead of a hand-rolled
circular linked list. Free dynamic allocations when done.
* Remove an optimization for the case where the file is a multiple of 128KB
in size and there is a scarcity of memory.
* Add ATF tests for "tail -r" and its variants.
