cbddeebe49 Some interfaces may have IPv6 addresses even if an IPv6 address is not
"configured on the local system". Whatever that means. Example that is biting
me is loopback has ::1 as an address, but the network interface is v4 only.

fcd9c8c014 Fix pointer size issues on VMS
On VMS, the C compiler can work with 32-bit and 64-bit pointers, and
the command line determines what the initial pointer size shall be.

However, there is some functionality that only works with 32-bit
pointers.  In this case, it's gethostbyname(), getservbyname() and
accompanying structures, so we need to make sure that we define our
own pointers as 32-bit ones.

Furthermore, there seems to be a bug in VMS C netdb.h, where struct
addrinfo is always defined with 32-bit pointers no matter what, but
the functions handling it are adapted to the initial pointer size.
This leads to pointer size warnings when compiling with
/POINTER_SIZE=64.  The workaround is to force struct addrinfo to be
the 64-bit variant if the initial pointer size is 64.

1288f26fb9 RT4310: Fix varous no-XXX builds
When OPENSSL_NO_ASYNC is set, make ASYNC_{un,}block_pause() do nothing.
This prevents md_rand.c from failing to build. Probably better to do it
this way than to wrap every instance in an explicit #ifdef.

A bunch of new socket code got added to a new file crypto/bio/b_addr.c.
Make it all go away if OPENSSL_NO_SOCK is defined.

Allow configuration with no-ripemd, no-ts, no-ui
We use these for the UEFI build.

Also remove the 'Really???' comment from no-err and no-locking. We use
those too.

We need to drop the crypto/engine directory from the build too, and also
set OPENSSL_NO_ENGINE

6faffd0ad2 Better workaround for VMS getnameinfo() bug
The actual bug with current getnameinfo() on VMS is not that it puts
gibberish in the service buffer, but that it doesn't touch it at all.
The gibberish we dealt with before was simply stuff that happened to
be on the stack.

It's better to initialise the service buffer properly (with the empty
string) and check if it's still an empty string after the
getnameinfo() call, and fill it with the direct numerical translation
of the raw port if that's the case.

d40cf9bc9c VMS getnameinfo() seems to have a bug with returned service string
It seems like it gives back gibberish.  If we asked for a numeric
service, it's easy to check for a digit in the first position, and
if there isn't any, rewrite it using older methods.

28a0841bf5 Refactoring BIO: add wrappers around sockaddr et al
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.
