Review request for hbase, Dhruba Borthakur, Michael Stack, and Mikhail Bautin.
Changes
-------
Renamed setters to be prefixed with: forTestsOnly_
(I'm still opting to keep it this way because I know that the next set of tests
I write for the compressed cache stuff is going to want to do the same thing)
Summary
-------
Adds a new test that fails w/o this fix and changes the naming scheme for
storefiles to use UUID instead of random longs as ascii.
The big change is that the name of the tmp file used when flushing and
compacting is the same name (but different dir) when moved in place. This
makes it so block names are consistent for COW.
This addresses bug HBASE-3417.

Testing
-------
TestFromClientSide and TestCacheOnWrite both working
Thanks,

> Currently the block names used in the block cache are built using the
> filesystem path. However, for cache on write, the path is a temporary output
> file.
> The original COW patch actually made some modifications to block naming stuff
> to make it more consistent but did not do enough. Should add a separate
> method somewhere for generating block names using some more easily mocked
> scheme (rather than just raw path as we generate a random unique file name
> twice, once for tmp and then again when moved into place).
