Commit 519129f added support to multi-thread 'zpool import' for the case where block devices are scanned for under /dev/. This commit generalizes that logic and applies it to the case where device names are acquired from libblkid. The zpool_find_import_scan() and zpool_find_import_blkid() functions create an AVL tree containing each device name. Each entry in this tree is dispatched to a taskq where the function zpool_open_func() validates the device by opening it and reading the label. This may result in additional entries being added to the tree and those device paths being verified. This is largely how the upstream OpenZFS code behaves but due to significant differences the non-Linux code has been dropped for readability. Additionally, this code makes use of taskqs and kmutexs which are normally not available to the command line tools. Special care has been taken to allow their use in the import functions.
