virsh: Switch from generated cmd*Edit commands to nongenerated 

Currently, we either generate some cmd*Edit commands (cmdPoolEdit
and cmdNetworkEdit) via sed script or copy the body of cmdEdit
(e.g. cmdInterfaceEdit, cmdNWFilterEdit, etc.). This fact makes
it harder to implement any new feature to our editing system.
Therefore switch to new implementation - define macros to:
- dump XML (EDIT_GET_XML)
- take an action if XML wasn't changed,
  usually just vshPrint() (EDIT_NOT_CHANGED)
- define new object (EDIT_DEFINE) - the edited XML is in @doc_edited
- free object defined by EDIT_DEFINE (EDIT_FREE)
and #include "virsh-edit.c"

/*
* virsh-edit.c: Implementation of generic virsh *-edit intelligence
*
* Copyright (C) 2012 Red Hat, Inc.
*
* See COPYING.LIB for the License of this software.
*
* Usage:
* Define macros:
* EDIT_GET_XML - expression which produces a pointer to XML string, e.g:
* #define EDIT_GET_XML virDomainGetXMLDesc(dom, flags)
*
* EDIT_NOT_CHANGED - this action is taken if the XML wasn't changed.
* Note, that you don't want to jump to cleanup but edit_cleanup label
* where temporary variables are free()-d and temporary file is deleted:
* #define EDIT_NOT_CHANGED vshPrint(ctl, _("Domain %s XML not changed"), \
* virDomainGetName(dom)); \
* ret = true; goto edit_cleanup;
* Note that this is a statement.
*
* EDIT_DEFINE - expression which redefines the object. The edited XML from
* user is in 'doc_edited' variable. Don't overwrite the pointer to the
* object, as we may iterate once more over and therefore the pointer
* would be invalid. Hence assign object to a different variable.
* Moreover, this needs to be an expression where:
* - 0 is taken as error (our virDefine* APIs often return NULL on error)
* - everything else is taken as success
* For example:
* #define EDIT_DEFINE (dom_edited = virDomainDefineXML(ctl->conn, doc_edited))
*
* EDIT_FREE - statement which vir*Free()-s object defined by EDIT_DEFINE, e.g:
* #define EDIT_FREE if (dom_edited) virDomainFree(dom_edited);
*
