GEODE-2578: Remove 64 KiB limit on query strings.
- Remove artificial cap of 65535 for query string
length by using 32 bits for the length of query
strings in DataOutput::writeFullUTF().
- Rename parameter to TcrMessage::writeStringPart()
whose name is misleading due to copy-and-paste.
- Add three unit tests for query-related messages:
* testConstructorEXECUTECQ_MSG_TYPE
* testConstructorWithGinormousQueryEXECUTECQ_MSG_TYPE
* testConstructorEXECUTECQ_WITH_IR_MSG_TYPE
- Fix the cursor advance tests to not depend on
specific values for buffer length and not to
test remaining buffer length.

> Project: Geode
> Issue Type: Bug
> Components: native client
> Reporter: Michael Dodge
> Assignee: Michael Dodge
>
> The serialization of query strings uses a 16-bit unsigned integer to
> represent the length of the query string. Query strings with more than 65535
> characters are silently truncated. Use of a 32-bit unsigned integer to
> represent the length would greatly increase the size of query strings that
> may be used.
