VMS: tell the C compiler to use the ISO C94 standard

The current version of the VMS compiler provides C99 features,
strictly language wise.  Unfortunately, even the most recent standard
library isn't fully updated for that standard, so we need to use an
earlier standard that the compiler supports.

Most importantly, this affects the __STDC_VERSION__ value, which the
compiler unfortunately currently defaults to 199901L.  With this
change we won't have to give VMS special treatment when looking for
features based on that macro.

executables or perl scripts.  But what about scripts in some other
language?  Or what about running entirely external programs?  The
answer is certainly not to add new functions to access scripts for
each language or wrapping all the external program calls in our magic!

Instead, this adds a new functions, cmd(), which is useful to access
executables and scripts in a more generalised manner.  app(), test(),
fuzz(), perlapp() and perltest() are rewritten in terms of cmd(), and

Fix encrypt-then-mac implementation for DTLS

OpenSSL 1.1.0 will negotiate EtM on DTLS but will then not actually *do* it.

If we use DTLSv1.2 that will hopefully be harmless since we'll tend to use
an AEAD ciphersuite anyway. But if we're using DTLSv1, then we certainly
will end up using CBC, so EtM is relevant — and we fail to interoperate with
anything that implements EtM correctly.

Fixing it in HEAD and 1.1.0c will mean that 1.1.0[ab] are incompatible with
1.1.0c+... for the limited case of non-AEAD ciphers, where they're *already*
incompatible with other implementations due to this bug anyway. That seems
reasonable enough, so let's do it. The only alternative is just to turn it
off for ever... which *still* leaves 1.0.0[ab] failing to communicate with
non-OpenSSL implementations anyway.
