This commit allow spa_load() to drop the spa_namespace_lock so that imports can happen concurrently. Prior to dropping the spa_namespace_lock, the import logic will set the spa_load_thread value to track the thread which is doing the import. Consumers of spa_lookup() retain the same behavior by blocking when either a thread is holding the spa_namespace_lock or the spa_load_thread value is set. This will ensure that critical concurrent operations cannot take place while a pool is being imported. The zpool command is also enhanced to provide multi-threaded support when invoking zpool import -a. Lastly, zinject provides a mechanism to insert artificial delays when importing a pool and new zfs tests are added to verify parallel import functionality.
