[Kir Kolyshkin]

OpenVZ project has released a new ploop version. Read below for
more information. Everybody is advised to upgrade.


Changes
=======
(since 1.6)

New functionality:
* Large ploop image format support
   - Now image size limit is 64 TB (was 2TB)
   - Kernel >= 042stab078 is required
* Move ploop_grow* functions from tools to lib
* ploop grow: add DiskDescriptor.xml support
* ploop init, ploop_create_image(): add FS blocksize parameter

Improvements:
* make_fs(): create ext4fs with lazy_itable_init
   - 3x smaller size and 3x faster creation time for 20GB image
* lib/ploop.h: "unexport" some internal functions
* Use /proc/self/mountinfo to get mount point by device
* More clear errors on parsing DiskDescriptor.xml
* print_output(): generalize print_lsof(), improve
* add_delta(): print more diags if EBUSY
* extend_delta_array(): print errors, return SYSEXIT_*
* run_prg(): print error if execvp() failed
* lib/balloon.c: print file name in an error message
* Introduce and use p_memalign(), fix errno handling
* Improvements and fixes to ploop_grow_*() to be used from library
* ploop_read_disk_descr(): set *di to NULL in case of error
* ploop_find_dev(): always assume ploop cookie is supported
* resize_fs(): try harder to find resize2fs binary
* Makefile.inc: ability to add CFLAGS

Fixes:
* lib/lock.c: create_file(): make sure dir exists (#2493, #2597)
* lib/fsutils.c: use ploop_execvp, drop absolute paths to binaries (#2595)
* ploop_log(): fix loglevel checking for file logging
* ploop_snapshot_switch_param: guids are const
* Recreate ploopXpY devices on ploop mount
* ploop_find_dev(): treat ENODEV as ENOENT on /sys reads
* use basename() to strip device from path
* ploop list: check for extra arguments
* ploop balloon: fix -f option processing
* Fixed lots of memory leaks, mostly on error paths
* open_delta(): simplify error handling
* Fixes for other issues big and small, reported by Coverity
