While *pval is usually a pointer in rare circumstances it can be a long
value. One some platforms (e.g. WIN64) where
sizeof(long) < sizeof(ASN1_VALUE *) this will write past the field.

*pval is initialised correctly in the rest of ASN1_item_ex_new so setting it
to NULL is unecessary anyway.

Thanks to Julien Kauffmann for reporting this issue.

Since source reformat, we ended up with some error reason string
definitions that spanned two lines.  That in itself is fine, but we
sometimes edited them to provide better strings than what could be
automatically determined from the reason macro, for example:

    {ERR_REASON(SSL_R_NO_GOST_CERTIFICATE_SENT_BY_PEER),
     "Peer haven't sent GOST certificate, required for selected ciphersuite"},

However, mkerr.pl didn't treat those two-line definitions right, and
they ended up being retranslated to whatever the macro name would
indicate, for example:

    {ERR_REASON(SSL_R_NO_GOST_CERTIFICATE_SENT_BY_PEER),
     "No gost certificate sent by peer"},

Clearly not what we wanted.  This change fixes this problem.

The macros BSWAP4 and BSWAP8 have statetemnt expressions

outside the macro call, generating warnings like this

We use GNU statement expressions in crypto/md32_common.h, surrounded
by checks that GNU C is indeed used to compile.  It seems that clang,
at least on Linux, pretends to be GNU C, therefore finds the statement
expressions and then warns about them.

The solution is to have clang be quiet about it.

ARM has optimized Cortex-A5x pipeline to favour pairs of complementary

Cortex-A53 performance by >40% (for CBC decrypt and CTR), it hurts
original r0p0. We favour later revisions, because one can't prevent
future from coming. Improvement on post-r0p0 Cortex-A57 exceeds 50%,
while new code is not slower on r0p0, or Apple A7 for that matter.

This engine is for VMS only, and isn't really part of the core OpenSSL
but rather a side project of its own that just happens to have tagged
along for a long time.  The reasons why it has remained within the
OpenSSL source are long lost in history, and there not being any real
reason for it to remain here, it's time for it to move out.

This side project will appear as a project in its own right, the
location of which will be announced later on.

With no more symlinks, there's no need for those variables, or the links
