The noncontroversial portion of the last few days of changes:

- ENTRY/EXIT/RETURN cleanups
- extraneous header file removal
- made forgetting the 'setup' arguments in MDS/OST less fatal
- added the connection and token to the CONNECT RPC, so that we can do the
  pointer/token connection trick now
- fixed the 60 byte/-60 byte "leak"
- added ptlrpc and ldlm setup to llmount.sh, llrmount.sh, -client, and -server
