It turns out that AT_SECURE may be defined through other means than
our inclusion of sys/auxv.h, so to be on the safe side, we define our
own guard and use that to determine if getauxval() should be used or
not.

We were setting a limit of SSL3_RT_MAX_PLAIN_LENGTH on the size of the
ClientHello. AFAIK there is nothing in the standards that requires this
limit.

The limit goes all the way back to when support for extensions was first
added for TLSv1.0. It got converted into a WPACKET max size in 1.1.1. Most
likely it was originally added to avoid the complexity of having to grow
the init_buf in the middle of adding extensions. With WPACKET this is
irrelevant since it will grow automatically.

This issue came up when an attempt was made to send a very large
certificate_authorities extension in the ClientHello.

We should just remove the limit.

The check_key_level() function currently fails when the public key
cannot be extracted from the certificate because its algorithm is not
supported.  However, the public key is not needed for the last
certificate in the chain.

This change moves the check for level 0 before the check for a
non-NULL public key.

For background, this is the TPM 1.2 endorsement key certificate.
I.e., this is a real application with millions of certificates issued.
The key is an RSA-2048 key.

The TCG (for a while) specified

     Public Key Algorithm: rsaesOaep

rather than the commonly used

     Public Key Algorithm: rsaEncryption

because the key is an encryption key rather than a signing key.
The X509 certificate parser fails to get the public key.

While stereotyped repetitions are frowned upon in literature, they
serve a useful purpose in manual pages, because it is easier for
the user to find certain information if it is always presented in
the same way. For that reason, this commit harmonizes the varying
formulations in the HISTORY section about which functions, flags,
etc. were added in which OpenSSL version.

It also attempts to make the pod files more grep friendly by
avoiding to insert line breaks between the symbol names and the
corresponding version number in which they were introduced
(wherever possible). Some punctuation and typographical errors
were fixed on the way.
