Change variables that have intrinsic function and keyword argument names to different descriptive names

[mcallic2]

Is your feature request related to a problem? Please describe.
As the modern fortran language has expanded and been improved upon, there are many variables within the FMS codebase that have the same names as these keywords or functions.

For example, data is used in many instances throughout the code as a variable name whether it be a dummy argument or module level variable. data has been defined as a keyword for the release of Fortran 77. The functionality of the data keyword is such that it initializes variables, substrings, arrays, and array elements.

This is just one of many examples of these keywords/functions that are now defined in newer versions (Fortran 77 and above). Some others that have been found in FMS are: name, unit, etc.

Describe the solution you'd like
I propose to change these variable names that have other functionality to different, more descriptive variable names
