Specify -f is for compilation flags. Add -d to synopsis section.

Closes #77.

Fix eckey_priv_encode to return an error on failure of i2d_ECPrivateKey.

There are certainly many more constifiable strings in the various
interfaces, which I hope to get to eventually.

Gets rid of this;

Fix typo that stopped SSL_CTX_get_{first,next}_certificate from working.

When looking for an extension we need to set the last found
position to -1 to properly search all extensions.

PR#3309.

Keep copy of any host, path and port values allocated by
OCSP_parse_url and free as necessary.

Treat a zero length passed to ssleay_rand_add a no op: the existing logic
zeroes the md value which is very bad. OpenSSL itself never does this
internally and the actual call doesn't make sense as it would be passing
zero bytes of entropy.

A missing bounds check in the handling of the TLS heartbeat extension
can be used to reveal up to 64k of memory to a connected client or
server.

Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
preparing the fix (CVE-2014-0160)

Enable TLS padding extension using official value from:

Use bufsiz - 1 not BUFSIZ - 1 when prompting for a password in
the openssl utility.

New -hash_old to generate CRL hashes using old
(before OpenSSL 1.0.0) algorithm.

A short PEM encoded sequence if passed to the BIO, and the file
had 2 \n following would fail.

PR#3289

Add additional check to catch this in ASN1_item_verify too.
(cherry picked from commit 66e8211c0b1347970096e04b18aa52567c325200)

Allow setting of security level in cipher string using the
@SECLEVEL=N syntax.

Since ssltest needs to test low security ciphersuites and keys
set security level to zero so they aren't rejected.

Add a debugging security callback option to s_client/s_server. This will
print out each security parameter as it is accepted or rejected.

Security callback: selects which parameters are permitted including
sensible defaults based on bits of security.

The "parameters" which can be selected include: ciphersuites,
curves, key sizes, certificate signature algorithms, supported
signature algorithms, DH parameters, SSL/TLS version, session tickets
and compression.

In some cases prohibiting the use of a parameters will mean they are
not advertised to the peer: for example cipher suites and ECC curves.
In other cases it will abort the handshake: e.g DH parameters or the
peer key size.
