tidwall d7dbdd1d92 Add tilde boolean operator
This commit adds the new tilde '~' operator, which when used will
convert a value to a boolean before comparison.

For example, using the following JSON:

    {
      "vals": [
        { "a": 1, "b": true },
        { "a": 2, "b": true },
        { "a": 3, "b": false },
        { "a": 4, "b": "0" },
        { "a": 5, "b": 0 },
        { "a": 6, "b": "1" },
        { "a": 7, "b": 1 }
        { "a": 8, "b": "true" },
        { "a": 9, "b": false }
        { "a": 10, "b": null }
        { "a": 11 }
      ]
    }

You can now query for all true(ish) values:

    vals.#(b==~true)#

Which returns:

    [1,2,6,7,8]

Or all false(ish) values:

    vals.#(b==~false)#

Which returns:

    [3,4,5,9,10,11]

The last value which was non-existent is treated as "false"

tidwall d6cb589fc4 Fix non-existent response from multires query on empty array
This commit fixes an issue where a multires query on an empty
array will result in a non-existent (empty string) result.

For example `Get("[]", "#(key=value)#").Raw` resulted in an
empty string. But, it should actually result in the empty
array `[]`.

tidwall 0360deb6d8 Added new modifiers
`@flatten` Flattens an array with child arrays.
  [1,[2],[3,4],[5,[6,7]]] -> [1,2,3,4,5,[6,7]]
The {"deep":true} arg can be provide for deep flattening.
  [1,[2],[3,4],[5,[6,7]]] -> [1,2,3,4,5,6,7]
The original json is returned when the json is not an array.

`@join` Joins multiple objects into a single object.
  [{"first":"Tom"},{"last":"Smith"}] -> {"first","Tom","last":"Smith"}
The arg can be "true" to specify that duplicate keys should be preserved.
  [{"first":"Tom","age":37},{"age":41}] -> {"first","Tom","age":37,"age":41}
Without preserved keys:
  [{"first":"Tom","age":37},{"age":41}] -> {"first","Tom","age":41}
The original json is returned when the json is not an object.

`@valid` Ensures that the json is valid before moving on. An
empty string is returned when the json is not valid, otherwise
it returns the original json.

Add @this modifier
This modifier returns the current element as-is and can be used
to retrieve the JSON document itself. It is equivalent to the `#/` JSON Pointer.

tidwall 1e964df7d9 Support subqueries
It's now possible to do a query like

  topology.instances.#(service_roles.#(=="one"))#.service_version

On a JSON document such as

  {
    "topology": {
      "instances": [{
        "service_version": "1.2.3",
        "service_roles": ["one", "two"]
      },{
        "service_version": "1.2.4",
        "service_roles": ["three", "four"]
      },{
        "service_version": "1.2.2",
        "service_roles": ["one"]
      }]
    }
  }

Resulting in

  ["1.2.3","1.2.2"]

tidwall 3b5bf6bb5e Added Subselectors
It now possible to select multiple independent paths and join
their results into a single JSON document.

For example, given the following JSON

    {
      "info": {
        "friends": [
          {"first": "Dale", "last": "Murphy", "age": 44},
          {"first": "Roger", "last": "Craig", "age": 68},
          {"first": "Jane", "last": "Murphy", "age": 47}
        ]
      }
    }

The path `[info.friends.0.first,info.friends.1.last]` returns

    ["Dale","Craig"]

Or path `{info.friends.0.first,info.friends.1.last}` returns

    {"first":"Dale","last":"Craig"}

You can also rename Object members such as

`{"alt1":info.friends.0.first,"alt2":info.friends.1.last}` returns

    {"alt1":"Dale","alt2":"Craig"}

Finally you can combine this with any GJSON component

`info.friends.[0.first,1.age]` returns

    ["Dale",68]

This feature was request by @errashe in issue #113.

tidwall 1ed2249f74 Added modifiers and path chaining
A modifier is a path component that performs custom processing on
the json.

Multiple paths can be "chained" together using the pipe character.
This is useful for getting results from a modified query.

See the README file for more information.

Josh Baker ba784d767a Fix string output for large integers
This fix makes calling String() on a JSON Number return the original value
as it was represented in the JSON document for signed and unsigned integers.
This ensures that very big (plus-53bit) integers are correctly returned.
Floating points maintain their previous behavior [-+]?[0-9]*\.?[0-9]*.

Josh Baker a2f35b522e Added support for JSON Lines
Added support for JSON Lines (http://jsonlines.org) using the `..` prefix.
Which when specified, treats the multi-lined document as an array.

For example:

```
{"name": "Gilbert", "age": 61}
{"name": "Alexa", "age": 34}
{"name": "May", "age": 57}
{"name": "Deloise", "age": 44}
```

```
..#                   >> 4
..1                   >> {"name": "Alexa", "age": 34}
..3                   >> {"name": "Deloise", "age": 44}
..#.name              >> ["Gilbert","Alexa","May","Deloise"]
..#[name="May"].age   >> 57
```
