Cannot add extra data with the same name as existing extra data

[Ian Culverwell]

If you try to, you hit a netCDF error:

FATAL ERROR (from ropp_io_write_ncdf_def):  NetCDF: String match to name in use

The simplest solution is to check that the name isn't already in use, and issue an ERROR message if it is, in which case the newly computed extra data will not be appended to the ROprof structure. This has been done at r4927. If you try to add extra data with a matching name to existing extra data, ROPP now says, for example,

ERROR (from ropp_io_addvar_rodataD2d):  The name "gradient_bangle" is already in use ... cannot add the newly computed variable to the ROprof structure.
... (from ropp_io_addvar_rodataD2d):  (Try removing it from the input file from which it was probably read.)

As a result of this change, ropp_fm_bg2ro_1d.f90 has been updated at r4928.

This tests out OK, so closing ticket.
