Add no-async option to Configure that forces ASYNC_NULL.
Related to RT1979
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.

--prefix is now exclusively used for software and manual installation.
--openssldir is not exclusively used as a default location for certs,
keys and the default openssl.cnf.

This change is made to bring clarity, to have the two less
intertwined, and to be more compatible with the usual ways of software
installation.

Please change your habits and scripts to use --prefix rather than
--openssldir for installation location now.

util/mk1mf.pl was relying on the platform having the 'debug-' prefix
for doing a debug build.  Since the setup of targets has changed, this
is no longer true.  However, it can look for '--debug' in the command
line options.

With the new testing framework, building a test target with mk1mf.pl
becomes a very simple thing.  And especially, no more need to do the
amount of hackery in unix.pl we did.

Also, some tests need a working apps/CA.pl as well as rehashed certs
in certs/demo.  So, move the code creating those files so it gets done
regardless, not just in non-mk1mf environments.

Given the pervasive nature of TLS extensions it is inadvisable to run
OpenSSL without support for them. It also means that maintaining
the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
not well tested). Therefore it is being removed.

When building on Unix, there are times when the 'EX_LIB' MINFO variable
contains valuable information.  Make sure to take care of it.

fixrules in util/pl/unix.pl was previously changed with a simpler fix of
rules, with a comment claiming that's compatible with -j.  Unfortunately,
this breaks multiline rules and doesn't change anything for single line
rules.  While at it, do not prefix pure echo lines with a 'cd $(TEST_D) &&',
as that's rather silly.

Remove support for SHA0 and DSS0 (they were broken), and remove
the ability to attempt to build without SHA (it didn't work).
For simplicity, remove the option of not building various SHA algorithms;
you could argue that SHA_224/256/384/512 should be kept, since they're
like crypto algorithms, but I decided to go the other way.
So these options are gone:
	GENUINE_DSA         OPENSSL_NO_SHA0
	OPENSSL_NO_SHA      OPENSSL_NO_SHA1
	OPENSSL_NO_SHA224   OPENSSL_NO_SHA256
