278a33da3c VMS: be less picky when loading DSOs
The DSO API was picky about casing of symbol names on VMS.

There's really no reason to be that picky, it's mostly just annoying.
Therefore, we take away the possibility to flag for a choice, and will
instead first try to find a symbol with exact case, and failing that,
we try to find it in upper case.

135648bcd0 Fix mem leaks during auto-deinit
Certain functions are automatically called during auto-deinit in order
to deallocate resources. However, if we have never entered a function which
marks lib crypto as inited then they never get called. This can happen if
the user only ever makes use of a small sub-set of functions that don't hit
the auto-init code.

This commit ensures all such resources deallocated by these functions also
init libcrypto when they are initially allocated.

978ecbb08b Avoid EVP_PKEY_cmp() crash on EC keys without public component
Some hardware devices don't provide the public EC_POINT data. The only
way for X509_check_private_key() to validate that the key matches a
given certificate is to actually perform a sign operation and then
verify it using the public key in the certificate.

Maybe that can come later, as discussed in issue 1532. But for now let's
at least make it fail gracefully and not crash.

        Have |bn_correct_top| fix |bn->neg| if the input is zero so that we

216e8d9103 Improve the definition of STITCHED_CALL in e_rc4_hmac_md5.c
The definition of STITCHED_CALL relies on OPENSSL_NO_ASM.  However,
when a configuration simply lacks the assembler implementation for RC4
(which is where we have implemented the stitched call), OPENSSL_NO_ASM
isn't implemented.  Better, then, to rely on specific macros that
indicated that RC4 (and MD5) are implemented in assembler.

For this to work properly, we must also make sure Configure adds the
definition of RC4_ASM among the C flags.

2338ad8885 Fix math in BN_bn2dec comment.
The bound on log(2)/3 on the second line is incorrect and has an extra
zero compared to the divisions in the third line. log(2)/3 = 0.10034...
which is bounded by 0.101 and not 0.1001. The divisions actually
correspond to 0.101 which is fine. The third line also dropped a factor
of three.

The actual code appears to be fine. Just the comments are wrong.

cdb2a60347 Internalizes SCT_verify and removes SCT_verify_v1
SCT_verify is impossible to call through the public API (SCT_CTX_new() is
not part of the public API), so rename it to SCT_CTX_verify and move it
out of the public API.

SCT_verify_v1 is redundant, since SCT_validate does the same verification
(by calling SCT_verify) and more. The API is less confusing with a single
verification function (SCT_validate).
