Harmonize the make variables across all known platforms families

The make variables LIB_CFLAGS, DSO_CFLAGS and so on were used in
addition to CFLAGS and so on.  This works without problem on Unix and
Windows, where options with different purposes (such as -D and -I) can
appear anywhere on the command line and get accumulated as they come.
This is not necessarely so on VMS.  For example, macros must all be
collected and given through one /DEFINE, and the same goes for
inclusion directories (/INCLUDE).

So, to harmonize all platforms, we repurpose make variables starting
with LIB_, DSO_ and BIN_ to be all encompassing variables that
collects the corresponding values from CFLAGS, CPPFLAGS, DEFINES,
INCLUDES and so on together with possible config target values
specific for libraries DSOs and programs, and use them instead of the
general ones everywhere.

This will, for example, allow VMS to use the exact same generators for
generated files that go through cpp as all other platforms, something
that has been impossible to do safely before now.

DRBG: make the derivation function the default for ctr_drbg

The NIST standard presents two alternative ways for seeding the
CTR DRBG, depending on whether a derivation function is used or not.
In Section 10.2.1 of NIST SP800-90Ar1 the following is assessed:

  The use of the derivation function is optional if either an
  approved RBG or an entropy source provides full entropy output
  when entropy input is requested by the DRBG mechanism.
  Otherwise, the derivation function shall be used.

Since the OpenSSL DRBG supports being reseeded from low entropy random
sources (using RAND_POOL), the use of a derivation function is mandatory.
For that reason we change the default and replace the opt-in flag
RAND_DRBG_FLAG_CTR_USE_DF with an opt-out flag RAND_DRBG_FLAG_CTR_NO_DF.

the CCS and Finished. Historically we always calculated the Finished MAC
when we processed the CCS. However to deal with NPN we also calculated it
when we receive the Finished message. Really this should only have been
done if we hand negotiated NPN.

This simplifies the code to only calculate the MAC when we receive the
Finished. In 1.1.1 we need to do it this way anyway because there is no
CCS (except in middlebox compat mode) in TLSv1.3.

Coincidentally, this commit also fixes the fact that no-nextprotoneg does
not currently work in master.
