Revert SO_???TIMEO-based STARTTLS timeout handling.

This reverts commits 47c05b10018f5ec7493e4bd9f521aaa18d96f1e2
and 72ce8bce8dd655b6aefa33d0a74e883dad5202b5, the code isn't portable,
for instance, Solaris does not support SO_RCVTIMEO/SO_SNDTIMEO.
These socket-level options are known, but Solaris returns EAFNOSUPPORT.

+- fix STARTTLS timeouts by setting socket timings
+  possibly using a different structure than an int to save the fd
+  and SSL context -- and then also timeout?
+  Or just make set_timeout take an optional fd, which, when != -1,
+  also sets the socket timeouts?
+
+- make SSLv2 removal dependent on openssl configuration
+  (see Debian FTBFS bug for how to detect that in configure)
+
+- make --with-ssl default?
