(trunk libT) fix magnet link crash in peer-msgs.c's updateDesiredRequestCount() reported by quinx in the forums.
...
In some odd cases (such as if unchoked without having shown interest), the code could dividing a number by the torrent's block size without checking to see if the torrent had its metadata yet. This caused a division by zero because a magnet torrent's blocksize is unset until the metadata is downloaded.

(trunk libT) CPU improvement in torrent.c's torrentInit()
...
Add the new torrent to the session's torrent list by prepending it instead of appending it. That way we don't have to walk the list in order to add it. tr_session.torrentList is an unordered list, so there's no real difference between prepending and appending.

(trunk libT) #4209 "Shortcut UDP tracker test" -- prioritize the UDP handler functions based on frequency (uTP, DHT, UTP tracker) as outlined by jch in comment:5. Also, don't call the uTP or DHT handlers when uTP or DHT is disabled in the system preferences.
...
To avoid the function call overhead described by jch, instead of calling tr_sessionIsUTPEnabled() and tr_sessionIsDHTEnabled(), we test for WITH_UTP to be defined and test the tr_session.isUTPEnabled and tr_session.isDHTEnabled flags directly.

(trunk libT) #4209 "Shortcut UDP tracker test" -- the goal of #4209 is to minimize the cost of the UDP event callback function, so apply the heap pruning eye to that by removing an unnecessary malloc/free call there.
...
Previously we allocated a 4096 character buffer each time; now we allocate it on the stack. It seems all the distros and OS flavors that Transmission runs on have multi-MB default stack sizes, so a hardwired 4K array should be safe.
