This provides finer control as to when the changes get constructed and
initial stitching is performed. These is needed by certain processes,
notably decomposition and reconstruction.
By default, the mesh still performs all these operations on a "normal"
read-construction. A flag has to be passed explicitly to the constructor
in order to prevent the post-construction steps.
The timeName() function simply returns the dimensionedScalar::name() which holds
the user-time name of the current time and now that timeName() is no longer
virtual the dimensionedScalar::name() can be called directly. The timeName()
function implementation is maintained for backward-compatibility.
Replaced all uses of complex Xfer class with C++11 "move" constructors and
assignment operators. Removed the now redundant Xfer class.
This substantial changes improves consistency between OpenFOAM and the C++11 STL
containers and algorithms, reduces memory allocation and copy overhead when
returning containers from functions and simplifies maintenance of the core
libraries significantly.
