If no serverinfo extension is found in some cases, do not abort the handshake,
but simply omit/skip that extension.

Check for already-registered serverinfo callbacks during serverinfo
registration.

Update SSL_CTX_use_serverinfo() documentation to mention the need to reload the
same serverinfo per certificate, for servers with multiple server certificates.

Fix some of the variables to be (s)size_t, so that more than 1GB of
secure memory can be allocated. The arena has to be a power of 2, and
2GB fails because it ends up being a negative 32-bit signed number.

The |too_late| flag is not strictly necessary; it is easy to figure
out if something is secure memory by looking at the arena. As before,
secure memory allocations will not fail, but now they can be freed
correctly. Once initialized, secure memory can still be used, even if
allocations occured before initialization.

This adds an explicit limit to the size of an X509_NAME structure. Some
part of OpenSSL (e.g. TLS) already effectively limit the size due to
restrictions on certificate size.

The srp application created an uninitialised DB_ATTR object and then
passed it to the load_index function which attempted to read it. A
DB_ATTR object only contains a single field called "unique_subject".
AFAICT this attribute is unused in the SRP case, and therefore it would be
better to pass a NULL DB_ATTR to load_index (which handles that case
gracefully).

We should only copy parameters and keys if the group is set. Otherwise
they don't really make any sense. Previously we copied the private key
regardless of whether the group was set...but if it wasn't a NULL ptr
deref could occur. It's unclear whether we could ever get into that
situation, but since we were already checking it for the public key we
should be consistent.

When compiling all other C files, rely on the compiler to
automatically pick up the name translation information from the header
files __DECC_INCLUDE_{PRO,EPI}LOGUE.H.

Reviewed-by: Andy Polyakov <appro@openssl.org>

With DEC C on VMS, you can use __DECC_INCLUDE_PROLOGUE.H and
__DECC_INCLUDE_EPILOGUE.H to include some DEC C specific features or
pragmas without having to touch the other header files.

It seems, however, that the current version of the compiler requires
the file names to be upcased, or it doesn't handle them quite right.

Currently we can get all block ciphers with
	EVP_get_cipherbyname("<alg_name>-<block-mode-name>")
for example, by names "aes-128-ecb" or "des-ede-cbc".
I found a problem with des-ede-ecb and des-ede3-ecb ciphers as
they can be accessed only with names:
	EVP_get_cipherbyname("des-ede")
	EVP_get_cipherbyname("des-ede3")
It breaks the general concept.

In this patch I add aliases which allow to use names:
	EVP_get_cipherbyname("des-ede-ecb")
	EVP_get_cipherbyname("des-ede3-ecb")
in addition to the currently used names.
