William S Fulton 26b0911a74 Add support for $n special variable expansion in the names of typemap local variables 
For example:

  %typemap(in) int MYINT (int $1_temp) { ... }

$1_temp is typically expanded to arg1_temp, arg2_temp etc depending on
which argument the typemap is applied to.

William S Fulton e8d3c74590 Improvements to $typemap() special variable replacement overrides 
In $typemap(), the $n special variables are replaced by the appropriate
value for the type associated with the typemap calling $typemap().
The (undocumented) special variable overrides now also support
controlling what the $n special variables are replaced with from the
calling typemap, for example:

  %typemap(in) std::pair<std::string, int> {
    int& input_value_second = $1.second;
    $typemap(in, int, 1=input_value_second);
    ...
  }

replaces $1 in the int typemap with input_value_second instead of
whatever is the default for the target language (a variable that holds
the int value after marshalling from the target language).

This additional functionality might make it possible to replace the C++
templates used in the UTL with a much simpler system of typemaps utilising
$typemap(). See follow on commit to typemaps.c.
