X509_STORE_add_cert and X509_STORE_add_crl are changed to return
success if the object to be added was already found in the store, rather
than returning an error.

Raise errors if empty or malformed files are read when loading certificates
and CRLs.

Remove NULL checks and allow a segv to occur.
Add error handing for all calls to X509_STORE_add_c{ert|tl}

Refactor these two routines into one.

Bring the unit test for duplicate certificates up to date using the test
framework.

Note that these guards are still needed around local header files that

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
for all how symbols belonging in our libraries are meant to be treated,
internally as well as publically.

The internals test programs access header files that aren't guarded by
the public __DECC_INCLUDE_PROLOGUE.H and __DECC_INCLUDE_EPILOGUE.H files,
and therefore have no idea what the naming convention is.  Therefore, we
need to specify that explicitely in the internals test programs, since
they aren't built with the same naming convention as the library they
belong with.

Trouble was that integer negation wasn't producing *formally* correct
result in platform-neutral sense. Formally correct thing to do is
-(int64_t)u, but this triggers undefined behaviour for one value that
would still be representable in ASN.1. The trigger was masked with
(int64_t)(0-u), but this is formally inappropriate for values other
than the problematic one. [Also reorder branches to favour most-likely
paths and harmonize asn1_string_set_int64 with asn1_get_int64].]

If EC support is enabled we should catch also EC_R_UNKNOWN_GROUP as an hint to
an unsupported algorithm/curve (e.g. if binary EC support is disabled).

Before this commit the issue arise for example if binary EC keys are added in
evptests.txt, and the test is run when EC is enabled but EC2m is disabled.

E.g. adding these lines to evptests.txt would reproduce the issue:

This adds a way to use the last byte of the buffer to change the
behavior of the server. The last byte is used so that the existing
corpus can be reused either without changing it, or just adding a single
byte, and that it can still be used by other projects.
