+initialize msghdr in a compatible manner
+
+msghdr stuct from socket.h is not same between musl and glibc
+where musl claims to be more posix  compliant where as glibc seems
+to fill whats needed for linux sizewise and chooses long enough types
+which maybe questionable, therefore constructing a structure with explicit
+constructor is not going to work correctly for musl and glibc at same time
+
+see
+https://git.musl-libc.org/cgit/musl/commit/arch/x86_64/bits/socket.h?id=7168790763cdeb794df52be6e3b39fbb021c5a64
+
+This fix initialized the struct to 0 first and then sets the struct elements
+by name, so we dont have to hard code the positions of elements when initializing
+structure
