Issues building on OpenBSD

[brad0]

I am trying to build the SDK on OpenBSD but have run into a few issues building.

include/mega/posix/megafs.h requires adding OpenBSD to where FreeBSD is.

src/http.cpp OpenBSD does not have AI_V4MAPPED. I had a patch of..

+#ifdef __OpenBSD__
+        hints.ai_flags = AI_ADDRCONFIG;
+#else
         hints.ai_flags = AI_V4MAPPED | AI_ADDRCONFIG;
+#endif

But you might want to handle it in a different manner.

src/posix/fs.cpp:1813:50: error: no member named 'f_type' in 'statfs'
    LOG_info << "Filesystem type: " << statfsbuf.f_type;
                                       ~~~~~~~~~ ^

OpenBSD does not have a f_type field. FreeBSD and macOS do.

OpenBSD does have f_fstypename like macOS.

From sys/mount.h...

ping.

I noticed the src/posix/fs.cpp issue has been resolved with the relevant code being ifdef __liniux__'d.

I created a PR #2650 to take care of the rest.
