Now that we attempt to send early data in the first TCP packet along with
the ClientHello, the documentation for SSL_write_early_data() needed a
tweak.

We don't keep track of the number of bytes written between in the
SSL_write_ex() call and the subsequent flush. If the flush needs to be
retried then we will have forgotten how many bytes actually got written.
The simplest solution is to just disable it for this scenario.

We'd like the first bit of early_data and the ClientHello to go in the
same TCP packet if at all possible to enable things like TCP Fast Open.
Also, if you're only going to send one block of early data then you also
don't need to worry about TCP_NODELAY.

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

It is a hack, but it existed in the recently removed Makefile.shared,

Previously, the RAND_DRBG_uninstantiate() call was not exactly inverse to
RAND_DRBG_instantiate(), because some important member values of the

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.
