rtorrent: updated to 0.10.0

RTorrent release version 0.10.0

Thanks to a 3rd party sponsoring development, and recent changes in my personal \ 
life, I've started actively developing rtorrent.

Some of the recent PR's merged include:

libtorrent

Significant performance improvements to improve throughput and reduce CPU usage.
A fix for a torrent client crash with the socket address object.
Support for 33 gigabit speed throttles on ruTorrent.

rTorrent

A fix for a torrent client stack overflow crash with the lockfile buffer.
New trackers.delay_scrape command for .rtorrent.rc to avoid crashes with \ 
thousands of torrents and allow instant startups.
A fix for compiling the software with LTO (Link Time Optimizations) for \ 
additional performance.
A fix for a critical memory leak with RPC commands which may waste an alarming \ 
amount of memory.
A fix for critical torrent client breakage if a power outage/failure occurs \ 
during a session saving interval.
