The SqoopRecord.toString() and SqoopRecord.toString(DelimiterSet) methods
always append an end-of-record delimiter. Sqoop uses its own OutputFormat
when rendering these to text files, so that the user's delimiters are
preserved.
Other users could use this OutputFormat when working with SqoopRecord
instances in their own MapReduce code, but it would also be nice to "play
nice" with TextOutputFormat in the event that the intent is
newline-terminated records.
This patch allows users to suppress end-of-record delimiter generation when
formatting records with toString.

The change will look for ToolPlugin definitions in the
sqoop.tool.plugins configuration entry, or conf/tools.d. Each
ToolPlugin returns a list of ToolDesc entries, which are then
registered with SqoopTool.register() before the user's arguments
are parsed. The user can then run 'sqoop <custom-tool> args...'
as if it were part of the natural Sqoop system.

This change introduces the ability to use a staging table for intermediate
storage during execution for regular export jobs in insert mode. This allows
all of exported data to first be populated in the staging table and then
inserted into the destination table in a single transaction. Thus if a failure
were to occur during export, it is less likely to corrupt the destination
table data. Moreover, the staging table is emptied before the export
job starts populating it, which ensures that re-running the job does not
require any special clean up.

This change allows Sqoop to load options from an options file. An
options file is specified using --options-file. All options that
are otherwise specified on the command line should be specified
in this file in the order they would otherwise appear on the command
line. Options files can contain empty lines and comments for
readability. More than one options file may be used for a single
tool invocation if so preferred. Leading and trailing spaces are
ignored unless they appear within single or double quotes. Quoted
options extending into multiple lines are not supported.

This change modifies the ClassWriter implementation to provide
support for interpeting empty strings as NULL values for datatypes

Some spurious warnings (and inconsequential warnings in test code)
have been disabled by src/test/findbugsExcludeFile.xml.

OracleManager now caches Connection instances for subsequent OracleManager
instances.
Refactored uses of ConnManager to call close() before discarding them.
This allows the Oracle JUnit tests to sleep less frequently to wait for Oracle
to reap closed server-side connection resources, improving Oracle test speed
by 50%.
Sleeping cannot be fully eliminated because MapReduce-side Connections are not
governed by this caching mechanism.
Also added some debugging advice re. this topic to OracleManagerTest's comment.

Uses CombineFileInputFormat to run exports over a target number
of mappers independent of the number of input files.

Adds tests for external large objects.
Refactored large object loading into the map() method from readFields().

Major refactoring of DataDrivenImportJob to support mysqldump in mappers.
ImportJobBase added below DataDrivenImportJob.
MySQLDumpImportJob added on top of ImportJobBase.
LocalMySQLManager -> renamed to -> DirectMySQLManager now just runs MysqldumpIJ.
MySQLDumpImportJob configures MySQLDumpMapper to run mysqldump instances on
multiple nodes and is split-aware (via MySQLDumpInputFormat).
TestImportJob works with new ImportJobBase framework.
Added test that imports a subset of columns in mysql imports.
