	fix for lockdep warning. adds separate lockdep subclass for mdd_orphan
dir locking.

take current service time into account, not only using
the timeout gotten by ldlm_get_enqueue_timeout

With AT enabled, the recovery window can be excessively long (6000+
seconds). To address this problem, we no longer use
OBD_RECOVERY_FACTOR when extending the recovery window (the connect
timeout no longer depends on the service time, it is set to
INITIAL_CONNECT_TIMEOUT now) and clients report the old service
time via pb_service_time.

Third of three patches for the root squash feature

map root UID/GID to UID/GID set via configuration parameter root_squash

Second of three patches for the root squash feature

This patch is to allow configuration parameters to contain spaces
It is accopmpished with
1. in mgs_write_log_params (renamed to mgs_write_log_param)
    assume the incoming string is a single parameter (the while loop is removed)
2. in mgs_write_log_target, call mgs_write_log_params for each parameter
a) new funcion class_get_next_param copies the entire next parameter into a temp buffer
   spaces are included if they are inside quotes (single or double)
   the first space outside of quotes is the terminator
   the quotes are stripped in the copy
   the copy is null-terminated
b) repeatedly call class_get_next_param and mgs_write_log_param in a loop from mgs_write_log_target

First of three patches for the root squash feature

This adds three functions to manipulate with lists of NID ranges:
cfs_parse_nidlist - parses nid range list and
                    creates structure of lists of [lo,hi,stride,net]
                    which can be used to check matching a NID to set of NIDs
cfs_free_nidlist - frees structures allocated on nidlist parsing
cfs_match_nid - check whether a NID matches to set of NIDs
cfs_iswhite - auxiliary function to check if a character is a whitespace

These functions have prefixes cfs_ instead of libcfs_ because of bug #17167.

Example of NID range list: 10.2.0.[1-20/2]@tcp [0,2,6]@elan0 [1,2,4-100/4]@elan1
nidlist syntax:
  <nidlist>         :== <nidrange> [ ' ' <nidrange> ]
  <nidrange>        :== <addrrange> '@' <net>
  <addrrange>       :== '*' |
                        <ipaddr_range> |
                        <numaddr_range>
  <ipaddr_range>    :== <numaddr_range>.<numaddr_range>.<numaddr_range>.<numaddr_range>
  <numaddr_range>   :== <number> |
                        <expr_list>
  <expr_list>       :== '[' <range_expr> [ ',' <range_expr>] ']'
  <range_expr>      :== <number> |
                        <number> '-' <number> |
                        <number> '-' <number> '/' <number>
  <net>             :== <netname> | <netname><number>
