or --license as most apps would do, instead it waits for data to
compress on stdin. Because of that, if `bzip2 --version' is called,
bogus `bzip2: I won't write compressed data to a terminal' error
message will be displayed, and checking for bzip2 version in scripts
as in
bzip2 --version 2>&1 | grep -o "Version [^,]*"
will hand as bzip2 would wait for data to compress on stdin. Fix
this by exiting right after showing version/license text.
I've tried to push this upstream for more than a year, but author
is unresponsive, so upstream may be considered dead.
Ubuntu applies similar fix, for the note.

The ipfw tables lookup code caches the result of the last query. The
kernel may process multiple packets concurrently, performing several
concurrent table lookups. Due to an insufficient locking, a cached
result can become corrupted that could cause some addresses to be
incorrectly matched against a lookup table.

BZ_NO_COMPRESS support to the bzip2 sources directly (yes, this takes file
off the vendor branch, but looks like bzip2 maintainer doesn't care), so that
it will not be removed when the next upgrade is performed. Also, add a short
note on how to test bzip2 support.
