Non-const access to the internal field now obtained from a specifically
named access function consistent with the new names for non-canst access
to the boundary field boundaryFieldRef() and dimensioned internal field
dimensionedInternalFieldRef().

There is a need to specify const or non-const access to a non-const
object which is not currently possible with the "boundaryField()" access
function the const-ness of the return of which is defined by the
const-ness of the object for which it is called. For consistency with
the latest "tmp" storage class in which non-const access is obtained
with the "ref()" function it is proposed to replace the non-const form
of "boundaryField()" with "boundaryFieldRef()".
Thanks to Mattijs Janssens for starting the process of migration to
"boundaryFieldRef()" and providing a patch for the OpenFOAM and
finiteVolume libraries.
Foam::direction is an unsigned type which makes it easier for the
compiler to pickup and report errors in the instantiation of
VectorSpaces and associated types.
in case of tmp misuse.
Simplified tmp reuse pattern in field algebra to use tmp copy and
assignment rather than the complex delayed call to 'ptr()'.
Removed support for unused non-const 'REF' storage of non-tmp objects due to C++
limitation in constructor overloading: if both tmp(T&) and tmp(const T&)
constructors are provided resolution is ambiguous.
The turbulence libraries have been upgraded and '-DCONST_TMP' option
specified in the 'options' file to switch to the new 'tmp' behavior.
This resolves a whole range of issues and work-arounds with earlier
releases. This version of icpc is more or less compatible with the
latest gcc and clang compilers and only required one hack to avoid
warnings from PackedBoolList.H.
