b=2104

- make sure to clear all pointers when various structures are freed

- if mdc_close can't find the mdc_open_data, then it should expect the close
RPC to fail; if it doesn't, print a stern warning

- Adds replay-single test 32, testing both the case where the close() is the
RPC that detects the eviction (-EIO) and the case where the close() runs
afterwards (-ESTALE)
