tunable allowing automatic parsing of VPD data to be disabled. The
default is left as-is; if you are having problems with hard hangs at boot
due to VPD, try setting hw.pci.enable_vpd=0. A proper architectural
solution has been under discussion for some time, but this allows me to
boot my test machines in the mean time.

variable to avoid invalid constraints in dead code. Use an array of
u_char's (inside a struct) instead of a char/short/int/long variable so
that the variable and its accesses can be spelled in the same way in all
cases and code doesn't need to be cloned just to hold the spelling
differences.
Fixed strict-aliasing errors in PCPU_SET() and in the amd64 PCPU_GET().
Cast to (void *) as in rev.1.37 of the i386 version where the errors
were fixed for the i386 PCPU_GET() only. It would be more correct to
copy to and from the temp. variable using memcpy(), but then an
ifdef tangle would be required to ensure using the builtin memcpy().
We depend on fairly aggressive optimization to put the temp. variable
only in a register despite it being copied using
*(type *)(void *)&anothertype and could depend on this when using
memcpy() too. This seems to work right even for -O0, but the -O0 case
has not been completely tested.
This change gives identical object code for all object files in LINT
on amd64 (except for one file with a __TIME__ stamp). For LINT on
i386 it gives unimportant differences in instruction order and padding
in a few object files. This was only tested for -O.
This change (actually a previous version of it) gives the following
reductions in the number of object files in LINT that fail to compile
with -O2 but without the -fno-strict-aliasing kludge:
- amd64: 29 (down from 211)
- i386: 36 (down from 47)
gcc-3.4.6 actually allows the invalid constraints that result from not
using the temp. variable, at least with -O[1-2], but gcc-3.3.3 crashes
on them and I don't want to depend on compiler bugs.

LABEL_TO_SLOT() macro used by policy modules to query and set label data
in struct label. Instead of using a union, store an intptr_t, simplifying
the API.
Update policies: in most cases this required only small tweaks to current
wrapper macros. In two cases, a single wrapper macros had to be split into
separate get and set macros.
Move struct label definition from _label.h to mac_internal.h and remove
_label.h. With this change, policies may now treat struct label * as
opaque, allowing us to change the layout of struct label without breaking
the policy module ABI. For example, we could make the maximum number of
policies with labels modifiable at boot-time rather than just at
compile-time.

Don't perform a nested include of _label.h in mac.h, as mac.h now
describes only the user API to MAC, and _label.h defines the in-kernel
representation of MAC labels.
Remove mac.h includes from policies and MAC framework components that do
not use userspace MAC API definitions.
