Lee Hinman 482843e27b Fix build to run correctly on FreeBSD
This adds the required changes/checks so that the build can run on
FreeBSD.

There are a few things that differ between FreeBSD and Linux:

- CPU probes return -1 for CPU usage
- `hot_threads` cannot be supported on FreeBSD

From OpenJDK's `os_bsd.cpp`:

```c++
bool os::is_thread_cpu_time_supported() {
  #ifdef __APPLE__
  return true;
  #else
  return false;
  #endif
}
```

So this API now returns (for each FreeBSD node):

```
curl -s localhost:9200/_nodes/hot_threads
::: {Devil Hunter Gabriel}{q8OJnKCcQS6EB9fygU4R4g}{127.0.0.1}{127.0.0.1:9300}
   hot_threads is not supported on FreeBSD
```

- multicast fails in native `join` method - known bug:
  https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193246

Which causes:

```
1> Caused by: java.net.SocketException: Invalid argument
1>    at java.net.PlainDatagramSocketImpl.join(Native Method)
1>    at java.net.AbstractPlainDatagramSocketImpl.join(AbstractPlainDatagramSocketImpl.java:179)
1>    at java.net.MulticastSocket.joinGroup(MulticastSocket.java:323)
1>    at org.elasticsearch.plugin.discovery.multicast.MulticastChannel$Plain.buildMulticastSocket(MulticastChannel.java:309)
```

So these tests are skipped on FreeBSD.

Elasticsearch REST API JSON specification

This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.

Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.

Example for the "Create Index" API:

{
  "indices.create": {
    "documentation": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
    "methods": ["PUT", "POST"],
    "url": {
      "path": "/{index}",
      "paths": ["/{index}"],
      "parts": {
        "index": {
          "type" : "string",
          "required" : true,
          "description" : "The name of the index"
        }
      },
      "params": {
        "timeout": {
          "type" : "time",
          "description" : "Explicit operation timeout"
        }
      }
    },
    "body": {
      "description" : "The configuration for the index (`settings` and `mappings`)"
    }
  }
}

The specification contains:

  • The name of the API (indices.create), which usually corresponds to the client calls
  • Link to the documentation at http://elastic.co
  • List of HTTP methods for the endpoint
  • URL specification: path, parts, parameters
  • Whether body is allowed for the endpoint or not and its description

The methods and url.paths elements list all possible HTTP methods and URLs for the endpoint; it is the responsibility of the developer to use this information for a sensible API on the target platform.

Utilities

The repository contains some utilities in the utils directory:

  • The thor api:generate:spec will generate the basic JSON specification from Java source code
  • The thor api:generate:code generates Ruby source code and tests from the specs, and can be extended to generate assets in another programming language

Run bundle install and then thor list in the utils folder.

The full command to generate the api spec is:

thor api:spec:generate --output=myfolder --elasticsearch=/path/to/es
