o Some new source files.
o Inclusion of libevent.
o Removal of curl and pthreads dependencies.

buffers, we put placeholder buffers on the list and fill them as they are
needed. At most 4 blocks will be filled per peer we upload to. This number
should probably be made tunable or be based on SO_SNDBUF or something.
Anyway, this should lower btpd's memory usage if one has many uploads.

tracker reply.

for the number of tracker errors to tolerate when we're stopping.

for state changes when appropriate instead of being called directly at any
time.

thread messaging code. Also simplify some interfaces by polling for
state changes when appropriate instead of being called directly at any
time.

unless libevent uses the select method.

allows me to add code for other types of trackers.

Remove the curl interface glue, since I use my own http client now. The curl
code was my main reason for using threads, so I'm a large step closer to make
btpd unthreaded again.

to be standard.

the content code shuts down btpd on errors. When that is fixed this code can
be removed.

hierarchy to a specified torrent content directory if neccessary.

yet anyway. glibc doesn't have the d_namlen field in struct dirent, so
we'll have to use strlen instead.

stream abstraction skip past them.

for torrent size and amount gotten when the torrent isn't active.

amount we have in the info file.

'btcli stop -a'.

not need to know about the sample time.

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.

the piece. Remove seeder peers when our download is finished and remove peers
who doesn't show any interest for a long time when we're seeding.

started when btpd starts. The new '--empty-start' option turns this off.

a tracker with connections even if we add a lot of torrents with the same
tracker at the same time.

libevent backend didn't like the fd to be closed. Reported by Ludvig Omholt.

socket. From Arnaud Bergeron.

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.

directly. Failure to add or delete an event is treated as a fatal error.

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.

runs was quite broken. Pieces stayed marked as ok event though the hash test
failed for pieces in modified files. Oops!
