OCSP_RESPID was made opaque in 1.1.0, but no accessors were provided for
setting the name/key value for the OCSP_RESPID.

If OPENSSL_sk_insert() calls OPENSSL_realloc() and it fails, it was leaking
the originally allocated memory.

We should check the last BN_CTX_get() call to ensure that it isn't NULL
before we try and use any of the allocated BIGNUMs.

We were casting num_alloc to size_t in lots of places, or just using it in
a context where size_t makes more sense - so convert it. This simplifies
the code a bit.
Also tweak the style in stack.c a bit following on from the previous
commit

The internal SRP function t_fromb64() converts from base64 to binary. It
does not validate that the size of the destination is sufficiently large -
that is up to the callers. In some places there was such a check, but not
in others.
Add an argument to t_fromb64() to provide the size of the destination
buffer and validate that we don't write too much data. Also add some sanity
checks to the callers where appropriate.
With thanks to Shi Lei for reporting this issue.

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.

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.

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.

Ensure |BN_div| never gives negative zero in the no_branch code.
Have |bn_correct_top| fix |bn->neg| if the input is zero so that we
don't have negative zeros lying around.

MIPS[32|64]R6 is binary and source incompatible with previous MIPS ISA
specifications. Fortunately it's still possible to resolve differences
in source code with standard pre-processor and switching to trap-free
version of addition and subtraction instructions.

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.

User can make Windows openssl.exe to treat command-line arguments
and console input as UTF-8 By setting OPENSSL_WIN32_UTF8 environment
variable (to any value). This is likely to be required for data
interchangeability with other OSes and PKCS#12 containers generated
with Windows CryptoAPI.

For increments, the relaxed model is fine. For decrements, it's
recommended to use the acquire release model. We therefore go for the
latter.
