Update openssl to 3.0.5

[JonasVautherin]

• Fedora fails because it is missing perl dependencies
• Manylinux seems to fail for the same reason as Fedora (do we actually still need manylinux?)
• Ubuntu 20.04 fails with undefined reference to std::__throw_bad_array_new_length() (edit: that was due to the dependencies cache being shared with Ubuntu 22.04)
• SITL fails because it does not find our OpenSSL when building curl: Found OpenSSL: /usr/lib/x86_64-linux-gnu/libcrypto.so
• The musl builds fail because of this:

threads_pthread.c:(.text+0x228): undefined reference to `__atomic_is_lock_free'
/usr/xcc/armv7l-linux-musleabihf-cross/bin/../lib/gcc/armv7l-linux-musleabihf/11.2.1/../../../../armv7l-linux-musleabihf/bin/ld: threads_pthread.c:(.text+0x278): undefined reference to `__atomic_load_8'
collect2: error: ld returned 1 exit status

• iOS fails because of this (I asked about it here):

[ 75%] Performing build step for 'openssl'
ld: -bundle and -bitcode_bundle (Xcode setting ENABLE_BITCODE=YES) cannot be used together

Out of curiosity. Why? Or what's the difference from version 1.1 to 3?

[JonasVautherin]

I figured it may be worth trying, to get an idea. I can see potential issues that we may encounter:

• Ubuntu 22.04 comes with OpenSSL 3. Not sure if we can make a deb package without supporting OpenSSL 3 ourselves.
• At some point one of our dependencies depends on OpenSSL 3.
• What if somebody uses OpenSSL 3 and MAVSDK in their project, and MAVSDK builds against OpenSSL 1?

An open question is therefore whether we should support both OpenSSL 1 and OpenSSL 3, or if we could just move to OpenSSL 3, I guess? 🤔

[julianoes]

Do we have openssl 3 on Ubuntu 20.04?

[JonasVautherin]

No it's libssl1.1. But it seems like MAVSDK builds with both in many cases, so maybe we're lucky and it's fine to just update to 3 in our third parties and let the system take 1 when packaging?

[julianoes]

Having fun? 😂

[julianoes]

@JonasVautherin can we somehow go to XCode 14 where bitcode is apparently no longer a thing?

[JonasVautherin]

Let me have a look 👍

Merging with openssl for iOS still at 1.1.1.
