984d6c6052 Fix no-stdio build
Much related/similar work also done by
Ivan Nestlerode <ivan.nestlerode@sonos.com>

   +Replace FILE BIO's with dummy ops that fail.
   +Include <stdio.h> for sscanf() even with no-stdio (since the declaration
    is there). We rely on sscanf() to parse the OPENSSL_ia32cap environment
    variable, since it can be larger than a 'long'. And we don't rely on the
    availability of strtoull().
   +Remove OPENSSL_stderr(); not used.
   +Make OPENSSL_showfatal() do nothing (currently without stdio there's
    nothing we can do).
   +Remove file-based functionality from ssl/. The function
    prototypes were already gone, but not the functions themselves.
   +Remove unviable conf functionality via SYS_UEFI
   +Add fallback definition of BUFSIZ.
   +Remove functions taking FILE * from header files.
   +Add missing DECLARE_PEM_write_fp_const
   +Disable X509_LOOKUP_hash_dir(). X509_LOOKUP_file() was already compiled out,
    so remove its prototype.
   +Use OPENSSL_showfatal() in CRYPTO_destroy_dynlockid().
   +Eliminate SRP_VBASE_init() and supporting functions. Users will need to
    build the verifier manually instead.
   +Eliminate compiler warning for unused do_pk8pkey_fp().
   +Disable TEST_ENG_OPENSSL_PKEY.
   +Disable GOST engine as is uses [f]printf all over the place.
   +Eliminate compiler warning for unused send_fp_chars().

e481f9b90b Remove support for OPENSSL_NO_TLSEXT
Given the pervasive nature of TLS extensions it is inadvisable to run
OpenSSL without support for them. It also means that maintaining
the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
not well tested). Therefore it is being removed.

33f653adf3 New extension callback features.
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.

b362ccab5c Security framework.
Security callback: selects which parameters are permitted including
sensible defaults based on bits of security.

The "parameters" which can be selected include: ciphersuites,
curves, key sizes, certificate signature algorithms, supported
signature algorithms, DH parameters, SSL/TLS version, session tickets
and compression.

In some cases prohibiting the use of a parameters will mean they are
not advertised to the peer: for example cipher suites and ECC curves.
In other cases it will abort the handshake: e.g DH parameters or the
peer key size.

ac20719d99 Update custom TLS extension and supplemental data 'generate' callbacks to support sending an alert.
If multiple TLS extensions are expected but not received, the TLS extension and supplemental data 'generate' callbacks are the only chance for the receive-side to trigger a specific TLS alert during the handshake.

Removed logic which no-op'd TLS extension generate callbacks (as the generate callbacks need to always be called in order to trigger alerts), and updated the serverinfo-specific custom TLS extension callbacks to track which custom TLS extensions were received by the client, where no-ops for 'generate' callbacks are appropriate.

7b63c0fa8c Reorder inclusion of header files:
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.
