Import OpenSSL 1.0.1 stable of 20110605:

this is sort of a sidegrade onto the release branch. Changes against the
last version imported:

*) Backport libcrypto audit of return value checking from HEAD, not
all cases can be covered as some introduce binary incompatibilities.
[Steve Henson]

*) Redirect RSA operations to FIPS module including keygen,
encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
[Steve Henson]

*) Add similar low level API blocking to ciphers.
[Steve Henson]

*) Low level digest APIs are not approved in FIPS mode: any attempt
to use these will cause a fatal error. Applications that *really* want
to use them can use the private_* version instead.
[Steve Henson]

*) Redirect cipher operations to FIPS module for FIPS builds.
[Steve Henson]

*) Redirect digest operations to FIPS module for FIPS builds.
[Steve Henson]

*) Update build system to add "fips" flag which will link in fipscanister.o
for static and shared library builds embedding a signature if needed.
[Steve Henson]

*) Output TLS supported curves in preference order instead of numerical
order. This is currently hardcoded for the highest order curves first.
This should be configurable so applications can judge speed vs strength.
[Steve Henson]

*) Add protection against ECDSA timing attacks as mentioned in the paper
by Billy Bob Brumley and Nicola Tuveri, see:

http://eprint.iacr.org/2011/232.pdf

[Billy Bob Brumley and Nicola Tuveri]

*) Add TLS v1.2 server support for client authentication.
[Steve Henson]

*) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
and enable MD5.
[Steve Henson]

*) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
FIPS modules versions.
[Steve Henson]

*) Add TLS v1.2 client side support for client authentication. Keep cache
of handshake records longer as we don't know the hash algorithm to use
until after the certificate request message is received.
[Steve Henson]

*) Initial TLS v1.2 client support. Add a default signature algorithms
extension including all the algorithms we support. Parse new signature
format in client key exchange. Relax some ECC signing restrictions for
TLS v1.2 as indicated in RFC5246.
[Steve Henson]

*) Add server support for TLS v1.2 signature algorithms extension. Switch
to new signature format when needed using client digest preference.
All server ciphersuites should now work correctly in TLS v1.2. No client
support yet and no support for client certificates.
[Steve Henson]

*) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
ciphersuites. At present only RSA key exchange ciphersuites work with
TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
and version checking.
[Steve Henson]

*) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
with this defined it will not be affected by any changes to ssl internal
structures. Add several utility functions to allow openssl application
to work with OPENSSL_NO_SSL_INTERN defined.
[Steve Henson]

*) Add SRP support.
[Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]

*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]

*) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
elliptic curve NIST-P224 with constant-time single point multiplication on
typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
(while EC_GROUP_new_curve_GFp() currently won't and prefers the more
flexible implementations).

The implementation requires support for the nonstandard type __uint128_t,
and so is disabled by default. To include this in your build of OpenSSL,
use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
and run "make depend" (or "make update").
[Emilia K<E4>sper <emilia.kasper@esat.kuleuven.be> (Google)]

*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
[Robin Seggelmann <seggelmann@fh-muenster.de>]

*) Add call to ENGINE_register_all_complete() to
ENGINE_load_builtin_engines(), so some implementations get used
automatically instead of needing explicit application support.
[Steve Henson]

*) Add support for TLS key exporter as described in RFC5705.
