This commit improves escape() performance by up to 15% with the
existing querystring-stringify benchmarks by reducing the number
of string concatentations. A potential deopt is also avoided by
making sure the index passed to charCodeAt() is within bounds.

Before this, v8 would deopt when an out of bounds `inIndex` would get
passed to charCodeAt(). charCodeAt() returns NaN in such cases, so we
directly emulate that behavior as well.
Also, calls to charCodeAt() for constant strings have been replaced
by the raw character codes and parser state is now stored as an
integer instead of a string. Both of these provide a slight
performance increase.

This commit improves parse() performance by ~20-200% with the various
querystring-parse benchmarks.
Some optimization strategies used in this commit include:
* Combining multiple searches (for '&', '=', and '+') on the same
string into a single loop
* Avoiding string.split()
* Minimizing creation of temporary strings
* Avoiding string decoding if no encoded bytes were found and the
default string decoder is being used

There was a very subtle change in behavior introduced with 27def4f
In the past if querystring.parse was given Infinity for maxKeys,
everything worked as expected.
Check to see is maxKeys is Infinity before forwarding the value to
String.prototype.split which causes this regression

There's no need to add extra logic for it, `String.prototype.split`
already has a `limit` argument. By using this argument we avoid keeping
the whole array in memory, and V8 doesn't have to process the entire
string.

With an indentation style of two spaces, it is not possible to indent
multiline variable declarations by four spaces. Instead, the var keyword
is used on every new line.
Use const instead of var where applicable for changed lines.

parse optimizations:
* Move try-catch to separate function to keep entire function from
being deoptimized.
* Use key array lookup instead of using hasOwnProperty.
* Avoid decoding known empty strings.
* Avoid possibly unnecessary switch to slower decoder for values if
key decoding throws.
stringify optimizations:
* Use manual loop for default encoder instead of encodeURIComponent.
* Use string concatenation instead of joining an array of strings.
* Avoid caching result of typeof.

Many of the util.is*() methods used to check data types
simply compare against a single value or the result of
typeof. This commit replaces calls to these methods with
equivalent checks. This commit does not touch calls to the
more complex methods (isRegExp(), isDate(), etc.).

Documentation states that `querystring.unescape` may be overridden to
replace unescaper during parsing. However, the function was only
being used as a fallback for when the native decoder throws (on a
malformed URL). This patch moves the call to the native function and
the try/catch around it into querystring.unescape then has the parser
always invoke it, so that an override will always be used.

QueryString.stringify() allowed a fourth argument that was used as a

If hasOwnProperty is overridden, then calling `obj.hasOwnProperty(prop)`
can fail. Any time a dictionary of user-generated items is built, we
cannot rely on hasOwnProperty being safe, so must call it from the
Object.prototype explicitly.
- Handle only the most basic of query string parsing and construction.
Leave the rest (e.g. Rails/PHP behaviors) to modules higher up the
stack, like Express.
