iv_xlateVc and iv_xlateLvc not exported

[m1h43l]

The two mentioned functions are not exported by the service program (also not in the binder source). There is also no matching function in the xlate module. The exported functions of the `xlate module are:

• xlate_translateString
• xlate_translateLongVarchar
• xlate_translateVarchar
• xlate_translateDescriptor
• xlate_translateBuffer
• xlate_open

My guess is that these functions are propably:

• iv_xlateVc -> xlate_translateVarchar
• iv_xlateLvc -> xlate_translateLongVarchar

But the prototype signatures doesn't match.

@NielsLiisberg So are we making some wrapper functions in the api module so that it fits into the iv namespace? Exporting the function with the xlate namespace might get us into a conflict when you export those helper functions also from another project. I would like to only export functions in the ilevator service program with the iv namespace.
