Some time ago, we had a ex_libs configuration setting that could be
divided into lflags and ex_libs. These got divided in two settings,
lflags and ex_libs, and the former was interpreted to be general
linking flags.
Unfortunately, that conclusion wasn't entirely accurate. Most of
those linking were meant to end up in a very precise position on the
linking command line, just before the spec of libraries the linking
depends on.
Back to the drawing board, we're diving things further, now having
lflags, which are linking flags that aren't depending on command line
position, plib_lflags, which are linking flags that should show up just
before the spec of libraries to depend on, and finally ex_libs, which
is the spec of extra libraries to depend on.
Also, documentation is changed in Configurations/README. This was
previously forgotten.

Add no-async option to Configure that forces ASYNC_NULL.

An embedded system or replacement C library (e.g. musl or uClibc)
may not support the *context APIs that are needed for async operation.
Compiles with musl. Ran unit tests, async tests skipped as expected.

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.
