Update OpenSSL to version 1.0.2g

[mrezai]

Update to latest stable version. All Makefile files, Perl files(.pl), Assembly files(.s, *.S) and test files(test) removed.
Please see #4275 last comment for more information.

Thanks a lot! I checked the patch locally and it builds and seems to run fine. I also compared the files to those of the upstream 1.0.2g (mostly to check for potential forgotten or leftover files, etc.).

I found some diffs which I remember from earlier "bugfix" commits, so thumbs up for keep their changes. I think most of them are due to us not defining OPENSSL_SYS_WIN32 for Windows builds, that's probably something to look into so that we can drop our patches. (All diffs renamed to .txt as GH won't access .diff files)

• dtls1.h: dtls1.h.diff.txt
• md5.h: md5.h.diff.txt
• o_str.c: o_str.c.diff.txt
• rand.h: rand.h.diff.txt
• opensslconf.h: opensslconf.h.diff.txt

opensslconf.h is likely what we need to work on if we want to drop our patches.

I'll check for potential obsolete files/missing files and merge.

Files that we have and that are not in the upstream tarball:

$ for file in $(cat files_list.txt); do   filename=$(basename $file); matches=$(find /home/akien/tmp/openssl/openssl-1.0.2g/ -type f -name $filename); if [ -z "$matches" ]; then echo "No match for $file"; fi; done
No match for builtin_openssl2/nocpuid.c
No match for builtin_openssl2/SCsub
No match for builtin_openssl2/crypto/des/t/test

All good.

Code files (.c and .h) that the upstream tarballs has and our repo doesn't:

$ for file in $(find /home/akien/tmp/openssl/openssl-1.0.2g -type f -name "*.c" -o -name "*.h"); do   filename=$(basename $file); matches=$(find builtin_openssl2/ -type f -name $filename); if [ -z "$matches" ]; then echo "No match for $file" >> nomatch.txt; fi; done

This gives some output due to the other folders in the upstream tarball (apps, demos, engines, etc.), and some .*test.c files in crypto and ssl, but after filtering these out it's all good. So once again nice job @mrezai :D
