SCHEMA-49. IntegrationTestStripValueRowFilter needs to close row scanner.

This commit modified IntegrationTestStripValueRowFilter to close a KijiRowScanner
it opens by virtue of calling KijiTableReader#getScanner.  This prevents the
regionserver of the hbase test cluster from later closing the scanner when the
associated table has already been deleted.  This prevents a nasty looking exception
from making it to the console while integration tests are running.

This change has been tested by running mvn clean install 10 times.  The exception
log message is now absent.
SCHEMA-48. Allows integration tests to embed a mini HBase and M/R cluster in-process.

This allows running a single test in a debugger without external setup.

SCHEMA-40. Add audience annotations to classes.

Adds audience annotations to all classes.
  see github.com/kijiproject/annotations
Marks as many classes as 'final' as possible.
Moved ZooKeeperLock and ZooKeeperLockFactory into HBaseSchemaTable.
Removed ColumnNameTranslator subclass used in a single test that
  would be hard to maintain with final APIs.
Move TestHBaseSchemaTable into the proper package.

SCHEMA-55. Move kiji-schema into a submodule.

Prepare for SCHEMA-52 (multiple Hadoop distro support) by
setting up KijiSchema as a multi-module build.

* Adds a kiji-schema-root top-level pom file.
* Moves all existing kiji-schema code to the kiji-schema/ module.
* Updates /bin/kiji to refer to new location for the KijiSchema
  package.
* Updates kiji-schema/pom.xml to refer to multi-module parent.
* Updates kiji-schema assembly release.xml to use top-level NOTICE,
  LICENSE, and README files.
* Adds clones of src/main/checkstyle so 'mvn verify' works at the
  top level.
SCHEMA-63. Implement service registry backend for tools.

Incorporates SCHEMA-64 (Migrate KijiSchema tools to service registry backend).

* Tools are no longer statically configured in the bin/kiji script. They
  are discovered using the kiji-delegation "Lookup" service.
* All tools must implement KijiTool and list themselves as providers in
  META-INF/services/org.kiji.schema.tools.KijiTool.

Implementation changes:
* Added dependency on kiji-delegation from KijiSchema.
* Added public API KijiToolLauncher to provide a universal main method for
  launching tools.
* KijiTool is now a simple public interface for all tools.
* The previous "KijiTool" abstract class is renamed "OpenedKijiTool."
  This and BaseTool remain as Framework-level APIs that extend KijiTool.
* KijiTools do not get run through ToolRunner. All tool main() methods are
  still provided for convenience, but they use KijiToolLauncher now.
* IntegrationHelper now uses KijiToolLauncher, not Hadoop's ToolRunner.
* Added a unit test for KijiToolLauncher.
* Added a 'help' tool (HelpTool) that dynamically locates tools and prints
  their names and descriptions.
* Cleaned up o.k.s.util.Resources to be thread safe and to provide an API
  to locate text-based resources.
* Verbose help text from src/main/scripts/kiji has been put in
  src/main/resources/.../HelpTool.envHelp.txt, for use by HelpTool.

SCHEMA-71. Close leaking scanners in tests.

IntegrationTestKijiTableOutputFormat opens scanner resources that are not
closed.

Related to this, our log4j.properties file on the test classpath was not
using the DEBUG level for classes that print c'tor stacktraces in leaking
finalizers.

Turning on the DEBUG level for all of org.kiji.schema is too noisy on stderr,
because of the KijiCreation/DeletionThreads. But we can selectively create
separate loggers used by the finalizer cleanup check code; these loggers
are now enabled in debug mode during tests.
SCHEMA-72. IntegrationTestHBaseTableKeyValueDatabase leaks an HTable.
SCHEMA-88. KijiClientTest should isolate test instances between classes.

Classes that had hard-coded instance names referring to fake-hbase instances
could interfere with tests that inherit from KijiClientTest. This change
ensures that tests inheriting from KijiClientTest get class-specific instance
names.
SCHEMA-89. Remove PII from test data.
SCHEMA-86. Use dependency injection for HBaseFactory.

SCHEMA-56. Add bridge API to KijiSchema build.
SCHEMA-57. Add CDH4 bridge implementation.
SCHEMA-58. Add Apache Hadoop 1.x bridge implementation.
SCHEMA-60. Add bridge API method implementations.

Implement bridge API methods necessary to satisfy compatibility
between CDH4 and Apache Hadoop 1.x.

Adds a SchemaPlatformBridge implementation based on Hadoop 1.x that
always volunteers to be chosen; this performs the most basic handling
of compatibility, so hopefully it provides a useful catch-all for
versions that slip through the cracks.
SCHEMA-60. Multiple platform profiles for KijiSchema.

KijiSchema can now be built against multiple Hadoop platforms.
By default, it is compiled against CDH4. You can select the
compilation & test platform by running:

  mvn clean install # default; selects cdh4
  mvn clean install -Dplatform=hadoop1

Via the bridge API, the resulting package will run against either
CDH4 or Apache Hadoop 1.x.
