cttctx locking options for record read

In V10.3 and later, the cttctx test program supports locking options for record reads. This test program adds a record, reads it with a write lock, and deletes it. It can be run in a mode that only reads the records. Prior to this revision, the test program always acquired a write lock when reading the record.

This revision adds an option to perform the reads with no lock, with a read lock, or with a write lock. The following command line options are available:

• -or - Read records with no lock.
• -orl - Read with a read lock.
• -orL - Read with a write lock (this was the behavior prior to this update).

When these options are used, the test program displays the type of locking that is used:

• Read with no lock
• Read with read lock
• Read with write lock
