Several changes in dmsetup and libdevmapper:
...
- add DM_UDEV_DISABLE_LIBRARY_FALLBACK udev flag to rely on udev only
- export dm_udev_create_cookie function to create new cookies on demand
- add --udevcookie, udevcreatecookie and udevreleasecookie for dmsetup
(to support "udev transactions" where one cookie value can be used for
several dmsetup calls)
- don't use DM_UDEV_DISABLE_CHECKING env. var. anymore and set the state
automatically (based on udev and libdevmapper dev path comparison)

Cleanup gcc warning: cast discards qualifiers from pointer target type
...
API of the library should remain the same as the 'const' is not
mangled into the function name in C.

Add support to disable udev checking: DM_UDEV_DISABLE_CHECKING=1 env. variable.
...
Sometimes it is really needed to switch off udev checking and the warnings we show when
we detect that udev has not done its job right - the messages like "Udev should have done
this and that. Falling back to direct node creation/removal. " etc.
This would be especially handy while setting DM_DEV_DIR env var that could be set to a
different location than standard /dev (udev can't create nodes/symlinks out of that one
directory that is configured into udevd). The exact same situation happens while we're
running our tests.

Support udev flags even when udev_sync is disabled or not compiled in.
...
This provides better support for environments where udev rules are installed
but udev_sync is not compiled in (however, using udev_sync is highly
recommended). It also provides consistent and expected functionality even
when '--noudevsync' option is used.
There is still requirement for kernel >= 2.6.31 for the flags to work though
(it uses DM cookies to pass the flags into the kernel and set them in udev
event environment that we can read in udev rules).

Several changes to udev support code:
...
- we have these levels when the udev rules are processed:
10-dm.rules --> [11-dm-<subsystem>.rules] --> [12-dm-permissions.rules] -->
13-dm-disk.rules --> [...all the other foreign rules...] --> 95-dm-notify.rules
- each level can be disabled now by
DM_UDEV_DISABLE_{DM, SUBSYSTEM, DISK, OTHER}_RULES_FLAG
- add DM_UDEV_DISABLE_DM_RULES_FLAG to disable 10-dm.rules
- add DM_UDEV_DISABLE_OTHER_RULES_FLAG to disable all the other (non-dm) rules.
We cutoff these rules by using the 'last_rule', so this one should really be
used with great care and in well-founded situations. We use this for lvm's
hidden and layer devices now.
- add a parameter for add_dev_node, rm_dev_node and rename_dev_node so it's
possible to switch on/off udev checks
- use DM_UDEV_DISABLE_DM_RULES_FLAG and DM_UDEV_DISABLE_SUBSYSTEM_RULES_FLAG
if there's no cookie set and we have resume, remove and rename ioctl.
This could happen when someone uses the libdevmapper that is compiled with
udev_sync but the software does not make use of it. This way we can switch
off the rules and fallback to libdevmapper node creation so there's no
udev/libdevmapper race.

Change exit() to _exit() in the child process. exit flushes stdio file buffers,
...
_exit doesn't. If there were some open files, an error in exec and subsequent
exit() would cause the buffers to be flushed twice.
Example:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
int main()
{
printf("buu");
if (!fork()) {
execl("/bin/true-not-exists", "/bin/true", NULL);
exit(1);
}
wait(NULL);
return 0;
}
