Latin1 strings are usually stored as 8 bit data in the json binary
format. But that data structure has a size limitation of 16bit, so
we need to fall back to storing the string as 16 bit data if it is
too long.

In JSON, any number is stored in double. We need to make sure we
keep the maximum possible number precision for integer number. In
IEEE 754 double format, the significand precision is 53 bits(52
explicityly stored).
Autotest is included. qint64 and double work fine.

Previously only 32bit signed integers were ensured to be supported by
JsonValue type via API but it is expected that a larger integer range
should be supported by a JSON implementation.
This commit brings the Qt implementation into parity with NodeJS
JSON.stringify() in respect of the JavaScript Number type.

Previously Qt JSON writer would only emit 6 digits of precision as this
is the default with the formatter.
However with testing against NodeJS JSON.stringify() this behavior is
inconsistent with the defacto standard JSON implementation and conveys
a loss of precision.

My interpretation of RFC4627, Section 2.4 "Numbers" of:
Numeric values that cannot be represented as sequences of digits
(such as Infinity and NaN) are not permitted.
I have also verified this matter with NodeJS JSON.stringify() that
emitting a null is consistent behavior with a JSON implementation
written in JavaScript.
Previously Qt would emit:
{
plusInfinity: inf,
minusInfinity: -inf,
notANumber: nan
}
Which maybe turned into a string values of "inf", "-inf", "nan" by
the receiving parser. Now it returns the JSON null value just like
NodeJS JSON.stringify().

The writer delegate used by QJsonDocument to produce a Json QByteArray
supports generating a human readable Json (with spaces and carriage
returns that reflect the Json structure) and a less human readable (no
spaces nor carriage returns) but more compact Json.
The method toJson() was extended with a format argument to support
the compact Json generation.

The parser is recursive and too deeply nested json would
cause it to exhaust the available stack space leading to

We now abort parsing with a DeepNesting parse error if the
document is too deeply nested. The current nesting limit
is set to 1024, which should be more then enough for any
real JSON data set.
