ACCUMULO-2381 Remove dangerous, broken utility

  Removes AddFilesWithMissingEntries utility, which does not support volumes,
  does not properly work with the root table, assumes the list of files fit in
  RAM, and does not satisfy a clear recovery use case for re-integrating
  abandoned files into the metadata table.
ACCUMULO-3352 Propagate bulk import errors to client

  Provide a better message in case of failures in bulk import, and propagate
  those errors to the client, rather than swallow them on the server side, and
  forcing the client to wait indefinitely.
ACCUMULO-3126 Fix malformed package-info.java

  Place javadoc above package declaration.
ACCUMULO-3172 Remove -dirty flag on releases

  Changes mavanagaiata plugin to stop incorrectly marking hashes as '-dirty'
  when using maven-release-plugin to create releases.
ACCUMULO-3437 Stricter thrift version checking

  Make Accumulo 1.5.x explicitly check for Thrift 0.9.0, not just 0.9.
