We are running out of type ids for built-in types, 255 is not enough.
QMetaType already contains about ~70 types, situation is maybe not
tragic now, but there is a great chance that we will want to add more
built-in types from different modules like jsondb or declarative. Then
it might be tight, because we are not allowed to reorganize type ids
(it would be a binary incompatible change).
This change was not possible up to now. Old moc generated code assumes
that type id can be safely stored in 8 bits.
This is source compatible change.

For Qt5 we no longer want to support the older revisions due to the
dual codepaths that must be maintained, and because the format of the
meta-object data is quite different in revision 7.
The dual codepaths have been replaced by asserts that indicate the
revision in which the feature was introduced, and the older-revision
fallbacks have been removed.
It's not possible to build code generated by moc that has
revision <= 6 with Qt5 because the type of the
QMetaObject::stringdata member changed from const char * to const
QByteArrayData *. For the same reason it's not possible to build a
dynamic meta-object generator targeting revision <= 6 with Qt5.
Hence, too old meta-objects will be caught at compile time, and the
code will have to be ported to generate revision 7 (e.g., by running
Qt5's moc on the original class declaration).

QMetaMethod::typeName() is documented to return an empty string if
the return type is void. But after the introduction of
QMetaType::UnknownType (where void was made a distinct type),
returning an empty string causes the idiom
QMetaType::type(method.typeName())
to break; the result will be QMetaType::UnknownType rather than
the expected QMetaType::Void for methods that return void.
New code should use the new function QMetaMethod::returnType()
instead, but it would be good if existing code still did the right
thing.
The consequence of returning "void" instead of an empty string is
that it breaks existing logic that uses the typeName() length to
determine whether a method returns void. But we judge this as the
lesser of the two evils; it's better to have a typeName() function
that is consistent and keeps the QMetaType::type(method.typeName())
idiom working, than to force the typeName() inconsistency for void
only to keep code that does "strlen(method.typeName()) == 0"
working.
The places in Qt that were relying on a zero-length typeName()
(testlib, dbus, declarative) have already been changed to use
returnType().
Also adapt QMetaObjectBuilder, which is internal API.

This commit introduces two significant changes to the meta-object
data format:
1) Meta-type information (QMetaType type/name) information is
stored directly in the meta-data for both properties and methods;
2) The original signature (string) of a method is no longer stored
in the meta-data, since it can be reconstructed from the method
name and parameter type info.
The motivation for this change is to enable direct access to method
names and type information (avoiding string-based lookup for types
if possible), since that's typically the information language
bindings (e.g. QML) need. (moc already had all the desired
information about methods, but it threw it away!)
This change keeps support for the older (6 and below) meta-object
revisions, but the support will be removed after a short grace
period.
The following public QMetaMethod functions have been added:
name() : QByteArray
returnType() : int
parameterCount() : int
parameterType(int index) : int
The following internal QMetaMethod function has been added:
getParameterTypes(int *types) : void
This commit extends the meta-method data to include explicit
type/name data for methods. The new data follows the existing
(5-word) method descriptors in the meta-data. The method descriptor
format was modified to enable this. First, the descriptor now
contains the meta-data index where the method's type/name information
can be found. Second, the descriptor contains the number of
parameters. Third, the descriptor has a reference to the name of the
method, not the full signature.
Each entry of a method's type/name array contains either the type id
(if it could be determined at meta-object definition time), or a
reference to the name of the type (so that the type id can be
resolved at runtime).
Lastly, instead of storing the method parameter names as a
comma-separated list that needs to be parsed at runtime (which was
how it was done prior to this commit), the names are now stored as
separate entries in the meta-object string table, and their indexes
are stored immediately after the method type info array. Hence,
parameter names can be queried through the public API without
parsing/allocating/copying, too.

Changing the return type to QByteArray can lead to silent bugs due to

Up to and including meta-object revision 6, string data have been
stored as 0-terminated C-style strings, that were made directly
accessible as const char pointers through the public API
(QMetaMethod and friends).
This commit changes moc to generate an array of QByteArrayData
instead, and adapts the QObject kernel accordingly.
Generating an array of QByteArrayData (byte array literals)
means that the strings can now be returned from public (or private)
API as QByteArrays, rather than const char *, with zero allocation or
copying. Also, the string length is now computed at compile time
(it's part of the QByteArrayData).
This commit only changes the internal representation, and does
not affect existing public API. The actual (C) string data that the
byte array literals reference still consists of zero-terminated
strings. The benefit of having the QByteArrayData array will only
become apparent in the upcoming meta-object data format change, which
changes the format of property and method descriptors.
Support for the old meta-object string data format was kept; the
codepaths for old revisions (6 and below) will be removed in a
separate commit, once all the other meta-object changes are done and
affected code has been adapted accordingly.
