Create corelib/serialization and move existing file formats into it

This is in preparation to adding CBOR support. We don't need yet another
dir for CBOR and placing it in src/corelib/json is just wrong.

-  \class QXmlStreamReader
-  \inmodule QtCore
-  \reentrant
-  \since 4.3
-
-  \brief The QXmlStreamReader class provides a fast parser for reading
-  well-formed XML via a simple streaming API.
-
-
-  \ingroup xml-tools
-
-  QXmlStreamReader is a faster and more convenient replacement for
-  Qt's own SAX parser (see QXmlSimpleReader). In some cases it might
-  also be a faster and more convenient alternative for use in
-  applications that would otherwise use a DOM tree (see QDomDocument).
-  QXmlStreamReader reads data either from a QIODevice (see
-  setDevice()), or from a raw QByteArray (see addData()).
-
-  Qt provides QXmlStreamWriter for writing XML.
-
-  The basic concept of a stream reader is to report an XML document as
-  a stream of tokens, similar to SAX. The main difference between
-  QXmlStreamReader and SAX is \e how these XML tokens are reported.
-  With SAX, the application must provide handlers (callback functions)
-  that receive so-called XML \e events from the parser at the parser's
-  convenience.  With QXmlStreamReader, the application code itself
-  drives the loop and pulls \e tokens from the reader, one after
-  another, as it needs them. This is done by calling readNext(), where
-  the reader reads from the input stream until it completes the next
-  token, at which point it returns the tokenType(). A set of
-  convenient functions including isStartElement() and text() can then
-  be used to examine the token to obtain information about what has
-  been read. The big advantage of this \e pulling approach is the
-  possibility to build recursive descent parsers with it, meaning you
-  can split your XML parsing code easily into different methods or
-  classes. This makes it easy to keep track of the application's own
-  state when parsing XML.
-
-  A typical loop with QXmlStreamReader looks like this:
-
-  \snippet code/src_corelib_xml_qxmlstream.cpp 0
-
-
-  QXmlStreamReader is a well-formed XML 1.0 parser that does \e not
-  include external parsed entities. As long as no error occurs, the
-  application code can thus be assured that the data provided by the
-  stream reader satisfies the W3C's criteria for well-formed XML. For
-  example, you can be certain that all tags are indeed nested and
-  closed properly, that references to internal entities have been
-  replaced with the correct replacement text, and that attributes have
-  been normalized or added according to the internal subset of the
-  DTD.
-
-  If an error occurs while parsing, atEnd() and hasError() return
-  true, and error() returns the error that occurred. The functions
-  errorString(), lineNumber(), columnNumber(), and characterOffset()
-  are for constructing an appropriate error or warning message. To
-  simplify application code, QXmlStreamReader contains a raiseError()
-  mechanism that lets you raise custom errors that trigger the same
-  error handling described.
-
-  The \l{QXmlStream Bookmarks Example} illustrates how to use the
-  recursive descent technique to read an XML bookmark file (XBEL) with
-  a stream reader.
-
-  \section1 Namespaces
-
-  QXmlStream understands and resolves XML namespaces. E.g. in case of
-  a StartElement, namespaceUri() returns the namespace the element is
-  in, and name() returns the element's \e local name. The combination
-  of namespaceUri and name uniquely identifies an element. If a
-  namespace prefix was not declared in the XML entities parsed by the
-  reader, the namespaceUri is empty.
-
-  If you parse XML data that does not utilize namespaces according to
-  the XML specification or doesn't use namespaces at all, you can use
-  the element's qualifiedName() instead. A qualified name is the
-  element's prefix() followed by colon followed by the element's local
-  name() - exactly like the element appears in the raw XML data. Since
-  the mapping namespaceUri to prefix is neither unique nor universal,
-  qualifiedName() should be avoided for namespace-compliant XML data.
-
-  In order to parse standalone documents that do use undeclared
-  namespace prefixes, you can turn off namespace processing completely
-  with the \l namespaceProcessing property.
-
-  \section1 Incremental Parsing
-
-  QXmlStreamReader is an incremental parser. It can handle the case
-  where the document can't be parsed all at once because it arrives in
-  chunks (e.g. from multiple files, or over a network connection).
-  When the reader runs out of data before the complete document has
-  been parsed, it reports a PrematureEndOfDocumentError. When more
-  data arrives, either because of a call to addData() or because more
-  data is available through the network device(), the reader recovers
-  from the PrematureEndOfDocumentError error and continues parsing the
-  new data with the next call to readNext().
-
-  For example, if your application reads data from the network using a
-  \l{QNetworkAccessManager} {network access manager}, you would issue
-  a \l{QNetworkRequest} {network request} to the manager and receive a
-  \l{QNetworkReply} {network reply} in return. Since a QNetworkReply
-  is a QIODevice, you connect its \l{QIODevice::readyRead()}
-  {readyRead()} signal to a custom slot, e.g. \c{slotReadyRead()} in
-  the code snippet shown in the discussion for QNetworkAccessManager.
-  In this slot, you read all available data with
-  \l{QIODevice::readAll()} {readAll()} and pass it to the XML
-  stream reader using addData(). Then you call your custom parsing
-  function that reads the XML events from the reader.
-
-  \section1 Performance and Memory Consumption
-
-  QXmlStreamReader is memory-conservative by design, since it doesn't
-  store the entire XML document tree in memory, but only the current
-  token at the time it is reported. In addition, QXmlStreamReader
-  avoids the many small string allocations that it normally takes to
-  map an XML document to a convenient and Qt-ish API. It does this by
-  reporting all string data as QStringRef rather than real QString
-  objects. QStringRef is a thin wrapper around QString substrings that
-  provides a subset of the QString API without the memory allocation
-  and reference-counting overhead. Calling
-  \l{QStringRef::toString()}{toString()} on any of those objects
-  returns an equivalent real QString object.

-  \class QXmlStreamWriter
-  \inmodule QtCore
-  \since 4.3
-  \reentrant
-
-  \brief The QXmlStreamWriter class provides an XML writer with a
-  simple streaming API.
-
-  \ingroup xml-tools
-
-  QXmlStreamWriter is the counterpart to QXmlStreamReader for writing
-  XML. Like its related class, it operates on a QIODevice specified
-  with setDevice(). The API is simple and straightforward: for every
-  XML token or event you want to write, the writer provides a
-  specialized function.
-
-  You start a document with writeStartDocument() and end it with
-  writeEndDocument(). This will implicitly close all remaining open
-  tags.
-
-  Element tags are opened with writeStartElement() followed by
-  writeAttribute() or writeAttributes(), element content, and then
-  writeEndElement(). A shorter form writeEmptyElement() can be used
-  to write empty elements, followed by writeAttributes().
-
-  Element content consists of either characters, entity references or
-  nested elements. It is written with writeCharacters(), which also
-  takes care of escaping all forbidden characters and character
-  sequences, writeEntityReference(), or subsequent calls to
-  writeStartElement(). A convenience method writeTextElement() can be
-  used for writing terminal elements that contain nothing but text.
-
-  The following abridged code snippet shows the basic use of the class
-  to write formatted XML with indentation:
-
-  \snippet qxmlstreamwriter/main.cpp start stream
-  \dots
-  \snippet qxmlstreamwriter/main.cpp write element
-  \dots
-  \snippet qxmlstreamwriter/main.cpp finish stream
-
-  QXmlStreamWriter takes care of prefixing namespaces, all you have to
-  do is specify the \c namespaceUri when writing elements or
-  attributes. If you must conform to certain prefixes, you can force
-  the writer to use them by declaring the namespaces manually with
-  either writeNamespace() or writeDefaultNamespace(). Alternatively,
-  you can bypass the stream writer's namespace support and use
-  overloaded methods that take a qualified name instead. The namespace
-  \e http://www.w3.org/XML/1998/namespace is implicit and mapped to the
-  prefix \e xml.
-
-  The stream writer can automatically format the generated XML data by
-  adding line-breaks and indentation to empty sections between
-  elements, making the XML data more readable for humans and easier to
-  work with for most source code management systems. The feature can
-  be turned on with the \l autoFormatting property, and customized
-  with the \l autoFormattingIndent property.
-
-  Other functions are writeCDATA(), writeComment(),
-  writeProcessingInstruction(), and writeDTD(). Chaining of XML
-  streams is supported with writeCurrentToken().
-
-  By default, QXmlStreamWriter encodes XML in UTF-8. Different
-  encodings can be enforced using setCodec().
-
-  If an error occurs while writing to the underlying device, hasError()
-  starts returning true and subsequent writes are ignored.
-
-  The \l{QXmlStream Bookmarks Example} illustrates how to use a
-  stream writer to write an XML bookmark file (XBEL) that
-  was previously read in by a QXmlStreamReader.
