* the new workstruct also introduces a well defined buffer and result passing path
* a new function scan_find_keywords is a wrapper around scan_urlencoded_query that maps keys in url to values passed in an array of ot_keywords structs
* this new function cleans up much of url parameter parsing work, where read_ptr and write_ptr have been introduced rather than the confusing char *c, *data variables
* I now use memcmp instead of byte_diff to allow compiler to optimize constant size string compares
* got rid of UTORRENT_1600_WORKAROUND
* livesync_ticker is now only called from one (currently main) thread to avoid race conditions
Clean all torrents now only cleans one bucket at a time
All torrents that are being worked upon in an announce are being cleaned on demoand
torrent's peer lists now keep extra counts for seeds and peers to speed up scrape and announce
Sync has gone for now. I will think up a new way to implement. The old one was way to slow.
* implemented basic blacklisting:
** the file specified with -b <BLACKLIST> is read and added to a blacklist vector
** if an announce hits a torrent in that blacklist vector, add_peer_to_torrent fails
** sending a SIGHUP to the program forces it to reread the blacklists
** the server returns with a 500, which is not exactly nice but does the job for now
** an adaequat "failure reason:" should be delivered... TODO
We do not copy input buffer to socket's input array anymore, if we find \n in first buffer
We simplified parsing of input string
We removed asserts that were needed to debug negative seeder counts
We split static input and output buffers for obvious reasons
We enlarged static output buffer to prepare multi scrape functionality
We removed -lm from Makefile, this lib was only needed, when our random algorithm worked on floats
We close fds now that come with an empty iocookie into write loop, those don't make sense
We documented query string parser in opentracker.c a lot better to help auditing
