- additional debug mess(age?) to learn 6K depth open req queue on cnbuild

r=alex
- delete_inode() for backfs inode should be called synchronous with smfs. To do this smfs_clear_inode_info() is called from smfs_delete_inode().

add types.h in Makefile.am for some tests build

 - the situation looks valid with opencache locks, but it floods consoles
   over. make it silent for a while

* don't touch base rpcpipe chain.
* invalidate svc gss cache item in case of init error.

 - additional assert

 - target_start_recovery_thread() starts a thread and must wait for
   completion because that thread sets recovering flag. but routine
   kernel_thread() returns pid > 0 in successful case, while the
   target_start_recover_thread() expects 0. so, first routine
   target_start_recovery_thread() returns immediately and chain
   mds_postsetup() -> mds_dt_connect() is called with obd_recovering==0.
   so, mds_postrecov_common() is called and it calls mds_cleanup_orphans()

 - use time_after_eq() instead of simple comparing

  fixes, need new nfsutils patches version 8.
* more precise error notify between kernel and lgssd.
* minor gss api param fix. and various minor gss fixes.

remove unsupported target on HEAD

remove SMFS options in autoMakefile.am because we should build smfs by default
on HEAD

1) remove unsupported target in lustre-core.m4 according to boc's suggest
2) add some args on 2.6-fc3 target

revert unapproved change (lustre-build HEAD is shared by all branches; the proper place for this change is in HEAD's .target.in files)

add kernel-2.6.10-2.6-fc3-i686-smp.config for lbuild on HEAD

change LINUX26 from 0 to 1 for HEAD in lbuild

some fix for fc3 lbuild on HEAD

  to catch and fix the problem

- checking for possible dentry mounting even if wait function returned failure - this helps to avpid post mounts.
- many changes in sanity-gns.sh

In smfs_helper, replace list_for_each_entry_safe with list_for_each_entry,
because we may unplugin the plg list

check out libsysio HEAD for all lustre builds

r=lee@sandia.gov

libsysio fixes which always apply the umask before calling liblustre.
With these changes, liblustre can stop worrying about the umask entirely.

which makes debugging at least theoretically possible.

  wasn't zeroing memory
- eliminate CDEBUG helper dupes; everything references CDEBUG now
- I wanted to keep obd_memory, portals_debug, et al in liblustre, but I can't
  have those bits compiled into userspace utils.  Hence the LUSTRE_UTILS
  preprocessor definition to distinguish them.
