QDict: Introduce new iteration API
It's composed of functions qdict_first() and qdict_next(), plus functions to access QDictEntry values. This API was suggested by Markus Armbruster <armbru@redhat.com> and it offers full control over the iteration process. The usage is simple, the following example prints all keys in 'qdict' (it's hopefully better than any English description): QDict *qdict; const QDictEntry *ent; [...] for (ent = qdict_first(qdict); ent; ent = qdict_next(qdict, ent)) { printf("%s ", qdict_entry_key(ent)); } Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
