EVP_MDs are always const, so stacks of them should be too. This silences
a warning about type punning on OpenBSD.

Add const qualifiers to lots of SRP stuff. This started out as an effort
to silence some "type-punning" warnings on OpenBSD...but the fix was to
have proper const correctness in SRP.

Previously we would try %RANDFILE%, then %HOME% and finally "C:".
Unfortunately this often ends up being "C:" which the user may not
have write permission for.
Now we try %RANDFILE% first, and then the same set of environment vars
as GetTempFile() uses, i.e. %TMP%, then %TEMP%, %USERPROFILE% and
%SYSTEMROOT%. If all else fails we fall back to %HOME% and only then "C:".

Before the addition of this function, it was impossible to read the
symmetric key from an EVP_PKEY_HMAC type EVP_PKEY.

Previously EVP_EncodeUpdate returned a void. However there are a couple
of error conditions that can occur. Therefore the return type has been
changed to an int, with 0 indicating error and 1 indicating success.

This is useful in Linux kernel context, in cases data happens
to be fragmented and processing can take multiple calls.

use strict would have caught a number of historical bugs in the perlasm
code, some in the repository and some found during review. It even found
a fresh masm-only bug (see below).
This required some tweaks. The "single instance is enough" globals got
switched to proper blessed objects rather than relying on symbolic refs.
A few types need $opcode passed in as a result.
The $$line thing is a little bit of a nuisance. There may be a clearer
pattern to use instead.
This even a bug in the masm code.
9b634c9b37 added logic to make labels
global or function-global based on whether something starts with a $,
seemingly intended to capture the $decor setting of '$L$'. However, it
references $ret which is not defined in label::out. label::out is always
called after label::re, so $ret was always the label itself, so the line
always ran.
I've removed the regular expression so as not to change the behavior of
the script. A number of the assembly files now routinely jump across
functions, so this seems to be the desired behavior now.

The selector field could be omitted because it has a DEFAULT value.
In this case *sfld == NULL (sfld can never be NULL). This was not
noticed because this was never used in existing ASN.1 modules.

The function a2i_ASN1_STRING can encounter an error after already
allocating a buffer. It wasn't always freeing that buffer on error.

SSH2 implementations which use DSA_do_verify() and ECDSA_do_verify() are given
the R and S values, and the data to be signed, by the client. Thus in order
to validate these signatures, SSH2 implementations will digest and sign
the data -- and then pass in properly provisioned DSA_SIG and ECDSA_SIG objects.
Unfortunately, the existing OpenSSL-1.1.0 APIs do not allow for directly setting
those R and S values in these objects, which makes using OpenSSL for such
SSH2 implementations much more difficult.
