Port Ben's parallell Makefile hack to VMS

As far as I know, there is no MMS / MMK with parallellism today.
However, it might be added in the future (perhaps in MMK at least), so
we may as well prepare for it now.

Small primes are primes too.

Previously, BN_is_prime_fasttest_ex, when doing trial-division, would
check whether the candidate is a multiple of a number of small primes
and, if so, reject it. However, three is a multiple of three yet is
still a prime number.

This change accepts small primes as prime when doing trial-division.

X509_STORE_add_cert and X509_STORE_add_crl are changed to return

VMS: Copy DECC inclusion epi- and prologues to internals

Because many of our test programs use internal headers, we need to make
sure they know how, exactly, to mangle the symbols.  So far, we've done
so by specifying it in the affected test programs, but as things change,
that will develop into a goose chase.  Better then to declare once and

internally as well as publically.

need to specify that explicitely in the internals test programs, since
