Run timers in workqueue

Timers (such as nd6_timer) typically free/destroy some data in callout
(softint). If we apply psz/psref for such data, we cannot do free/destroy
process in there because synchronization of psz/psref cannot be used in
softint. So run timer callbacks in workqueue works (normal LWP context).

Doing workqueue_enqueue a work twice (i.e., call workqueue_enqueue before
a previous task is scheduled) isn't allowed. For nd6_timer and
rt_timer_timer, this doesn't happen because callout_reset is called only
from workqueue's work. OTOH, ip{,6}flow_slowtimo's callout can be called
before its work starts and completes because the callout is periodically
called regardless of completion of the work. To avoid such a situation,
add a flag for each protocol; the flag is set true when a work is
enqueued and set false after the work finished. workqueue_enqueue is
called only if the flag is false.

Proposed on tech-net and tech-kern.

Check for duplicate module names before loading modules that were
"pushed" by the boot loader.  The boot loader pushes the module
name for the root file system (unless the root file system is ffs)
even if the file system module is built into the kernel.  When
this happens, we get a lot of "redefined symbol" error messages.
This fix does not alter the behavior of pushing the file system
name.  It simply avoids the redefined symbol errors by detecting
that the module is already built-in to the kernel and not trying
to load another copy.
While here, differentiate the error message text between "failed
to load" and "failed to fetch_info" conditions.

(maxv)

When a user pmap is created, it is populated with the higher kernel
slots, which become accessible upon kernel entry (syscall, cpu switch,
or whatever). Put the NOX bit in the user recursive slot, so the whole
tree does not appear as executable in kernel mode.

This is already what is done in the kernel pmap.

(maxv)

KNF this function a little

(maxv)

When loading a module from VFS and from the bootloader, the kernel packs
up the module segments into one big RWX chunk. Split this chunk into two
different text and data+bss+rodata chunks. The latter is made non-
executable. This also provides some kind of ASLR, since the chunks are
not necessarily contiguous.

(maxv)

The CPU considers a given va as executable if none of its levels have
the NOX bit. With the top level recursive slot, however, several levels
are recursively omitted, which implies that each entry that is not the
child of NOX-ed parents actually appears somewhere in the virtual space
as executable via this slot, even if it is followed by an underlying
entry that has the NOX bit.

This recursive slot is only used to edit the page tree itself. Make it
non-executable.
