TSMimeHdrFieldValueStringSet() sets the value of a MIME field. The field is identified by the combination
       of  bufp,  hdr,  and  field  which  should match those passed to the function that returned field such as
       TSMimeHdrFieldFind(). The value is copied to the header represented by bufp. value does not  have  to  be
       null terminated (and in general should not be).

       If idx is non-negative the existing value in the field is treated as a multi-value and idx as the 0 based
       index  of  which  element  to  set.  For  example  if  the  field  had the value dave,grigor,tamara and
       TSMimeHdrFieldValueStringSet() was called with value of syeda and idx of 1, the value  would  be  set  to
       dave,syeda,tamara.  If idx is non-negative it must be the index of an existing element or exactly one
       past the last element or the call will fail. In the example case idx must be between 0 and  3  inclusive.
       TSMimeHdrFieldValuesCount() can be used to get the current number of elements.

       This function returns TS_SUCCESS if the value was set, TS_ERROR if not.
