shmif: export LOCK_* definitions
They will be used by upcoming shmif_pcapin.

Add shmif_pcapin(1) utility program

It can send any frames that are stored in a pcap(3) file format to
shmif(4) Ethernet interface via the bus of it.  If you want to write
some tests for networking with rump kernels and the tests need to send
frames that are difficult to generate by stock programs, shmif_pcapin
can be helpful.

The author of shmif_pcapin is k-goda@IIJ and the man page is written
by ozaki-r.

tests: add a basic test for shmif_pcapin

The original author of the test is k-goda@IIJ.  ozaki-r tweaked
the test to improve stability and added comments.
distrib, etc: install shmif_pcapin and its tests

Move the lockops together with the interface -- they are needed
only at runtime.

Include a timestamp in the frame header.  When converting to pcap,
it can give some idea of when packets were sent.

nb. it's the sending host's timestamp, not an observer timestamp
like in the typical pcap case.

Include a pointer to the beginning of the buffer and add support
to the packet dumper.  This helps in situations where the juicy
details are in a bus multiple generations old.

* include a magic number in the bus format
* simplify offset calculations by making them start from beginning of data

Make shmif memory access slightly more sane.  Create a header which
is shared by the interface and the bus analyzer.
