Some #include statements were not properly protected. This will go unnoted
on most systems as openssl/comp.h tends to be installed as a system header
file by default but may become visible when cross compiling.

knock-on work than expected - they've been extracted into a patch

of handshake failure
2. Changes to x509_certificate_type function (crypto/x509/x509type.c) to
make it recognize GOST certificates as EVP_PKT_SIGN|EVP_PKT_EXCH
(required for s3_srvr to accept GOST client certificates).
3. Changes to EVP
- adding of function EVP_PKEY_CTX_get0_peerkey
- Make function EVP_PKEY_derive_set_peerkey work for context with
ENCRYPT operation, because we use peerkey field in the context to
pass non-ephemeral secret key to GOST encrypt operation.
- added EVP_PKEY_CTRL_SET_IV control command. It is really
GOST-specific, but it is used in SSL code, so it has to go
in some header file, available during libssl compilation
4. Fix to HMAC to avoid call of OPENSSL_cleanse on undefined data
5. Include des.h if KSSL_DEBUG is defined into some libssl files, to
make debugging output which depends on constants defined there, work
and other KSSL_DEBUG output fixes
6. Declaration of real GOST ciphersuites, two authentication methods
SSL_aGOST94 and SSL_aGOST2001 and one key exchange method SSL_kGOST
7. Implementation of these methods.
8. Support for sending unsolicited serverhello extension if GOST
ciphersuite is selected. It is require for interoperability with
CryptoPro CSP 3.0 and 3.6 and controlled by
SSL_OP_CRYPTOPRO_TLSEXT_BUG constant.
This constant is added to SSL_OP_ALL, because it does nothing, if
non-GOST ciphersuite is selected, and all implementation of GOST
include compatibility with CryptoPro.
9. Support for CertificateVerify message without length field. It is
another CryptoPro bug, but support is made unconditional, because it
does no harm for draft-conforming implementation.
10. In tls1_mac extra copy of stream mac context is no more done.
When I've written currently commited code I haven't read
EVP_DigestSignFinal manual carefully enough and haven't noticed that
it does an internal digest ctx copying.
This implementation was tested against
1. CryptoPro CSP 3.6 client and server
2. Cryptopro CSP 3.0 server

(draft-rescorla-tls-opaque-prf-input-00.txt), and do some cleanups and
bugfixes on the way. In particular, this fixes the buffer bounds
checks in ssl_add_clienthello_tlsext() and in ssl_add_serverhello_tlsext().
Note that the opaque PRF Input TLS extension is not compiled by default;
see CHANGES.

This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).
In some cases the ciphersuite list generated from a given string is
affected by this change. I hope this is just in those cases where the
previous behaviour did not make sense.

des_old.h redefines crypt:
#define crypt(b,s)\
DES_crypt((b),(s))
This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().
Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

like Malloc, Realloc and especially Free conflict with already existing names
on some operating systems or other packages. That is reason enough to change
the names of the OpenSSL memory allocation macros to something that has a
better chance of being unique, like prepending them with OPENSSL_.
This change includes all the name changes needed throughout all C files.
