* tc_setup_export_profile:

* In more detail, this function handles '--export_prof PROFILE'

* Also removes used option by options array, so later processing
* of used option is easier.
*
* Parameters:
* argc: POINTER to integer representing the number of items in argv
* array.
* argv: POINTER to array of C-string representing option keys
* and values.
* Return value:
* -2: internal error
* -1: bad parameters (== NULL)
* 0: bad option value
* >0: succesfull, and return value is number of profile parsed.
* Side effects:
* if operation is succesfull AND if user provided (valid) --export_prof
* option, both option and it's argument are removed from argv vector,
* so *TWO* items of argv vector will be NULL-ified, and argc is
* decreased by two.
* This function also trasparently set some internal variables.
* Preconditions:
* argc != NULL
* argv != NULL
