/* -----------------------------------------------------------------------
   Generic handling for "type **" parameters.  Almost all such parameters
   are OUTPUT parameters.  Handling is as follows:
   - "in" typemap which allocates storage for a pointer, and points the
     argument to that storage.
   - Default "argout" typemap which complains at compile time, and raises
     an exception at runtime.
   - OUTPARAM "argout" typemap which wraps (SWIG_NewPointerObj) a C
     pointer for return to the scripting language.
   - Application of the OUTPARAM typemap to those types for which it makes
     sense (key examples for which it does not are strings, arrays, and
     hashes - which need to be turned into their scripting language
     equivalent).
   Known instances of "type **" which are *not* OUTPUT parameters are:
   - svn_stream_checksummed(..., const unsigned char **read_digest,
                                 const unsigned char **write_digest, ...)
   - svn_*_change_rev_prop2(..., const svn_string_t *const *old_value_p, ...)

/* -----------------------------------------------------------------------
   MD5 Digest Parameters: in the Subversion C API, there are:
   - 'char' digests, which are hexadecimal-encoded strings.
   - 'unsigned char' digests, which are raw blocks of bytes.
   This section of typemaps relates to the second variety.
   The number of subtly different forms in which these appear in our
   APIs is absolutely scary, and we desperately must introduce some sanity
   when we do Subversion 2.0.

   Function Parameters (Category 1):

   'unsigned char digest[]'
   'unsigned char *digest':

     Output parameter in: svn_fs_file_md5_checksum(), svn_io_file_checksum(),
                          svn_wc_transmit_text_deltas2()

     *but* appears as an input parameter in svn_base64_from_md5() -
     practically, this means that svn_base64_from_md5 is in error, and
     should be using 'const unsigned char digest[]', but fortunately, we
     do not wrap the svn_base64_* APIs, so do not have to care here.


   (Category 2):

   There is no category 2!


   Function Parameters (No typemaps):

   'const unsigned char **read_digest' (also, 'write_digest'):
     These are *delayed* output parameters in svn_stream_checksummed().
     Would be quite complex to wrap, so this function is %ignore-d in the
     svn_io.h cherrypicking section.

   'unsigned char *result_digest'
     This parameter serves as a buffer for the digest results of
     svn_txdelta_apply. As you supply data to this function via
     the handler callback, this digest gets filled. Since
     filling of this buffer is delayed, it is quite difficult
     to wrap.

    FIXME: Both Ruby and Perl have broken typemaps for result_digest.
    The Python bindings ignore this parameter altogether.

   Function Parameters (Category 3):

   'const unsigned char digest[]' (also, 'd1', 'd2'):
   'const unsigned char *digest':
     Input parameters in:
     svn_md5_digest_to_cstring_display()
     svn_md5_digest_to_cstring()
     svn_md5_digests_match()

   Function return values (Category 4):

   'const unsigned char *' in svn_txdelta_md5_digest()
