Reconstruct 9 and 13 support for HISQ longlinks
Fixed bug in half-precision FloatNOrder::save.
Added preprocessor directives, so that the recon 9/13 options in
copy_gauge.cu are only built if staggered fermions are being used.
Fixed compilation errors and warning on pre-Kepler architectures, introduced in commit cdc5907f90066258322613197bc7230b1213adc1.
Solvers now explicitly check for Nan in the residual.
Cleanup up verbosity and tuning settings: now always use getVerbosity() and getTuning() helpers, removed all other verbosity members.
Fixed logic so that CG has no tolerance for residual increases between consequtive reliable updates
Renabled tuning of twistGamma5 kernel and set the tuneKey to distinguish on twist flavor.
Use std::isnan to resolve ambiguity.
Solvers now use global verbosity state.
Fixed uninitialised variable warnings to silence valgrind.
Moved qdp_quda.h header inclusion to malloc.cpp to avoid any potential pollution.  Additionally quda::Complex now defined in quda_internal.h, not color_spinor_field.h.
Replaced real() and imag() occurances with REAL() and IMAG() macros to work around C++98/C++11 ABI incompatibilities.
Fixed bug in IMAG macro definition.
Remove c++0x flag when building with QDP-JIT support
Fixed error when compiled with c++11
Fixed staggered RHMC components not updated for getVerbosity() and getTuning()

Updated the declaration of computeFatLinkCore.

computeFatLinkCore is used in the MILC interface. This is probably the
worst design you could imagine, but it works and will do for the time being.
Added fix for gcc-4.7 compilation.
