Add helper_iovec_unlock to unlock the partially locked iovec in case there's an error. The code will be used in iovec_unlock when that is committed. Note: memory handling likely could be rewritten to use q_autofree. That will be explored in the future since what we have now works well enough.

Normalize the exceptions. Macros should be ALL_CAPS. Normalize the exception. Done with scripts/clean-header-guards.pl. include/hw/xen/interface/ and tools/virtiofsd/ left alone, because these were imported from Xen and libfuse respectively.

| | | | | | | | | | | | | | | | While there is some commonality between *BSD syscall processing, there's a number of differences and the system call numbers and ABIs have been independent since the late 90s. Move FreeBSD's proessing here and delete it. The upstream implementation is somewhat different than the current implementation. It will be much easier to upstream these from scratch, justifying the final result, rather than working out the diffs and justifying the changes. Also tweak a comment to qemu standard form.
