SQL Replay Recording

SUMMARY
-------------------------------------------------------
This extension enables recording sqlite API calls that access the database so that they can be replayed or examined.

USAGE
------------------------------------------------------
Recording is enabled by compiling sqlite with symbolic constant SQLITE_ENABLE_SQLRR defined.  
By default logs are written to /tmp/<databasename>_<pid>_<connection_number>.sqlrr, to choose another directory, set the environment variable SQLITE_REPLAY_RECORD_DIR to that path.
