This adds a 'rate' command to modify the up and download
rates on the fly.

Closes GH-10

It sorts by name instead of number (should probably add options for sorting).
It now also takes torrents to list as optional arguments. Added ratio to
btcli stat display. Changed the help text for both commands. Some code shuffle
and other tweaks.

improved error output.

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

1. Show the number of torrents with tracker errors on the total status line.
2. Show the torrent status character on the status line instead of the name
   line. This only has effect when the '-i' flag is given.

torrents.

has moved toward btpd having a library of torrent to wich one may add
or remove torrents, and where interaction on torrents are done by their
assigned number. This commit is a step back from that and it makes life
simpler and better for all :)

* Some options to btpd has changed:
  --no-daemon is the old -d.
  -d is now used to specify the btpd directory.
  --logfile option is reintroduced.
* The ipc code has been improved on both btpd and cli sides.
* All commands have been implemented.
* Various improvements in btpd.

With this commit we're very close to 0.8 :)

o Lot of work on the cli and its communication with btpd.

Tabs have been converted to spaces and trailing whitespace have been removed.
I have fixed my emacs settings now :P

Each piece must have at least one byte for their block bit array,
  or they will collide causing great confusion in btpd. The calculation
  was done wrong so this could happen for small torrents (blocks / piece < 8).

policy_subr.c:
  * Add test for correctness.
  * Add missing call to cm_on_piece_full in cm_new_piece.

instead of the ideal.
