fab79c5d25 libratbox: Fix undefined behaviour advancing pointer beyond end of array. 
The C standard does not allow constructing pointers beyond one past the end
of an array. Therefore, if size is an unsigned type (size_t), then
buf + size is never less than buf.

Clang on 32-bit took advantage of the undefined behaviour, causing
segfaults.

Lightly tested.

362ef2d9ee openssl: Improve security using options recommanded by Argure. 
Note that these are not available in old versions of OpenSSL (like FreeBSD
9.x base OpenSSL), so allow them to be missing.

A side effect may be slightly higher CPU consumption and network traffic.

fabc3174fe openssl: Set some sort of session id context. 
Without a session id context and if client certificates are used, OpenSSL
fails the handshake if an attempt is made to reuse an old session. Various
clients could not reconnect after a disconnection because of this.

See https://bugzilla.mozilla.org/show_bug.cgi?id=858394#c34 for a bug
report.

320d34a606 libratbox/crypt: fix difference from glibc in sha256_crypt() 
rb_crypt() was generating different SHA256 ($5$) hashes than glibc,
making hashes generated with charybdis unusable in ratbox and other
software, and vice versa.

797a29f353 libratbox: Allow defer_accept on FreeBSD. 
Note that you must have options ACCEPT_FILTER_DATA in your kernel
configuration or load the accf_data kernel module. The functionality is
not in the GENERIC kernel.

77cb59b319 libratbox: add support for TCP_DEFER_ACCEPT on linux 
This allows for some further hardening against synflooding and connection flooding
where no data is actually sent, as the kernel will simply ignore those connections
(well, as far as the ircd is concerned anyway).

7247337afa Add certfp support to libratbox and ssld. 
This lets a user connect with a client certificate, and
passes the certificate's fingerprint to ircd, which
currently just notices it to the user.

A new ssld->ircd message 'F' is used to pass on the
fingerprint.

This is only for OpenSSL for now, not GNUTLS.
