KUDU-1938 [java] Add support for VARCHAR pt 4
Adds support for VARCHAR type to the Java and Spark clients. The
kudu-client only changes would break tests in kudu-spark and kudu-backup
so this patch also incorporates changes in these subprojects.

KUDU-1938 Add non-copy VARCHAR setters pt 3
Apache Impala uses KuduPartialRow API to determine which partition a row
will be inserted to distribute the data between executors optimally.
For this purpose the copy is unnecessary and it should be fast. This
commit adds NoCopyUnsafe variants for this purpose which expect the data
to already be truncated (which it is in Impala's case) and only check
that the value's length is lower than the highest possible upper bound:
val.size() < max_length*4 bytes (the maximum size of an UTF8 character)
to avoid having to count each character manually.

KUDU-1938 Add support for VARCHAR pt 1
Introduces the VARCHAR data type to the server. Follow up commits will
add integration to the clients. The VARCHAR type is parameterized with a
length column type attribute similar to DECIMAL's scale and precision.
Internally it's stored as BINARY.
The maximum length for VARCHAR is 65,535 characters. If a value longer
than the "n" is submitted for a VARCHAR(n) column the value is truncated
to "n" characters before persisting the data on the server side.
The maximum length was chosen for compatibility reasons. Apache Impala
has a maximum length of 65,535 *bytes* for VARCHAR and major RDBMSs I
checked also have a similar limits either in characters or bytes, mostly
configurable.

> Priority: Major
> Labels: limitations, roadmap-candidate
> Fix For: 1.12.0

>
> VARCHAR is currently not supported by Kudu. This is functionality that
> currently exists in Impala. Some client applications convert STRING to 32K
> bytes which causes performance issues so they need the VARCHAR support in
> order to integrate well with Kudu.
