8369432: Add Support for JDBC 4.5 MR

[LanceAndersen]

This PR adds support for the upcoming JDBC 4.5 MR which provides the following updates to the JDBC specification:

• Deprecate SQLPermission for removal
• Enhance the Blob/Clob/Array/SQLXML/NClob interfaces to extend/support AutoClosable
• Add the SQL types DECFLOAT, JSON to Types.Java and JDBCType.java
• Add the quoted identifier methods that were added previously to the Statement interface in JDK 9 to the Connection interface
  • It is the exact same verbiage & default methods used when these methods were added to the Statement interface
• Clarify the Timestamp::hashCode method which incorrectly indicates that nanos are not used when calculating the hash

Tiers 1-3 have been run

Pattern::matches invokes Pattern::compile and String::matches invokes Pattern::matches so did not see the benefit when we added the methods originally in JDK 9

Yeah, it just seemed String:matches would be less verbose. I then noticed Roger raising related suggestions about precomplication, which is why I removed my comment from the PR since it seemed no longer relevant.

Ah that explains why I did not see your comment...

[RogerRiggs]

Looks good.

[AlanBateman]

The title is consistent with the other updates but I'm wondering why it hasn't been switched to "module java.sql".

[AlanBateman]

I through went several iterations of the API docs with Lance, all good there. I have not reviewed SQLUtils or the tests.
