OS Support

[supernomad]

quantum needs to support more operating systems than just linux. However it is highly unlikely that quantum will ever support multiple architectures, and will continue to just focus on amd64/x86_64.

Current target OS's are:

• FreeBSD
• OpenBSD
• Darwin
• Solaris (Only If Possible)
• Windows (Only If Possible)

Did some quick testing to see just how much work would be required to get BSD based systems working and it is unfortunately a lot of work. A few key things will need to be updated and changed:

• The netlink library needs to be wrapped and capable of being changed based on the OS, as the current netlink library vishvananda/netlink only supports linux which was expected.
• The device module will need to be reworked to support different IOCTL formats and constants.
• The socket module will need to be reworked to support different syscall constants.
• The DTLS library in the crypto module needs to be reworked to support different LDFLAGS for the various OSes.
• The Makefile needs to be reworked to be fully POSIX compliant.

Thankfully openssl compiles just fine, which would have been a deal breaker if it didn't. This was expected but at the same time is a relief to know for sure.
