#20 Add an defined error ID (by number or tag) in exceptions.

[E.]

It would be very useful to add a ID-number in
exceptions when throwing them.

Something like :

#ifndef __EASYSOAP_ERROR_H__
#define __EASYSOAP_ERROR_H__

#define EASYSOAP_ERROR_UNREACHABLE -1
#define EASYSOAP_ERROR_SSLHANDSHAKEFAILURE -2
...
#endif

Usable when throwing exceptions :

throw SOAPException(EASYSOAP_ERROR_UNREACHABLE,"SOAP
Error : soap server unreachable");

or

throw SOAPException(EASYSOAP_ERROR_UNREACHABLE);

_ it will be easyer to identify errors.
_ it will help to use langage-based messages.

Right now (and if I didn't missed anything) it's very
hard to handle errors except saying "it failed".

I've made a patch to the CVS 2003-04-15 version to add that
feature.

_ The exceptions have a new int m_code member.
_ The exceptions have a new int Code() method.
_ The exceptions have two new constructors, basically the
same as the old ones, but starting with an "(int code,"
parameter.
_ A new file "SOAPExceptionsTag.h" holds the defines of the
exceptions codes as well as a few comments.

Expected problems :

_ Some codes could be redundant (the general exceptions moslty).

_ Some codes could be irrelevant for a library application
using EasySoap

I've not used yet the windows implementation code, but it's
modified (I'm using both Linux & Windows) and I guess it
should work.

I'm moslty using the socket/ssl exceptions codes.

unified patch attached, to be applied on the 2003-04-15 CVS
tree.
