Why is vmm.h needed?

Because w/o that compiling produces a lot errors:

$ cc vmopen.c
In file included from vmopen.c:3:
In file included from /usr/include/vmmapi.h:37:
/usr/include/machine/vmm_dev.h:61:13: error: use of undeclared identifier 'VM_MAX_SUFFIXLEN'
        char            name[VM_MAX_SUFFIXLEN + 1];
                             ^
/usr/include/machine/vmm_dev.h:80:18: error: field has incomplete type 'struct seg_desc'
        struct seg_desc desc;
 ...

I guess including "vmmapi.h" should self sufficient to be compiled.

I think we typically leave a blank line after this and before __END_DECLS in other headers.
