[PoC] Handle jdt:// URIs

[kmARC]

eclipse.jdt.ls can retrieve definitions for symbols located in jar files.

Example:

import javax.jms.JMSException;

In a maven project, when cursor is on JMSExc|eption, :LspDefinition would reply with the following, including exact source file name and line/column location:

{
  "uri": "jdt://contents/geronimo-jms_1.1_spec-1.1.1.jar/javax.jms/JMSException.class?=java-engine-main/%5C/Users%5C/MYUSER%5C/.m2%5C/repository%5C/org%5C/apache%5C/geronimo%5C/specs%5C/geronimo-jms_1.1_spec%5C/1.1.1%5C/geronimo-jms_1.1_spec-1.1.1.jar=/maven.pomderived=/true=/=/maven.pomderived=/true=/=/maven.groupId=/org.apache.geronimo.specs=/=/maven.artifactId=/geronimo-jms_1.1_spec=/=/maven.version=/1.1.1=/=/maven.scope=/compile=/%3Cjavax.jms(JMSException.class",
  "range": {
    "end": {
      "character": 25,
      "line": 30
    },
    "start": {
      "character": 13,
      "line": 30
    }
  }
}

The "uri" string contains the location of the jar file, and within it the full of the JMSException.java file.

This patch converts this "uri" string into the following:

zipfile:///Users/MYUSER/.m2/repository/org/apache/geronimo/specs/geronimo-jms_1.1_spec/1.1.1/geroni
mo-jms_1.1_spec-1.1.1-sources.jar::javax/jms/JMSException.java

The zipfile://<path>.jar::<path> format is understood by vim and therefore it can open the definition.

Note that this is tested with a maven project, after dependency:sources downloaded the -sources.jar files for the otherwise binary dependencies.

---

Now this is clearly a proof-of-concept and not something I'd consider to be merged. However it worksforme and would be nice if vim-lsp's s:lsp_location_item_to_vim function could handle othe "proprietary" URI specifiers, including jdt://.
