L<foo|foo> is sub-optimal If the xref is the same as the title,
which is what we do, then you only need L<foo>. This fixes all
1457 occurrences in 349 files. Approximately. (And pod used to
need both.)

This is a workaround so old that nobody remembers what buggy clients

Tor uses these values to implement a low-rent clone of RFC 5705 (which,
in our defense, we came up with before RFC 5705 existed). But now that
ssl_st is opaque, we need another way to get at them.
Includes documentation, with suitable warnings about not actually
using these functions.

On the server side, if you want to know which ciphers the client
offered, you had to use session->ciphers. But that field is no
longer visible, so we need a method to get at it.

Given the pervasive nature of TLS extensions it is inadvisable to run
OpenSSL without support for them. It also means that maintaining
the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
not well tested). Therefore it is being removed.

- Do not advise generation of DH parameters with dsaparam to save
computation time.
- Promote use of custom parameters more, and explicitly forbid use of
built-in parameters weaker than 2048 bits.
- Advise the callback to ignore <keylength> - it is currently called
with 1024 bits, but this value can and should be safely ignored by
servers.

The recent updates to libssl to enforce stricter return code checking, left
a small number of instances behind where return codes were being swallowed
(typically because the function they were being called from was declared as
void). This commit fixes those instances to handle the return codes more
appropriately.

SSL_SESSION_get_ticket_lifetime_hint. The latter has been reported as
required to fix Qt for OpenSSL 1.1.0. I have also added the former in order
to determine whether a ticket is present or not - otherwise it is difficult
to know whether a zero lifetime hint is because the server set it to 0, or
because there is no ticket.

There is no mechanism to do that at the moment - SSL_set_bio makes changes

This commit introduces two new API functions SSL_set_rbio() and
SSL_set_wbio(). These do the same job as SSL_set_bio() except they enable
you to manage the rbio and wbio individually.
