[core] Fix the build post the #461 merge.

Add a new and optional measurement type called "RAW" which outputs every dat apoint of a run.

Add single definition of status codes

[jdbc] JDBC module fields fix

1. Use LinkedList rather than ArrayList for the measurement array in RAW. Update size estimation in documentation in workload_template.

2. Add a new composite measurement type which combines HdrHistogram and RAW.

3. Allow user to optionally disable output of summary stats from the raw measurement class.

Replaces numeric status codes with a canonical set of Status objects,
each with a short name and description.
Bindings with more specific errors (e.g., timeouts) return additional
statuses.

This changes the default output from messages like:

   [UPDATE], Return=0, 511

To:

   [UPDATE], Return=OK, 511

[jdbc] added LIMIT to JDBC scan operation

Add posix compatibility to distribution.

[accumulo] README.md for the Accumulo Binding.

[cassandra] Checkstyle updates for the Cassandra bindings (cassandra …

[aerospike] Checkstyle updates for Aerospike.

[accumulo] Checkstyle cleanup and enforcement for the Accumulo binding.

This will ensure record ordering my the primary key.

Now properly enforcing a scan of the given number of documents in the
scan operation using the LIMIT modifier in the cached statement.

Fixes #171.

* Added a package-info.java.
* Added JavaDoc for the binding's DB implementation.

Again, a lot of whitespace changes and the normal checkstyle type errors.

2 items of note:

1. Deprecated QueueElement since it is not used.
2. Moved some of the exception handling to common locations to remove
   empty catch blocks.

Add a new and optional measurement type called "RAW" which outputs every dat apoint of a run.

Raw datapoint output is quite useful and important for two reasons:
 1) Allows the user to do more thorough statistical analysis on the complete set of the data.
 2) Using timestamps that are logged with raw data points, it becomes much easier to investigate and correlate latency outliers at the backend service.
