Transactions no longer take root dir, no longer lock & block: commit can fail spuriously with EAGAIN, not ETIMEDOUT. Speeds up transactions by over 1000 times, should be NFS safe. New program: xs_tdb_dump to dump raw TDB contents. Don't do failure testing: we are no longer robust against all ENOMEM 8( Introduce "struct node" which contains perms, children and data. Make struct xs_permissions unpadded, so we can write to tdb w/o valgrind complaints. Gently modify TDB to use talloc, not do alloc on tdb_delete. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
