Pass VALUE_LENGTH directly instead of re-declaring it.

> Key: HBASE-10251

> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 0.98.0, 0.98.1, 0.99.0, 0.98.2
> Reporter: Aleksandr Shulman
> Assignee: Dima Spivak
> Labels: api_compatibility

> Observed:
> A couple of my client tests fail to compile against trunk because the method PerformanceEvaluation.generateValue was removed as part of HBASE-8496.
> This is an issue because it was used in a number of places, including unit tests. Since we did not explicitly label this API as private, it's ambiguous as to whether this could/should have been used by people writing apps against 0.96. If they used it, then they would be broken upon upgrade to 0.98 and trunk.
> Potential Solution:
> The method was renamed to generateData, but the logic is still the same. We can reintroduce it as deprecated in 0.98, as compat shim over generateData. The patch should be a few lines. We may also consider doing so in trunk, but I'd be just as fine with leaving it out.
> More generally, this raises the question about what other code is in this "grey-area", where it is public, is used outside of the package, but is not explicitly labeled with an AudienceInterface.
