The declaration of bio_type_lock is independent of no-sock so should not be
inside OPENSSL_NO_SOCK guards.

Currently on every BIO mem read operation the remaining data is reallocated.
This commit solves the issue.
BIO mem structure includes additional pointer to the read position.
On every read the pointer moves instead of reallocating the memory for the remaining data.
Reallocation accures before write and some ioctl operations, if the read pointer doesn't point on the beginning of the buffer.
Also the flag is added to rewind the read pointer without losing the data.

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.

Move the the BIO_METHOD and BIO structures into internal header files,
provide appropriate accessor methods and update all internal code to use
the new accessors where appropriate.

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.
