Without this, if script_name_sep was not set in the rc.conf files,
local scripts will not be executed on startup or shutdown.

o) Since we unwrap the sendfile syscall, check the return value of
writev(2) to see if it didn't complete all the data.
Previously if only a partial writev() succeeded, it would proceed
to sendfile(2) even though the headers weren't completely sent.
o) Properly adjust the "bytes to send" to take into account sendfile(2)'s
behaviour of counting the headers against the bytes to be transfered
from the file.
o) Correct the problem where EAGAIN was being returned from _sys_sendfile(2)
however the wrapper didn't update the 'sent bytes' parameter to take into
account for it. This is because sendfile can return EAGAIN even though
it has actually transfered data.
Special thanks to Justin Erenkrantz <jerenkrantz@apache.org> for bringing
this to my attention and giving an excellent way to reproduce the problem.

where our security related sysctl tuneables are located. Also, this
will help if/when we move _security node out from under _kern as to help
make _kern less cluttered.

- The MI portions of struct globaldata have been consolidated into a MI
struct pcpu. The MD per-CPU data are specified via a macro defined in
machine/pcpu.h. A macro was chosen over a struct mdpcpu so that the
interface would be cleaner (PCPU_GET(my_md_field) vs.
PCPU_GET(md.md_my_md_field)).
- All references to globaldata are changed to pcpu instead. In a UP kernel,
this data was stored as global variables which is where the original name
came from. In an SMP world this data is per-CPU and ideally private to each
CPU outside of the context of debuggers. This also included combining
machine/globaldata.h and machine/globals.h into machine/pcpu.h.
- The pointer to the thread using the FPU on i386 was renamed from
npxthread to fpcurthread to be identical with other architectures.
- Make the show pcpu ddb command MI with a MD callout to display MD
fields.
- The globaldata_register() function was renamed to pcpu_init() and now
init's MI fields of a struct pcpu in addition to registering it with
the internal array and list.
- A pcpu_destroy() function was added to remove a struct pcpu from the
internal array and list.
Tested on: alpha, i386
