Introduce a transaction mechanism that gives the ability to read the
data atomically. Current implementation supports transactions for both
types of devices. For sequential devices, it records the whole input
stream during transaction. For random-access devices, device position
is saved when transaction starts. If an error occurs, the application
may be able to recover the input stream by rolling back to the start
point.

Also, QIODevice::peek() was rewritten to make use of transactions
internally. The replacement of QIODevicePrivateLinearBuffer by
QRingBuffer is closely entangled with that, which makes it unfeasible
to do separately.

This fixes the problem as long as we have C++ 11's semantics for
in-function statics.  The Q_GLOBAL_STATIC_WITH_ARGS() is a non-trivial
wrapper whose destructor gets unloaded with the plugin, leading to a
crash-on-exit if the global it wraps outlives the plugin.  The plain
(in-function) static manages to avoid this by avoiding the wrapper.
As the static was only needed in one place, this proves a sufficient
solution to the plugin-unload problem *in this case*.

For almost the whole of its life time, 'realname' has the same
prefix, but the old code used the same string-builder expression
to construct it over and over again. If QStringBuilder would
re-use the capacity of the LHS object, that would boil down to
just a bit more copying of characters than necessary. But
assigning a QStringBuilder expression to a QString works by
implicit conversion of the QStringBuilder expression to a
QString, followed by move-assigning the new QString into the
old.

The new code keeps the common prefix around, resetting
'realname' to that prefix with truncate, only appending the
varying suffixes. In this way, one memory allocation per
assignment is saved (ignoring a potentially required capacity
increase in one of the appends here), and also some out-of-line
QString dtor calls, since op+=(QString&, QStringBuilder...)
doesn't create a temporary QString.

Also saves ~1KiB in text size on optimized GCC 4.9 Linux AMD64
builds.
