* Torrent Instantiation
*
* Instantiating a tr_torrent has gotten a lot more complaticated as we
* add more options to them. At the worst point there were four functions
* to check metainfo, and four (or five) functions to create tr_torrents.
* They all did mostly the same thing, but each was just *slightly* different.
*
* To remedy this, a Torrent Constructor (struct tr_ctor) has been introduced:
* + Simplifies the API down to two (non-deprecated) functions.
* + You can set the fields you want; the system sets defaults for the rest.
* + You can specify whether or not your fields should supercede fastresume's.
* + We can add new features to tr_ctor without breaking tr_torrentNew()'s API.
*
* All the tr_ctor{Get,Set}*() functions with a return value return
* an error number, or zero if no error occurred.
*
* You must call one of the SetMetainfo() functions before creating
* a torrent with a tr_ctor. The other functions are optional.
*
* You can reuse a single tr_ctor to create a batch of torrents --
* just call one of the SetMetainfo() functions between each
* tr_torrentNew() call.
*
* Every call to tr_ctorSetMetainfo*() frees the previous metainfo.
