The idea is to be able to add extension value lines directly on the
command line instead of through the config file, for example:

    openssl req -new -extension 'subjectAltName = DNS:dom.ain, DNS:oth.er' \
                     -extension 'certificatePolicies = 1.2.3.4'

Fixes #3311

Thank you Jacob Hoffman-Andrews for the inspiration

The simplifications that were made when Makefile.shared was removed
didn't work quite right.  Also, this is what we do on Unix and Windows
anyway, so this makes us more consistent across all platforms.

little easier, and wondering if others agree.

It is a hack, but it existed in the recently removed Makefile.shared,
and its use is documented in fuzz/README.md, so we cannot drop it now.

Previously, the RAND_DRBG_uninstantiate() call was not exactly inverse to
RAND_DRBG_instantiate(), because some important member values of the
drbg->ctr member where cleared. Now these values are restored internally.

A third shared DRBG is added, the so called master DRBG. Its sole purpose
is to reseed the two other shared DRBGs, the public and the private DRBG.
The randomness for the master DRBG is either pulled from the os entropy
sources, or added by the application using the RAND_add() call.

The master DRBG reseeds itself automatically after a given number of generate
requests, but can also be reseeded using RAND_seed() or RAND_add().
A reseeding of the master DRBG is automatically propagated to the public
and private DRBG. This construction fixes the problem, that up to now
the randomness provided by RAND_add() was added only to the public and
not to the private DRBG.

Normally we flush immediately after writing the ClientHello. However if
we are going to write a CCS immediately because we've got early_data to
come, then we should move the flush until after the CCS.
