[irods/irods_tests#2] Update tests to avert broken pipes
[#1822] update tests
[#1959] added irods, slink, z3950
[#1981] removed unused database resource code from ilsresc
[#1912] remove existing misleading setup and upgrade scripts

These files are no longer correct.

The preferred way to install iRODS is with a binary installation via
package manager.  If this is not possible, there will be a documented
build-in-place option available.
[#1962] remove existing legacy copyright files
[#1984] restructure installation to remove rodsBoot user

This required triggering on whether the rodsBoot user exists.

If the rodsBoot account exists during installation, this is the
first run of irods_setup.pl:
 - Setup the database and admin account
 - Bounce the server, come up in admin account
 - Delete the rodsBoot user

Otherwise, if the rodsBoot account does not exist, this is not
the first run of irods_setup.pl:
 - Bounce the server, come up in admin account
 - Run largely redundant setup

This keeps rodsBoot from being an extra account lying around on
production installations.

This also allows re-installation of a package atop an existing
working iCAT without error.
