Rtorrent: some ssl trackers timeout with curl 7.55.1

[chargr]

announcing to some ssl trackers appears to timeout (and max a cpu core) with curl 7.55.1
using curl from cli with the same requests did not timeout and got a valid response in < 2 seconds.
downgrading to 7.54.1 fixed the issue for me (this was arch linux)

Same issue for me with curl version 7.55+, Debian 9.

I have timeout with non-ssl trackers as well.

i also have timeouts on ssl and non-ssl

Also had timeouts accompanied by one cpu core maxed out. Downgrading curl to 7.54.1 seems to fix it here as well.

Same for me on gentoo with 7.55.0.

[SJ50]

updated cur to 7.55.1-2 on arch linux and it seem to fix the issue, at least non-ssl.
I do not have ssl tracker.

Will be patched in the next cURL release.
