Move component_log_level out of struct into simple array

This will facilitate later things like per-client logging since
then a thread will just have a reference to the applicable
component_log_level array, and the macros will use the thread
local array instead of a global.

cache_inode_readdir: handle lookup failures on readdir callback

Add an option (retry_readdir) to either:
 - Keep going if a lookup fails, and return what we found (default)
 - Ask the client to retry (JUKEBOX (nfs3), DELAY (nfs4), EAGAIN (9P)) until
we get a clean result.

Changes related to delegations and delegation recalls.
  Delegate only if callback path is up.
  Do not recall if the path status is down, wait for next renew to tell
  the client about path state.
  Mark the path down if recall callback fails.
  renew will return NFS4ERR_CB_PATH_DOWN if the path state is down.
  callback path is established only during setclientid_confirm.
