This reverts commit da16cc77.

Re-adding it as a form of merging to master.

The behavior of the unittest module was changed in the face of a
test exiting, so we need to use os._exit() instead of sys.exit()
to terminate.

manually reviewed
also used my check-changelog script.

Merged jreed-host branch. See trac #872. This includes code updates, new manual page, but no unit tests.

Don't document b10-host in README, since now have manual page.

Document existing b10-host command.

Regenerate the roff file.

thought with review comment.  update the code comment accordingly.
in fact overflow could (probably) happen if the caller of toWire() tries to
render to many RRsets with an invalidly large buffer size limit.  also,
the risk of overflow is not specific to this case; it can happen after
inserting ordinary RRs.  So if we want to care about such cases we should
rather cover all of them than making a TSIG specifici check.  For now,
I don't bother to check such stupid attempt of the caller.  It would simply
result in bogus wire data and wouldn't make a program crash or something.

It is not a complete compatible replacement for host,
so use a different name. (I brought this up at least a year ago.)

this fixes regression for MacOS X.

This is not completed, but add to source tree anyways.

to LDFLAGS.

according to the libtool manual,
http://www.gnu.org/software/libtool/manual/html_node/Link-mode.html
the intent seems to propagate -R from a library's dependency_libs to
the program that uses the library.  On our systems libtool doesn't do
this propagation and we needed the global rpath, but if the documentation
is correct, there may be a version of libtool that works.

rpath in the global LDFLAGS.
also remove BOTAN_RPATH from libcryptolink/Makefile.am (which is not part
of fix, but is simply unnecessary)

Add missing libdns++ rdata files for the distribution (this
fixes distcheck error). Change three generated libdns++
headers to "nodist" so they aren't included in the distribution
(they were mistakenly included in last tarball).

This fixes two immediate problems:

If you do a distcheck build or create a tarball it would mistakenly
include the rdataclass.h, rrclass.h, and rrtype.h headers.
They are supposed to be generated at build time.

Also the rp_17 rdata files were not included in the distribution,
so building would fail because rdataclass didn't define the RP class.

This update also includes the nsec_bitmap rdata files. (I didn't
see any problem related to this, but I assume they were meant to
be shipped.)

I added two generated files to BUILT_SOURCES. Not necessarily
required, but this implies that the target for these should be
done before the regular build (so this makes sure the generated
files are created).

Discussed a little on jabber on Friday.

This should fix the existing distcheck autobuilder failures.

I alphabetically sorted some EXTRA_DIST entries so I can quickly
see differences when updating this.  This is only for what is
included in the tarball.

Other fixes:
 - cppcheck filter adjustment
 - (indirect) dependency on libbotan.  actually we should be able to make
   the link within libcryptolink, so I chose that approach.  hopefully
   it doesn't break autobuild.

they were actually not "SOURCES", and caused distcheck failures.
