Add update code - make setup-ds.pl -u do updates

Updates are implemented in:
perl - code that plugs in to setup - scriptlets that are imported into
the setup perl interpreter and executed in process, giving access to all
of the packages and context provided by setup
ldif - applied to instances, in the same manner as ConfigFile directives
to setup
other - any executable file, shell script, etc. can be invoked, with a limited
amount of context from the setup process
An update directory is added to the package - /usr/share/dirsrv/update - this
directory contains the update files - the update filenames begin with two digits
and are executed in numeric order (00 first, then 01, etc. up to 99) which
should provide enough flexibility
In addition, there are 5 stages of update:
pre - invoked before any instance specific code
preinst, runinst, postinst - invoked for each instance
post - invoked after any instance specific code
Example files are provided which demonstrate how to get the context.
There are two different modes of operation for update:
online - must supply a bind dn and password for each instance - servers must
be up and running
offline - operates directly on the dse.ldif - servers must be shutdown first
A new section is added to the .inf file that can be passed in

[slapd-instancename]
RootDN = binddn
RootDNPwd = bindpw

The RootDN is optional - if not supplied, it will get the nsslapd-rootdn attribute from the dse.ldif for the instance.
I also fixed some problems with error messages.
The pam pta plugin entry was giving object class violations, so I added the
missing attributes - note that these are replaced by the plugin code when
the plugin is loaded - they are only needed during setup.

Fixed usage of $_ - $_ behaves like a dynamically scoped variable - which
means if you use it in an outer context, you cannot use it in an inner
context, even if it is used in a different function.  Rather than attempting
to figure out how to use $_ safely in lower level functions, I just removed
the use of it altogether, which also makes the code easier to read.
