Add in the tracing and this system call not implemented boilerplate. Do this by moving the guts of do_freebsd_syscall to freebsd_syscall. Put the tracing in the wrapper function. Since freebsd_syscall is a singleton static function, it will almost certainly be inlined. Fix comments that referred to do_syscall since that was renamed some tie ago.

2022-06-10bsd-user/freebsd/os-syscall.c: lock_iovecWarner Losh
lock_iovec will lock an I/O vec and the memory to which it refers and create a iovec in the host space that refers to it, with full error unwinding. 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.

2022-05-11Clean up ill-advised or unusual header guardsMarkus Armbruster
Leading underscores are ill-advised because such identifiers are reserved. Trailing underscores are merely ugly. Strip both. Our header guards commonly end in _H. 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.

2022-02-26bsd-user/freebsd/os-syscall.c: Move syscall processing hereWarner Losh
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.

FreeBSD has a MI ucontext structure that contains the MD mcontext machine state and other things that are machine independent. Create an include file for all the ucontext stuff. It needs to be included in the arch specific files after target_mcontext is defined.
