By default, the read chunk size is QIODEVICE_BUFFERSIZE and the write
chunk size is 0 (which means that we don't use the internal write buffer).
Derived classes may override these values to define the size of
QIODevice's write buffer or to optimize the read buffer use.

Some sequential devices allow data to be partitioned into several
channels that have the property of independently sequenced delivery.
Supporting such devices uniformly requires a unified API which provides
the user with a uniform concept of multistreaming.
This patch is based on QProcess's multiplexing model and introduces
the following features:
- ability to get the number of channels;
- multiple internal read/write buffers;
- channel selection functions;
- notification signals on channel activity.
To keep the source code compatible with single-channel implementations,
introduce a private class that references the current read buffer and
hides multistreaming internals from the user.

This fixes the rendering of translucent borders on CSS-styled widgets to
prevent visible overlapping at the corners. This is done by using a
miter joint (45 degree angle) if either of the adjacent edges are
translucent. Previously, adjacent edges would be drawn at full length
and overlap at the corners if both edges are BorderStyle_Solid and have
identical QBrush objects. This works if both QBrush objects are opaque
but causes visible overlap if one or both of them are translucent.

The old code searched for any Qt containers by looking at
- each class definition
- each property's type
- each function (signal, slot, method)
- each argument type
and matching each against "Container<", building
the pattern string each time through the loop.
It would then collect hits in a QSet to be converted
to a QList and sorted at the very end.
The new code pulls the iteration over the candidates
out of all other loops. By doing so, it can stop
looking at classes, properties, functions etc when
it finds the first hit, and it inserts every candidate
at most once.
By iterating over the statically-known list of
candidates, the result is not a sorted set of Qt
containers, as before, but it still has s fixed order
across runs, which was the purpose of the sorting in
the original code.
In the implementation, make liberal use of C++11
range-for, which is safe, as we're passing everything
around as const.

Whenever there are spies installed, we call out to the main thread to
call to the kded/kiod message spies. This allows the spy code to do just
about anything, where previously it was restricted in what it could do
to avoid deadlocking or triggering assertions if it recursed back into
QDBusConnection code in the manager thread. After the spies are done,
the message is re-inserted into the QDBusConnection processing pipeline.
This commit moves the spy handling to after the check for disabled
dispatching, as doing otherwise would mean the message could get
postponed again for no good reason. It's also possible that the main
thread isn't done installing the hooks, so waiting until the dispatching
is enabled is a good idea.
For simplicity, this commit also restricts spying to method calls
only. Signals are no longer spyable.
