DA utility bug fixes

[RussTreadon-NOAA]

Cycled global parallel tests on Orion identified two small bugs in the authoritative NOAA-EMC/GSI develop.

1. util/EnKF/gfs/src/getsigensmeanp_smooth.fd/getsigensmeanp_smooth_ncep.f90
   When intrinsic nargs() replaced with iargc(), we should have changed the threshold against which we test. nargs() returns the total number of command line arguments, including the command. iargc() returns the index of the last command line argument. The line 105 logical test with iargc() should now check for > 4, not > 5. As currently coded the iargq() > 5 test is .false. when the fifth argument for ensemble spread is included on the command line. Changing the logical test to iargc() > 4 restores the intended behavior.

2. util/netcdf_io/calc_analysis.fd/CMakeLists.txt
   The target_link_libraries section of CMakeListx.txt references w3emc_d. The w3movdat call in init_io.f90 uses a real(4) array. The w3emc_d w3movdat incorrectly processes the input and returns an incorrect date. Linking w3emc_4 results in the correct behavior from w3movdat.

This issue is opened to document these bugs and their fixes.
