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.

Every DRBG now supports automatic reseeding not only after a given
number of generate requests, but also after a specified time interval.

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.

The CCS may be sent at different times based on whether or not we
sent an HRR earlier. In order to make that decision this commit
also updates things to make sure we remember whether an HRR was
used or not.

The new ServerHello format is essentially now the same as the old TLSv1.2
one, but it must additionally include supported_versions. The version
field is fixed at TLSv1.2, and the version negotiation happens solely via
supported_versions.

If OPENSSL_init_crypto() hasn't been called yet when ERR_get_state()
is called, it need to be called early, so the base initialization is
done. On some platforms (those who support DSO functionality and
don't define OPENSSL_USE_NODELETE), that includes a call of
ERR_set_mark(), which calls this function again.
Furthermore, we know that ossl_init_thread_start(), which is called
later in ERR_get_state(), calls OPENSSL_init_crypto(0, NULL), except
that's too late.
Here's what happens without an early call of OPENSSL_init_crypto():
=> ERR_get_state():
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated.
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# Here, base_inited is set to 1
# before ERR_set_mark() call
=> ERR_set_mark():
=> ERR_get_state():
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated!!!!!
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
<=
=> CRYPTO_thread_set_local():
<=
<=
<=
<= 1
<=
=> CRYPTO_thread_set_local() # previous value removed!
<=
Result: double allocation, and we have a leak.
By calling the base OPENSSL_init_crypto() early, we get this instead:
=> ERR_get_state():
=> OPENSSL_init_crypto():
# Here, base_inited is set to 1
# before ERR_set_mark() call
=> ERR_set_mark():
=> ERR_get_state():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
=> CRYPTO_THREAD_get_local():
<= NULL;
# no state is found, so it gets allocated
# let's assume we got 0xDEADBEEF
=> ossl_init_thread_start():
=> OPENSSL_init_crypto():
# base_inited is 1,
# so no more init to be done
<= 1
<= 1
=> CRYPTO_thread_set_local():
<=
<=
<=
<= 1
=> CRYPTO_THREAD_get_local():
<= 0xDEADBEEF
<= 0xDEADBEEF
Result: no leak.
