tidwall 6ee9f877d6 Added Escape function
This commit adds the Escape function for escaping a path
component, making it possible to directly querying keys that have
special characters like dots.

```
json := `{
  "user":{
      "first.name": "Janet",
      "last.name": "Prichard"
    }
}`
user := gjson.Get(json, "user")
println(user.Get(gjson.Escape("first.name")).String())
println(user.Get(gjson.Escape("last.name")).String())
// Output:
// Janet
// Prichard
```

tidwall e8e87f2a00 Add @dig modifier for recursive descent searches
This commit adds the "@dig" modifier, which allows for searching
for values in deep or arbitrarily nested json documents

For example, using the following json:

```
{ "something": {
    "anything": {
      "abcdefg": {
          "finally": {
            "important": {
                "secret": "password"
            }
        }
      }
    }
  }
}
```

```
@dig:secret  ->  ["password"]
```

tidwall 8d2c36ffa4 Added new tilde types and fixed ~false
This commit fixes an issue with ~false where the it's value was
simply the opposite of ~true. Now ~false explicitly checks for
false-ish values.

Also added ~null and ~* for testing null-ish and non-existent
values.

This commit fixes an issue where non-modifier path components
such as '@hello' return 0 for the Result.Index value.

tidwall c3bb2c39ba Remove encoding/json dependency
The only purpose of using the built-in Go was to encode json
strings that had unicode or needed to escaped.

This commit adds the new function `AppendJSONString` which allows
for appending strings as their json representation to a byte
slice.

It's about 2x faster than using json.Marshal.

tidwall e4fc67c92a Added group modifier
The new "@group" modifier allows for grouping arrays of objects.

For example, using the "@group" modifier on the following json...

  {"id":["123","456","789"],"val":[2,1]}

will results in...

  [{"id":"123","val":2},{"id":"456","val":1},{"id":"789"}]

tidwall 6b6af2ad5e Added new static value character

tidwall 2c9fd2476a Added Path and Paths for getting the original path of a Result
This commit adds a two new functions of the Result type:

- Result.Path:  Returns the original path of a `Result` that was
                returned from a simple `Get` operation.
- Result.Paths: Returns the original paths of a `Result` that was
                returned from a `Get` operation with a query.

tidwall 35fa0d71c8 Added @keys and @values modifiers
The "@keys" and "@values" modifiers converts an object into an
array of its keys or values respectively.

Take this json for example:

{"first":"Tom","last":"Smith"}

@keys   -> ["first","last"]
@values -> ["Tom","Smith"]

This feature was requested in #161.

tidwall 77a57fda87 Limit the complexity of "like" queries that match on a pattern.
This commit adds the uses the MatchLimit function, which it the
same as Match but will limit the complexity of the input pattern.
This is to avoid long running matches, specifically to avoid ReDos
attacks from arbritary inputs.

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 `[]`.

new sliceHeader and stringHeader stuctures have been added with
the same layout expect that they intentionally expose the data
field as an unsafe.Pointer instead of a uintptr.

update Result.Bool to use golang bool parsing
golang has several tools that already parse boolean values in the standard library. 
Specifically strconv.ParseBool(string)
https://golang.org/pkg/strconv/#ParseBool
"ParseBool returns the boolean value represented by the string. It accepts 1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False. Any other value returns an error."

This change returns any matching ParseBool string to that boolean value, or if the string is not one of those values, the error being thrown, returns a false.

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.
