7f815706ca Fix lv_info open_count test
When verify_udev_operations was disable, code for stacking fs operation for
lvm links was completely disable - but this code was also used for collecting
information, that a new node is being created.

Add a new flag which is set when a creation of lv symlinks is requested which
should restore old behaviour of lv_info function, that has called fs_sync()
before quere for open count on device.

56cab8cc03 Synchronize with udev for lv_info
In case the open_count is requested via lv_info - check if there
are any udev operations in-progress - and wait for them
before checking for lv_info

937a21f0d2 Speedup consequent activation calls
Stop calling fs_unlock() from lv_de/activate().
Start using internal lvm fs cookie for dm_tree.
Stop directly calling dm_udev_wait() and
dm_tree_set/get_cookie() from activate code -
it's now called through fs_unlock() function.

Add lvm_do_fs_unlock()

Call fs_unlock() when unlocking vg where implicit unlock solves the
problem also for cluster - thus no extra command for clustering
environment is required - only lvm_do_fs_unlock() function is added
to call lvm's fs_unlock() while holding lvm_lock mutex in clvmd.

Add fs_unlock() also to set_lv() so the command waits until devices
are ready for regular open (i.e. wiping its begining).

Move fs_unlock() prototype to activation.h to keep fs.h private
in lib/activate dir and not expose other functions from this header.

f6fdfd56e4 Add internal fs cookie
Add functions for handling internal lvm cookie used for
all dm_tree operations until fs_unlock is called.

cda69e17ef Add activation/udev_rules config option in lvm.conf.
Add dm_tree_add_dev_with_udev_flags to provide wider support for udev flags.

8ef2b021ed Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

de6c918392 o Removed old files
o  rewrote activate.c to use dev-manager, I'm sure these two will merge
   at some point.

o  Rename is broken ATM

o  dev-manager puts the calls through to fs.c for layers that have the
   'visible' flag set.

6d52fb460b o Split activate.c into a high level (remaining in activate.c) and low level (ll-activate.[hc]) API.
o  Creation of a device from an lv now lives in activate-lv.c

4a624ca055 o ACTIVE is no longer a status flag - lv_active() used to check if an LV
is active in the device-mapper.
o Many operations can be carried out regardless of whether the VG is
  active or not.
o vgscan does not activate anything - use vgchange.
o Change lvrename to support renaming of active LVs.
o Remove '//' appearing in some pathnames.
o Dummy lv_check_segments() for compilation.
