[lwip-devel] [task #14247] socket API: implement recvmsg msg_control support

[Joel Cunningham]

Follow-up Comment #26, task #14247 (project lwip):

Simon,

Thanks for clarifying the error.  I'm also fine with the added void *.  RFC
says the type should be unsigned char *, but void should be fine since we are
always casting to the real type (for CMSG_DATA)

I've also pushed a fix for ALIGN_H and ALIGN_D to address the potential
problem on 16-bit arches where MEM_ALIGN is 2, but we need to be aligning to
4.  This change also ensures that there is no unaligned access even for
systems that support it (x86)
