$hline argument for setting the --hline parameter value. This change does
not effect any current modules as it turns out that not one single usage of
f_dialog_msgbox() relied on accepting more than a first argument (read: all
occurrences quoted the first parameter; so $* was never depended upon).
This will allow some custom invocations of --msgbox to roll over to this
function (for example, in `mouse/disable').

performance.
- Always free to the alloc bucket if there is space. This gives LIFO
allocation order to improve hot-cache performance. This also allows
for zones with a single bucket per-cpu rather than a pair if the entire
working set fits in one bucket.
- Enable per-cpu caches of buckets. To prevent recursive bucket
allocation one bucket zone still has per-cpu caches disabled.
- Pick the initial bucket size based on a table driven maximum size
per-bucket rather than the number of items per-page. This gives
more sane initial sizes.
- Only grow the bucket size when we face contention on the zone lock, this
causes bucket sizes to grow more slowly.
- Adjust the number of items per-bucket to account for the header space.
This packs the buckets more efficiently per-page while making them
not quite powers of two.
- Eliminate the per-zone free bucket list. Always return buckets back
to the bucket zone. This ensures that as zones grow into larger
bucket sizes they eventually discard the smaller sizes. It persists
fewer buckets in the system. The locking is slightly trickier.
- Only switch buckets in zalloc, not zfree, this eliminates pathological
cases where we ping-pong between two buckets.
- Ensure that the thread that fills a new bucket gets to allocate from
it to give a better upper bound on allocation time.

optionally start the traversal from a previously found element by passing the
element in as "var". Passing a NULL "var" retains the same semantics as the
regular FOREACH macros.
Kudos to phk for suggesting the "FROM" suffix instead of my original proposal.

This is actually a fully functional build except:
* All internal shared libraries are static linked to make sure there
is no interference with ports (and to reduce build time).
* It does not have the python/perl/etc plugin or API support.
* By default, it installs as "svnlite" rather than "svn".
* If WITH_SVN added in make.conf, you get "svn".
* If WITHOUT_SVNLITE is in make.conf, this is completely disabled.
To be absolutely clear, this is not intended for any use other than
checking out freebsd source and committing, like we once did with cvs.
It should be usable for small scale local repositories that don't
need the python/perl plugin architecture.

removing the {curlies} around ntpdate_config (they are unnecessary).

This checks that every node that has children specifies their register sizes.
This is not enabled by default, as the default sizes are sometimes required
(including by some DTS in the tree), but can help when writing new device
trees so that you can check that you actually meant the defaults.
This is a workaround, as for unknown yet reason the keys binded on the Partition Edition window are the one from partlist instead of the one from standard "formfield"

star for me. EVENTHANDLER_DEREGISTER() attempts to acquire the lock which is
held by the event handler framework while executing event handler functions,
leading to deadlock.
Move EVENTHANDLER_DEREGISTER() to alq_load_handler() and thus deregister the ALQ
shutdown_pre_sync handler at module unload time, which takes care of the
originally reported panic and fixes the deadlock introduced in r250951.

needed for the last 10 years. Far too much of the internal API is
exposed, and every small adjustment causes applications to stop working.
To kick this off, bump the API version to 0x17 as should have been done
with r246713, but add shims to compensate. Thanks to the shims, there
should be no visible change in application behavior.
I have plans to do a significant overhaul of the API to harnen it for
the future, but until then, I welcome others to add shims for older
versions of the API.

- Convert the regular keg based allocator to use the new import/release
functions.
- Move some stats to be atomics since they would require excessive zone
locking/unlocking with the new import/release paradigm. Make
zone_free_item simpler now that callers can manage more stats.
- Check for these cache-only zones in the public APIs and debugging
code by checking zone_first_keg() against NULL.
