Add support for parallel extraction of component archives
Introduce ConcurrentOperationRunner class used for running
installer operations concurrently in the global thread pool.
Add execution groups for operations; Unpack operations are run
concurrently for all components requesting installation,
operations belonging to Install group are run sequentially for
sorted components one at a time as before. From the default
registered operations the Extract op is moved to Unpack group.
Move the previously on-the-fly backup steps of Extract operation
to the ExtractArchiveOperation::backup(), so that backups are
done before any archives are extracted, and that we know if any
of the archives requires administrator privileges to unpack.
Reparent QInstaller::Error to QException to support throwing
and catching exceptions across thread boundaries.
Use RAII for the server-side objects of the classes supporting
the remote client-server protocol of installer framework. The
concurrent extraction revealed that it was still possible that
the local socket was disconnected and thus the RemoteServer-
Connection thread finished before receiving and processing the
final "Destroy" command packet, leaking the dynamically
allocated objects.
