Server backend storage hang should not cause the mount point to hang.

Submitted-by: Krishna Srinivas 
NOTE: fixed compilation issues in posix.c introduced while merging

storage/posix polls for FS/kernel being functional by issuing
statvfs() call. In case statvfs expires the timer, storage/posix will
send CHILD_DOWN to upper translator. Ultimately this will cause
protocol/server to disconnect all clients connected and also cleans up
the data structures. Hence if soft lockup or other kernel bug causes
backend FS to hang, the clients will not be hung.

protocol/server: deep resolution support

2009-10-23T14:03:23+00:00

when requested ino/gen is not available in the inode table cache,
then use the path presented by the client to lookup entries with
the hope that the requested ino/gen gets populated into the cache.

re-perform regular search after finishing the deep component
lookup

server-helpers: cleanup connection only if there are no active transports.

2009-06-08T13:47:40+00:00

- thanks to Ioannis Aslanidis  for reporting.
  - breakup the server_connection_cleanup into smaller procedures.
  - do following operations in a single atomic operation.
      1. conn->active_transports--
      2. collecting pointer to lock table and all fds if there are no active transports
    this will avoid any race conditions.
