This change introduces a new method in ConnManager that allows the
various implementations to optionally override it and specify
custom bounds query used for calculating splits during free form
query based imports.

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 removes the ShimLoader and various Shim classes such as CDH3Shim

Hive allows the use of keywords as column and table names as long as they are
escaped using back-ticks. This change makes Sqoop always escape table and
column names using back-ticks thereby allowing Sqoop to work with Hive tables
that use keywords for either the table name or column names.

The TextSplitter implementation used when creating splits on top
of String based columns, has a bug in its logic which causes
the bounds for splits to be created incorrectly. This results
in the import of duplicate data. This change fixes the TextSplitter

This change modifies the ClassWriter implementation to provide
support for interpeting empty strings as NULL values for datatypes
other than String. For String datatype, an explicit string 'null'
is interpreted as NULL value and empty string is not. This is
because certain databases distinguish between NULL and empty
strings.
The clone implementation generated by ClassWriter has also been
modified to make it more defensive against the presence of NULL
values.
