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.

reply.

than curl.

to be standard.

in 0.12.

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.

library support some day...

write performance.

make_abs_path doesn't need the directories to actually exist in the
file system.

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.

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.

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

amount we have in the info file.

'btcli stop -a'.

improved error output.

not need to know about the sample time.
