Galen Charlton bc87274c66 bug 6281: introduce LC::CallNumber::LC for sorting LC call numbers
This replaces the previous hand-coded normalizer.  Because
LC::CallNumber::LC appears to reject strings that aren't valid
LC call numbers, significant changes to the test cases were
made as well -- however, the one that really counts is the
last one which verifies the sorting.

To recalculate the call number sort key for each item, it is necessary
to run misc/maintenance/touch_all_items.pl

To test, create item records with the following call numbers, setting
the classification sort to 'lcc':

QC100 .U57 NO. 555 1986
QC145 .A57 V.12 1980
QC145.45 .H4 D65 1998
QC995 .E29 1997

Next, make a report of them in the inventory tool.  The items should be sorted
in the above order.
