libopenbsd is an internal library which
to bring in compatibility stuff from OpenBSD.
This will allow us to bring in more
OpenBSD utilities into the FreeBSD base system.
We similarly use libnetbsd for bringing in stuff from NetBSD.

to transmit the buffer.
ath_tx_start() may manipulate/reallocate the mbuf as part of the DMA
code, so we can't expect the mbuf can be returned back to the caller.
Now, the net80211 ifnet work changed the semantics slightly so
if an error is returned here, the mbuf/reference is freed by the
caller (here, it's net80211.)
So, once we reach ath_tx_start(), we never return failure. If we fail
then we still return OK and we free the mbuf/noderef ourselves, and
we increment OERRORS.

This will enable the elimination of a workaround in the USB driver that
artifically allocates buffers twice as big as they need to be (which
actually saves memory for very small buffers on the buggy platforms).
When deciding how to allocate a dma buffer, armv4, armv6, mips, and
x86/iommu all correctly check for the tag alignment <= maxsize as enabling
simple uma/malloc based allocation. Powerpc, sparc64, x86/bounce, and
arm64/bounce were all checking for alignment < maxsize; on those platforms
when alignment was equal to the max size it would fall back to page-based
allocators even for very small buffers.
This change makes all platforms use the <= check. It should be noted that
on all platforms other than arm[v6] and mips, this check is relying on
undocumented behavior in malloc(9) that if you allocate a block of a given
size it will be aligned to the next larger power-of-2 boundary. There is
nothing in the malloc(9) man page that makes that explicit promise (but the
busdma code has been relying on this behavior all along so I guess it works).
Arm and mips code uses the allocator in kern/subr_busdma_buffalloc.c, which
does explicitly implement this promise about size and alignment. Other
platforms probably should switch to the aligned allocator.
In retrospect, having an alias for UTF-8 does not bring any real benefits
and it can cause confusion. Let's remove this *.UTF8 locale symlinks
which is closer to the convention of the other BSDs.
GCC testsuite is also removing utf8 and UTF8 locales for portability
with BSD.

In the old days, device drivers passed NULL for the parent tag when creating
a new tag, and on arm platforms that resulted in a global tag representing
overall platform constraints being substituted in the busdma code. Now all
drivers use bus_get_dma_tag() and if there is a need to represent overall
platform constraints they will be inherited from a tag supplied by nexus or
some bus driver in the hierarchy.
The only arm platforms still relying on the old global-tag scheme were some
xscale boards with special PCI-bus constraints. This change provides those
constraints through a tag supplied by the xscale PCI bus driver, and
eliminates the few remaining references to the old global var.

Previous code supported only "continuous" code without any kind of
branch instructions. To change that, new function was implemented
which parses current instruction and returns an addres where
the jump might happen (alternative addr).
mdthread structure was extended to support two breakpoints
(one directly below current instruction and the second placed
at the alternative location).
One of them must trigger regardless the instruction has or has not been
executed due to condition field.
Upon cleanup, both software breakpoints are removed.
This implementation parses only the most common instructions
that are present in the code (like 99.99% of all), but there
is a chance there are some left, not covered by the parsing routine.
Parsing is done only for 32-bit instruction, no Thumb nor Thumb-2
support is provided.
