debug.ddb_use_printf sysctl, output kernel debugger data to both the
console and kernel message buffer via printf. This fixes the case where
backtrace() went directly to the console and should help debugging greatly.
Thanks to Ian Dowse for the work, minor edits or any bugs are by myself.

return an error value that made Write_Disk() abort. While on the
subject, improve the initialization of the error variable in read_gpt()
and update_gpt() even though nothing was broken there.
and NgAllocRecvData(), that dynamically allocate buffer for a binary
message, an ascii message, and a data packet, respectively. The size
of the allocated buffer is equal to the socket's receive buffer size
to guarantee that a message or a data packet is not truncated.
- Get rid of the static size buffer in NgSendAsciiMsg().

the proc lock only if we actually need to perform a stop. This
avoids two locks and unlocks of the process lock each system call,
and wins me about 20% on a simply system call test (getuid(),
which would otherwise require no locking). This also has a net
improvement of about 10MB/s on some of the SMP bandwidth tests
I'm running.

- malloc() returns a void* and does not need a cast
- when called with M_WAITOK, malloc() can not return NULL so don't
check for that case. The result of the check was bogus anyway since
it would leave the interface broken.
re-breaks non-interactive portupgrade (or at least old versions of
portupgrade); I'll see if I can put together a solution which avoids
breaking anything later.

assure backward compatibility (conditional on !BURN_BRIDGES), look it up
by its old name first, and log a warning (but accept the setting) if it
was found. If both the old and new name are defined, the new name takes
precedence.
Also export vm.kmem_size as a read-only sysctl variable; I find it hard to
tune a parameter when I don't know its default value, especially when that
default value is computed at boot time.
kbd_attach() is called kbd[0-9]+, with a different unit number. This
makes it impossible to write a devd rule which will automatically
switch to a USB keyboard when one is attached, because there is no way
to guess the correct device node to pass to kbdcontrol.
Therefore, change kbd_attach() to create a device node using the
keyboard device's real name (atkbd0, ukbd0...), and create the
kbd[0-9]+ node as an alias for backward compatibility.
loading on a particular version of Windows. For example, a .INF file
for a Windows 2000 driver may have an empty [foo.NT.5.1] section which
will be ingored on Win2K (whose .INF parser won't look for sections
decorated with .NT.5.1) in favor of a [foo] section. Likewise, a
WinXP file will have an empty [foo] section which will be ignored in
favor of [foo.NT.5.1].
The problem is, we can handle both Win2K and WinXP drivers, and we
don't want to exclude either one.
As a workaround, we try to pretend we are WinXP by default and search
for sections decorated with .NT.5.1, but if we don't turn up any records,
we assume that maybe we're being fooled by a sabotaged .INF file and
make one more pass looking for undecorated sections instead.
This allows us to parse the .INF files for both the Win2K and the WinXP
Centrino wireless drivers.
I'd give anything for 5 minutes alone in a room with whoever wrote
Microsoft's .INF file parser. Just 5 minutes. That's all.
on an SIOCSIFADDR (by way of brain damage in net80211).
Also, avoid trying to set NDIS_80211_AUTHMODE_AUTO since the Microsoft
documentation I have recommends not using it, and the Centrino driver
seems to dislike being told to use it.
every system call, and that grabs and release the process lock each
time. Don't fix it (yet), but document it so we know to fix it.
Also should be a 5.3-RELEASE todo item.
