version.

Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.

podlators 2.5.0 has switched to dying on POD syntax errors. This means
that a bunch of long-standing erroneous POD in the openssl documentation
now leads to fatal errors from pod2man, halting installation.

Unfortunately POD constraints mean that you have to sort numeric lists
in ascending order if they start with 1: you cannot do 1, 0, 2 even if
you want 1 to appear first. I've reshuffled such (alas, I wish there
were a better way but I don't know of one).

The version check for DTLS1_VERSION was redundant as
DTLS1_VERSION > TLS1_1_VERSION, however we do need to
check for DTLS1_BAD_VER for compatibility.

MD5 should use little endian order. Fortunately the only ciphersuite
affected is EXP-RC2-CBC-MD5 (TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5) which
is a rarely used export grade ciphersuite.

RISCs are picky and alignment granted by compiler for md_state can be
insufficient for SHA512.

Break dependency on uint64_t. It's possible to declare bits as
unsigned int, because TLS packets are limited in size and 32-bit
value can't overflow.
