to intptr_t. This fixes a compiler warning (integer from pointer
without cast) in scvgarndr.c when SC_PIXEL_MODE is defined.
o Define readb() and writeb(). Both are used in scvgarndr.c when,
guess what, SC_PIXEL_MODE is defined.
Both changes are ia64 specific.

reacquire the "first" object's lock while a backing object's lock is held.
Since this is a lock-order reversal, vm_fault() uses trylock to acquire
the first object's lock, skipping the sequential access optimization in
the unlikely event that the trylock fails.
in struct vm_page are defined as u_int for 16K pages and u_long
for 32K pages, with the implied assumption that long will at least
be 64 bits wide on platforms where we support 32K pages.
from the ia32 specific stuff. Some of this still needs to move to the MI
freebsd32 area, and some needs to move to the MD area. This is still
work-in-progress.
the default label support in /etc/mac.conf. Rather than maintain
each default label type in an explicit global variable in mac.c,
keep a list of defaults loaded from the configuration file.
Generalize the parsing so that we support both the older:
default_file_labels foo
default_ifnet_labels foo
default_process_labels foo
And also a new:
default_labels file foo
default_labels ifnet foo
default_labels process foo
We now accept arbitrary object classes in the first argument. If
the same object is specified more than once, we discard the
earlier definition in favor of the later one.
Add a new API, mac_prepare_type(), which accepts a mac_t to
prepare, as well as an object name in the second argument, which
will pull a default label set for the object out of the
configuration loaded by mac_init_internal(). This permits the libc
to adapt to new objects known about by applications but not by libc
at compile-time.
Also liberalize the error handling a bit: if we're using implicit
initialization (i.e., the application didn't explicitly initialize
the MAC code), ignore syntax errors and only use valid lines. In
the future, we may want to add explicit warnings and do this a
bit more consistently.
While here, add support for a MAC_CONFFILE environmental variable,
which may be used to specify an alternative mac.conf configuration
file if the application isn't running with modified privilege
(issetugid()).
