Correct a JavaScript exception for empty distributions
...
If you create a distribution but don't write to it, the mean of the
distribution is NaN - which Aeson encodes as `null`. Thus we have to
make sure that when working with the mean, we check for `null`.

Break out core metric tracking into a new package
...
The new package, ekg-core, contains the metrics store, modules for
defining metrics, and functions for sampling the metrics.
The counter naming is also changed to include a namespace part. For
example "myapp.requests".
Finally the JSON format has been changed to be more self-descriptive.

Fix memory leak in new counter implementation
...
Since we're allocating memory for use outside Haskell, we're
responsible for freeing it. Switched to ForeignPtr to automate this.

Improve scalability of counters a lot
...
Counters now scale orders of magnitudes better as the number of
writers to the same counter increases. Here's the results on our
current benchmark on a 6 core machine:
cores
1 6
before 1.87s 81.09s
after 0.11s 0.32s
Note how the very heavy contention gives a slowdown rather than a
speedup as the number of cores increases, but the new implementation
slows down much less than the old one and is also generally faster.

Remove conditional export of GC counter
...
Previously par_tot_bytes_copied was only exported if base-6.4 or later
was used to compile ekg. Now it's always exported and uses
parAvgBytesCopied (which has the same meaning as parTotBytesCopied) when
ekg is compiled against older versions of base.
