Alan Somers cdb7a6fc42 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.
