In two places where the assertions would be meaningful, convert them to

Linux' XArray allows to store a NULL pointer as a value. `xa_load()`
would return NULL for both an unused index and an index set to NULL. But
it impacts `xa_alloc()` which needs to find the next available index.
However, our implementation relies on a radix tree (see `linux_radix.c`)
which does not accept NULL pointers as values. I'm not sure if this is a
limitation or a feature, so to work around this, a NULL value is
replaced by `NULL_VALUE`, an unlikely address, when we pass it to
linux_radix.

The 0b70e3e78b changed the original design of a single entry point
into pfil(9) chains providing separate functions for the filtering
points that always provide mbufs and know the direction of a flow.
The motivation was to reduce branching. The logical continuation
would be to do the same for the filtering points that always provide
a memory pointer and retire the single entry point.
o Hooks now provide two functions: one for mbufs and optional for
memory pointers.
o pfil_hook_args() has a new member and pfil_add_hook() has a
requirement to zero out uninitialized data. Bump PFIL_VERSION.
o As it was before, a hook function for a memory pointer may realloc
into an mbuf. Such mbuf would be returned via a pointer that must
be provided in argument.
o The only hook that supports memory pointers is ipfw:default-link.
It is rewritten to provide two functions.
o All remaining uses of pfil_run_hooks() are converted to
pfil_mem_in().
o Transparent union of pfil_packet_t and tricks to fix pointer
alignment are retired. Internal pfil_realloc() reduces down to
m_devget() and thus is retired, too.

Powerpc compilers often define _BIG_ENDIAN or _LITTLE_ENDIAN depending
on the byte order of the target. This interfers with the endian.h and
sys/endian.h APIs which expect those two to be 4321 or 1234.
Unconditionally undefine these two before we define them to work around
this issue. By including endian.h, the programmer is saying they want
this API not the native one. This matches historic practice as well.

Very old versions of gcc defined _BIG_ENDIAN and _LITTLE_ENDIAN. So to
work around that, we undefined them here. However, that causes problems
for programs that do:

result of weirdly nested includes in the ports world that are hard to
unwind, drop this workaround to help more ports build out of the box.
If there's still an issue here (and my testing hasn't shown it), we'll
fix the issue in a brand-new way once I have a reproducer.
