Remove LibC.

This was the interface between Perl and C introduced in 36a5349b but since f0ef73db has only been used by the Perl integration tests.  This is expensive code to maintain just for testing.

The main dependency was the interface to storage, no matter where it was located, e.g. S3.  Replace this with the new-introduced repo commands (d3c83453) that allow access to repo storage via the command line.

The other dependency was on various cfgOption* functions and CFGOPT_ constants that were convenient but not necessary.  Replace these with hard-coded strings in most places and create new constants for commonly used values.

Remove all auto-generated Perl code.  This means that the error list will no longer be maintained automatically so copy used errors to Common::Exception.pm.  This file will need to be maintained manually going forward but there is not likely to be much churn as the Perl integration tests are being retired.

Update test.pl and related code to remove LibC builds.

Ding, dong, LibC is dead.
