RT1665: aes documentation.

Paul Green wrote a nice aes.pod file.
But we now encourage the EVP interface.
So I took his RT item and used it as impetus to add
the AES modes to EVP_EncryptInit.pod
I also noticed that rc4.pod has spurious references to some other
cipher pages, so I removed them.

RT2300: Clean up MD history (merged into RT1665)

Put HISTORY section only in EVP_DigestInit.pod. Also add words
to discourage use of older cipher-specific API, and remove SEE ALSO
links that point to them.

Make sure digest pages have a NOTE that says use EVP_DigestInit.

Review feedback:
More cleanup in EVP_EncryptInit.pod
Fixed SEE ALSO links in ripemd160.pod, sha.pod, mdc2.pod, blowfish.pod,
rc4.d, and des.pod.  Re-order sections in des.pod for consistency

Fix comments in ssltest.c: return value of 0 now means extension is
omitted and add_cb is not called for servers if the corresponding
extension is absent in ClientHello.

Test add_cb is not called if extension is not received.

Support separate parse and add callback arguments.
Add new callback so an application can free extension data.
Change return value for send functions so < 0 is an error 0
omits extension and > 0 includes it. This is more consistent
with the behaviour of other functions in OpenSSL.

Modify parse_cb handling so <= 0 is an error.

Make SSL_CTX_set_custom_cli_ext and SSL_CTX_set_custom_cli_ext argument
order consistent.

NOTE: these changes WILL break existing code.

Remove (now inaccurate) in line documentation.

Use "parse" and "add" for function and callback names instead of
"first" and "second".

Change arguments to callback so the extension type is unsigned int
and the buffer length is size_t. Note: this *will* break existing code.

Reject attempts to use extensions handled internally.

Add flags to each extension structure to indicate if an extension

duplicate extensions and unsolicited extensions and only send a
server extension if we have sent the corresponding client extension.

This change saves several EC routines from crashing when an EC_KEY is
