When handling ECDH check to see if the curve is "custom" (X25519 is
currently the only curve of this type) and instead of setting a curve
NID just allocate a key of appropriate type.

Add encoded point ctrl support for other curves: this makes it possible
to handle X25519 and other EC curve point encoding in a similar way
for TLS.

Originally new-line was suppressed, because double new-line was
observed under wine. But it appears rather to be a wine bug,
because on real Windows new-line is much needed.

Problem was introduced in 299ccadc
as future extension, i.e. at this point it wasn't an actual problem,
because uninitialized capability bit was not actually used.

In practice, CT isn't really functional without EC anyway, as most logs
use EC keys. So, skip loading the log list with no-ec, and skip CT tests
completely in that conf.

Commit 417be660 broken BIO_new_accept() by changing the definition of the
macro BIO_set_accept_port() which stopped acpt_ctrl() from calling
BIO_parse_hostserv(). This commit completes the series of changes
initiated in 417be660.

Updated pods to reflect new definition introduced by 417be660.
