[PATCH v2 0/5] parallels: Add duplication check, repair at open, fix bugs

[Alexander Ivanov <alexander.ivanov@virtuozzo.com>]

Fix incorrect data end calculation in parallels_open().

Split image leak handling to separate check and fix helpers.

Add checking and repairing duplicate offsets in BAT

Replace fprintf() by qemu_log().

Image repairing in parallels_open().

v2:
2: Moved outsude parallels_check_leak() 2 helpers:
   parallels_get_leak_size() and parallels_fix_leak().
   
3: Used highest_offset() helper in parallels_check_leak(). Fixed a typo.
   Added comments. Replaced g_malloc() call by qemu_memalign(). Replaced
   bdrv_pread() call by bdrv_co_pread(). Got rid of keeping bytes and
   sectors in the same variable. Added setting the bitmap of the used
   clusters for a new allocated cluster if it isn't out of the bitmap.
   Moved the leak fix to the end of all the checks. Removed a dependence
   on image format for the duplicate check.
   
4 (old): Merged this patch to the previous.
4 (former 5): Fixed formatting.
5 (former 6): Fixed comments. Added O_INACTIVE check in the condition.
              Replaced inuse detection by header_unclean checking.
              Replaced playing with corutines by bdrv_check() usage.
