For $reason mobaxterm default on sending unusual sequence from home/del
key, which makes libedit unabel to catch them and bind them correctly.
mobaxterm seems popular on the windows environment, so add proper
keybinding to default shrc configuration so it works out of box.

In the recent history sh(1) has gain the missing features for it to
become a usable interractive shell:
- command completion
- persistent history support
- improvements on the default bindings in emacs mode
- improvements in the vi mode (repect $EDITOR)
- print a newline when exiting via ^D
- default prompt and improvements on how PS1 can be configured
- and more.
This changes also simplifies making tiny freebsd images with only sh(1)
as a shell
In the default configuration add 2 bindings which has been requested by
many during the HEADSUP discussion:
* csh like arrow history navigation
* ctrl-arrow to jump from word to words
Add an alias to make the history command exist as an alias to fc -l.
Patch the manpage to remove references to devq_openings and devq_queued.

The virtual LAPIC driver uses callouts to implement the LAPIC timer.
Callouts are armed using callout_reset_sbt(), which currently puts
everything on CPU 0. On systems running many bhyve VMs this results in
a large amount of contention for CPU 0's callout lock.
Modify vlapic to schedule callouts on the local CPU instead. This
allows timer interrupts to be scheduled more evenly among CPUs where
bhyve is running.

This makes the allocator simpler since it can assume object != NULL.
Also modify the function to unconditionally preserve PG_ZERO, so
VM_ALLOC_ZERO is effectively ignored (and still must be implemented by

This is the same as vm_page_alloc_noobj(), but allocates physically
contiguous runs of memory. For now it is implemented in terms of
vm_page_alloc_contig(), with the difference that
vm_page_alloc_noobj_contig() implements VM_ALLOC_ZERO by zeroing the
page.

Remove page zeroing code from consumers and stop specifying
VM_ALLOC_NOOBJ. In a few places, also convert an allocation loop to
simply use VM_ALLOC_WAITOK.
Similarly, convert vm_page_alloc_domain() callers.
Note that callers are now responsible for assigning the pindex.

The diff adds vm_page_alloc_noobj() and vm_page_alloc_noobj_domain().
These mostly correspond to vm_page_alloc() and vm_page_alloc_domain()
when no VM object is specified, with the exception that they handle
VM_ALLOC_ZERO by zeroing the page, rather than by preserving PG_ZERO.
This simplifies callers and will permit simplification of the
vm_page_alloc_domain() definition.
Since the new allocator variant is similar to vm_page_alloc_freelist(),
implement both of them using a common backend allocator function. No
functional change intended.

Without this patch, if a NFSv4.1/4.2 server replies NFSERR_DELAY to
a Close operation, the client loops retrying the Close while holding
a shared lock on the clientID. This shared lock blocks returns of
delegations, even though the server has issued a CB_RECALL to request
the delegation return.
This patch delays doing a retry of a Close that received a reply of
NFSERR_DELAY until after the shared lock on the clientID is released,
for NFSv4.1/4.2. To fix this for NFSv4.0 would be very difficult and
since the only known NFSv4 server to reply NFSERR_DELAY to Close only
does NFSv4.1/4.2, this fix is hoped to be sufficient.
This problem was detected during a recent IETF working group NFSv4
testing event.
