Add corporate author (110) to TPAC author pool

As requested in LP#1168186, here is a simple attempt to add corporate
authors to the author 'pool' in TPAC.

We may also want to consider adding 111 (meeting or conference as
main entry), but that isn't totally clear cut.

LP1168186 - Add tag 111 and remove subfield 4 from author pool

Add meeting/conference main entry (111) to TPAC author pool.

Remove subfield 4 from the author data because the information contained
refers to relator and may not be helpful at this time.

Add libmar to build update tools to the repo.

This adds code from Mozilla to build a command line mar program and the
libmar library that it uses.  This code is now dual-licensed under the
MPL 2.0 and GPL v2 or later.

We also add our own version of mbsdiff using a modified version of Colin
Percival's FreeBSD-licensed bsdiff program.  We also copy the crc32 code
from Mozilla's updater.

Add libmar as "subpackage" in cofigure.ac.

Add AC_CONFIG_SUBDIRS macro call for Open-ILS/xul/staff_client/external/
libmar so that our update tools will get configured and built when
Evergreen is built.

Modify make_updates.sh for our update tools.

Instead of downloading mar and mbsdiff from Mozilla.org's servers,
we check if they exist in Open-ILS/xul/staff_client/external/libmar/tool
and if not we build them.  They should be there already.

Fix segmentation fault in mbsdiff and fix crc by linking with libbz2.

Doh! I typed memcpy when I really wanted memset.

This does not actually introduce any new dependencies.  Evergreen
updates/installation already requires bzip2.  If bzip2 is present,
then libbz2 is present.  We don't need libbz2 headers, just the
library itself for a single data structure used in crc32 calculation.

Add new dependency on libbz2-dev(el).

Our own mar tools add a build dependency on libbz2.  The easiest way to
make sure this is there seems to be to install libbz2-dev(el).

Also, update the release notes to reflect the new dependency.

Change autoconf required version for libmar's configure.ac

Having it set to 2.68 (current for Ubuntu Precise) broke autoreconf for other
distributions. Notably Debian Squeeze/Wheezy have 2.67 and Ubuntu Lucid has
2.65 for their autoconf version.

Set a minimum requirement of 2.61 that we use in the existing options.
