Improvement on the DFS cache algorithm

We also made enhancements on the DFS client's cache algorithm in order to avoid slashing on the cache.

In the original cache algorithm of DCE, small-sized files tend to be flushed when a large-sized file(data file) is accessed. In general the small files, i.e., user programs and so on, must take advantage of the cache. To improve the performance of a system with a cache mechanism, we introduced a new function that the DFS client limits the available cache size for a large-sized file. Then, the DFS client keeps the small files from being flushed out.
