make it act properly on iobuf errors.

btpd can handle for now, so if no such URLs exists there will be a
lot of tracker errors reported.

with active net.

The add and del commands adds or removes torrents from this library.
The start and stop commands are used to active or deactivate torrents.
Also, a mechanism for qeurying data on torrents has been added. It's
only used by the btcli list and stat commands yet though.

btcli has been split into different files for each command.

Both btpd and btcli now use misc/btpd_if.h for all ipc definitions.

Misc changes:
- struct metainfo is gone. Use the new mi_* functions.
- Add printf format type checking where appropriate.

Use the fact that we only can store structs in the table to make the
complex pointer use safe. Unfortunately the equal and hash functions
need to take void * arguments.

interface.

add   - adds a torrent to btpd's library
del   - removes a torrent from btpd's library
start - activates a torrent from the library
stop  - deactivates an active torrent
tget  - get data from torrents

tget obsoletes stat and list.

Commands for setting values and query other data will be
added later.

The metainfo struct has been replaced by functions for qeurying specific
items from the torrent. In addition, the tests of the torrent data has
been improved.

Add function for reading a whole file.
Enable printf format checking for some functions.

Strangely such connections are not entirely uncommon. Added a hand shake
time out of 60 seconds to resolve this.

Added a peer_on_tick function which is used to monitor peers for different
timeouts. Timestamps are compared against the reborn btpd_seconds.

The issue has been reported by Ludvig Omholt and Arnaud Bergeron.

the percentage upwards. Ie. Display 99.9%, not 100.0%, even if we have
99.98% of the content.

cleared for a failed piece in the full torrent test. This also fixes a bug
where the content byte count wasn't decreased for failed pieces.

failed for pieces in modified files. Oops!
