- Add and use mapping of fcntl(2) commands to new BSM constant space.
- Adopt (int) rather than (long) arguments to a number of auditon(2)
commands, as has happened in Solaris, and add compatibility code to
handle the old comments.
Note that BSM_PF_IEEE80211 is partially but not fully removed, as the
userspace OpenBSM 1.1alpha5 code still depends on it. Once userspace
is updated, I'll GCC the kernel constant.

runtime with 'sysctl net.inet.flowtable.enable=1'.
- Embedded users can remove it entirely from the kernel by adding 'nooption FLOWTABLE' to
their kernel config files.
- A minimal hookup will be added to ip_output in a subsequent commit. I would like to see
more review before bringing in changes that require more churn.

uses PMAP functions to scan and iterate over memory
chunks, as well as handle memory mappings used during
dumping.
the PMAP layer can choose to return physical memory
chunks or virtual memory chunks. For minidumps, the
chunks should be virtual.
The default MMU I/F implementation for the scan_md()
method returns NULL. Thus, when a PMAP implementation
does not implement the required methods, an empty
core file is created. Here, empty means having an ELF
header only.

- Create a partitions file to linprocfs to make Linux fdisk see

When copying big structures, LLVM generates calls to memmove(), because
it may not be able to figure out whether structures overlap. This caused
linker errors to occur. memmove() is now implemented using bcopy().
Ideally it would be the other way around, but that can be solved in the
future. On ARM we don't do add anything, because it already has
memmove().
