[PATCH] Implement prompt callback support for perl bindings

From: Ben Reser <ben_at_reser.org>
Date: 2003-11-27 11:13:32 CET

* subversion/bindings/swig/swigutil_pl.c
* subversion/bindings/swig/swigutil_pl.h
* subversion/bindings/swig/svn_client.i
* subversion/bindings/swig/perl/Core.pm
    Implement support in the perl bindings for the prompt functions
    (svn_client_get_simple_prompt_provider,
     svn_client_get_username_prompt_provider,
     svn_client_get_ssl_server_trust_prompt_provider,
     svn_client_get_ssl_client_cert_prompt_provider,
     svn_client_get_ssl_client_cert_pw_prompt_provider)
