Improve the reading back of objects committed to the journal.

Implement a cache of memory-mapped log files so that when multiple objects
are requested we can re-use the mapping.  Make log files fixed sizes (call
ftruncate when opening the log file) so the entire thing can be memory
mapped at the start.
