Because different platforms have different levels of support for IPv6,
different kinds of sockaddr variants, and some have getaddrinfo et al
while others don't, we could end up with a mess if ifdefs, duplicate
code and other maintainance nightmares.
Instead, we're introducing wrappers around the common form for socket
communication:
BIO_ADDR, closely related to struct sockaddr and some of its variants.
BIO_ADDRINFO, closely related to struct addrinfo.
With that comes support routines, both convenient creators and
accessors, plus a few utility functions:
BIO_parse_hostserv, takes a string of the form host:service and
splits it into host and service. It checks for * in both parts, and
converts any [ipv6-address] syntax to ust the IPv6 address.
BIO_lookup, looks up information on a host.
All routines handle IPv4 (AF_INET) and IPv6 (AF_INET6) addresses, and
there is support for local sockets (AF_UNIX) as well.

Now that we have the foundation for the "unified" build scheme in
place, we add build.info files. They have been generated from the
Makefiles in the same directories. Things that are platform specific
will appear in later commits.
Reviewed-by: Andy Polyakov <appro@openssl.org>
The "unified" build scheme revolves around small information files,
build.info, which each describe their own bit of everything that needs
to be built, using a mini-language described in Configurations/README.
The information in build.info file contain references to source files
and final result. Object files are not mentioned at all, they are
simply from source files. Because of this, all the *_obj items in
Configurations/*.conf are renamed to *_asm_src and the files listed
in the values are change from object files to their corresponding
source files. For the sake of the other build schemes, Configure
generates corresponding *_obj entries in %target.
Furthermore, the "unified" build scheme supports having a build
directory tree separate from the source directry tree.
All paths in a build.info file is assumed to be relative to its
location, either within the source tree or within the build tree.

When auxiliary data contains only reject entries, continue to trust
self-signed objects just as when no auxiliary data is present.
This makes it possible to reject specific uses without changing
what's accepted (and thus overring the underlying EKU).

As a side-effect of opaque x509, ex_flags were looked up too early,
before additional policy cache updates.
Reviewed-by: Dr. Stephen Henson <steve@openssl.org>
The lflags configuration had a weird syntax with a % as separator. If
it was present, whatever came before ended up as PEX_LIBS in Makefile
(usually, this is LDFLAGS), while whatever came after ended up as
EX_LIBS.
This change splits that item into lflags and ex_libs, making their use
more explicit.
Also, PEX_LIBS in all the Makefiles are renamed to LDFLAGS.

By default X509_check_trust() trusts self-signed certificates from
the trust store that have no explicit local trust/reject oids
encapsulated as a "TRUSTED CERTIFICATE" object. (See the -addtrust
and -trustout options of x509(1)).
This commit adds a flag that makes it possible to distinguish between
that implicit trust, and explicit auxiliary settings.
With flags |= X509_TRUST_NO_SS_COMPAT, a certificate is only trusted
via explicit trust settings.

Historically OpenSSL only ever generated DH parameters based on "safe"
primes. More recently (in version 1.0.2) support was provided for
generating X9.42 style parameter files such as those required for RFC
5114 support. The primes used in such files may not be "safe". Where an
application is using DH configured with parameters based on primes that
are not "safe" then an attacker could use this fact to find a peer's
private DH exponent. This attack requires that the attacker complete
multiple handshakes in which the peer uses the same DH exponent.
A simple mitigation is to ensure that y^q (mod p) == 1
