Note that this patch does not introduce any real temperature
dependence but only changes the APIs for the viscosity and for the
density related methods. Note that I also don't like the fact that
this requires so many changes to so many files, but with the current
design of the property classes I cannot see a way to avoid this...
the largest change is that all classes below opm/core/props/pvt take
the PVT region index as an argument, the higher-level ones (i.e.,
BlackoilProps*) take cell indices.
The pvt interface is extended to handle wet-gas systems:
1. rvSat is added as a function in the PVT interface
2. SinglePvtLiveGas computes the pvt values and its derivatives
3. The old rbub variable is changed to rsSat for clearity
4. The new interface is tested in test_blackoilfluid with data from
liveoil.DATA and wetgas.DATA
Commit a5a4d7b introduced density and viscosity evaluators into the
SinglePvtInterface that accepted an externally assignable condition
to distinguish saturated from unsaturated cases. As a result of a
few low-level technical problems with that approach, this commit
changes those affected interfaces to use the black-oil specific
'PhasePresence' facility of commit a033329 instead.
Update tests and callers accordingly.

Functions for volume factor and viscosity that explicitly take a boolean
variable indicating whether the fluid is saturated or not is added to
the SinglePvtInterface.
Corresponding changes are done in the dependent PVT files.
The new functionality is tested in test_blackoilfluid
our policy is that we only use boost if necessary, i.e., if the oldest
supported compiler does not support a given feature but boost
does. since we recently switched to GCC 4.4 or newer, std::shared_ptr
is available unconditionally.
Variably-sized arrays of the form
int n = 6;
double a[n];
are an extension to the language that will illicit a suitably
persnickety diagnostic from GCC when invoked with "-pedantic".
