The standard syscall() function or macro uses the libc return value convention. Errors returned from the kernel as negative values are stored in errno and -1 is returned. Users who want to avoid using errno don't have a way to call raw syscalls and check the returned error. Add a new macro _syscall() which works like the standard syscall() but passes through the return value from the kernel unchanged. The naming scheme and return values match the named _sys_foo() system call wrappers already part of nolibc.
