If you are using the FTP daemon, please consider using the port ftp/tnftpd
which is the same FTP server, but newer and might have more/better
functionality.
This results in us providing only one ftp daemon by default.

Right now libteken processes TF_REVERSE internally and returns the
toggled colors to the console driver. This isn't entirely correct. This
means that the bold flag is always processed by the foreground color,
while reversing should be done after the foreground color has been set
to a brighter version by the bold flag.
This is no problem with the syscons driver, because with VGA it only
supports 16 foreground and 8 background colors. My WIP console driver
reconfigures the graphics hardware to disable the blink functionality
and uses 16 foreground and 16 background colors. This means that this
driver will handle the TF_REVERSE flag a little different from what
syscons does right now.

This change can be easilly MFCed to STABLE_8 at the appropriate moment.

I initially committed libteken to sys/dev/syscons/teken, but now that
I'm working on a console driver myself, I noticed this was not a good
decision. Move it to sys/teken to make it easier for other drivers to
use a terminal emulator.
Also list teken.c in sys/conf/files, instead of listing it in all the
files.arch files separately.
In the lockmgr support:
- GIANT_RESTORE() is just called when the sleep finishes, so the current
code can ends up into a giant unlock problem. Fix it by appropriately
call GIANT_RESTORE() when needed. Note that this is not exactly ideal
because for any interation of the adaptive spinning we drop and restore
Giant, but the overhead should be not a factor.
- In the lock held in exclusive mode case, after the adaptive spinning is
brought to completition, we should just retry to acquire the lock
instead to fallthrough. Fix that.
- Fix a style nit
In the sx support:
- Call GIANT_SAVE() before than looping. This saves some overhead because
in the current code GIANT_SAVE() is called several times.

based Intel Macs. Since r189055, these platforms started freezing when
ACPI is being initialized for unknown reason. For these platforms, we just
use the old PAT layout. Note this change is not enough to boot fully on
these platforms because of other problems but it makes debugging possible.
Note MacBook5,2 may be affected as well but it was not added here because
of lack of hardware to test.
- Initialize PAT MSR fully instead of reading and modifying it for safety.

Note that this changes error reporting behaviour somewhat - before,
no error was reported if ACL couldn't be copied because the target
filesystem doesn't support ACLs. Now, it will be reported - of course,
only if there actually is an ACL to copy.

L2 code does not have the ethernet address for the destination
within the broadcast domain in the table, we remember the
original mbuf in `la_hold' in arpresolve() and send out a
different packet with an arp request.
In case there will be more upper layer packets to send we will
free an earlier one held in `la_hold' and queue the new one.
Once we get a packet in, with which we can perfect our arp table
entry we send out the original 'on hold' packet, should there
be any.
Rather than continuing to process the packet that we received,
we returned without freeing the packet that came in, which
basically means that we leaked an mbuf for every arp request
we sent.
Rather than freeing the received packet and returning, continue
to process the incoming arp packet as well.
This should (a) improve some setups, also proxy-arp, in case it was an
incoming arp request and (b) resembles the behaviour FreeBSD had
from day 1, which alignes with RFC826 "Packet reception" (merge case).
Rename 'm0' to 'hold' to make the code more understandable as
well as diffable to earlier versions more easily.
Handle the link-layer entry 'la' lock comepletely in the block
where needed and release it as early as possible, rather than
holding it longer, down to the end of the function.

Remove the altkstacks, instead instantiate threads with kernel stack
allocated with the right size from the start. For the thread that has
kernel stack cached, verify that requested stack size is equial to the
actual, and reallocate the stack if sizes differ [1].
This fixes the bug introduced by r173361 that was committed several days
after r173004 and consisted of kthread_add(9) ignoring the non-default
kernel stack size.
Also, r173361 removed the caching of the kernel stacks for a non-first
thread in the process. Introduce separate kernel stack cache that keeps
some limited amount of preallocated kernel stacks to lower the latency
of thread allocation. Add vm_lowmem handler to prune the cache on
low memory condition. This way, system with reasonable amount of the
threads get lower latency of thread creation, while still not exhausting
significant portion of KVA for unused kstacks.
