avoid the problem of holding a non-sleep lock during a page fault as
reported by witness. It also uses atomics where possible to avoid having
to acquire the exclusive lock. In addition, it consistently uses
memset()/memcpy() instead of bzero()/bcopy().

bcopy() is required (i.e. overlapping copy).

imgp->interpreted to a bitmask instead of, functionally, a bool. Each
imgactivator now requires its own flag in interpreted to indicate whether
or not it has already examined argv[0].
Change imgp->interpreted to an unsigned char to add one extra bit for
future use.
With this change, one can execute a shell script from a 64bit host native
make and still get the binmisc image activator to fire for the script
interpreter. Prior to this, execution would fail.

execution to a emumation program via parsing of ELF header information.
With this kernel module and userland tool, poudriere is able to build
ports packages via the QEMU userland tools (or another emulator program)
in a different architecture chroot, e.g. TARGET=mips TARGET_ARCH=mips
I'm not connecting this to GENERIC for obvious reasons, but this should
allow the kernel module to be built by default and enable the building
of the userland tool (which automatically loads the kernel module).
