942d6ef29f Add support for new IMPORT{db} udev rule. 
This rule appeared in udev v152 and it helps us to support spurious events
where we didn't have any flags set (events originated in udevadm trigger
or the watch rule). These flags are important to direct the rule application.
Now, with the help of this rule, we can regenerate old udev db content.
To implement this correctly, we need to flag all proper DM udev events with
DM_UDEV_PRIMARY_SOURCE_FLAG. That happens automatically for all ioctls
generating events originated in libdevmapper.

91345610f8 Strictly require libudev if udev_sync is used. 
This prevents some confusion when libudev was not found so udev_sync was disabled
automatically. Configure was successful though giving only a tiny warning.

Also, if "dmsetup udevcreatecookie" is used, never return 0x000000 as a result if
udev is not running and keep the output blank.

ac3691f70e Add support for ioctl's DM_UEVENT_GENERATED_FLAG. 
We need to know whether we should wait for any uevent or not when
using udev_sync. A kernel patch was posted recently that changed the
way uevents are sent on dm device resume - it is sent only if the
device has been suspended before. There's also a new DM_UEVENT_GENERATED_FLAG
in the ioctl to notify userspace whether the event was generated.

If the uevent was not generated (e.g. the situation where the device is
*not* suspended and we call a resume), we just call dm_udev_complete
explicitly from within libdevmapper itself to prevent infinite waiting
while trying to synchronise with udev processing.

f0e073fcdc 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)

d2b43c4b34 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.

0d408f0c43 Disable udev rules on change event with DISK_RO=1. 
There's a new change udev event generated since kernel 2.6.32 that
notifies userspace about a change in read-only attribute for block
devices (with DISK_RO=1 environment variable set).

We need to detect this and disable the rule application so the
meaning of this change event is not interchanged with the regular
change event used while resuming/renaming DM devices.

If there's anybody awaiting this notification in foreign rules,
he can still check for this env var and do the appropriate actions
separately.

584d1fb7d1 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).

'last_rule' option has been removed from udev (version >= 147).

From now on, we require foreign rules to check and honor
ENV{DM_UDEV_DISABLE_OTHER_RULES_FLAG} instead. Foreign
rules should be skipped totally when this flag is set.

 - add multipath DM_ACTION=="PATH_FAILED" filter
 - remove unnecessary filters in the headers of the rules (we can simply use DM_UDEV_RULES_VSN instead)
 - fix symlink priorities in /dev/disk/ (snapshot volumes have low priority for FS UUID symlinks so it will not overwrite symlinks for the origin)

The device-mapper mirror CTR table has been changing over time.  This has

'block_on_errors' and 'cluster' features.  (The code that does this was
accidentally committed in the previous check-in.  This check-in finishes

12ca060e9f Support crypt segment in libdevmapper tree. 
- it can support multiple segments, but note that
to work properly, correct IV (initialization vector)
offset parameter must be set properly.

Because most usage of IV start offset is when we join
several crypto segments together (so iv_offset is the segment
start offset), DM_CRYPT_IV_DEFAULT is defined to simplify
the process.

Function accepts the string in cipher agrument (already
including chainmode and iv type; chainmode and iv parameters are NULL
in this case) or user can provide split parameters which will
join into dm-crypt cipher specification "cipher-chainmode-iv".

All these parameters must be supplied in correct dm-crypt format.

1f1aaf43ea Add an "all" field which expands to all fields of the report type. 
For example in LVM2, "pv_all" gives all PV fields.
"seg_all" gives all LV segment fields.

"all" gives all fields of the final report type.  I think this is more
useful than just adding the current prefix.

So "lvs -o seg_all" gives all the LV segment fields, whilst
"lvs --segments -o all" adds in LV and VG fields too.

"lvs -o all -O vg_name" has report type LVS+VGS so includes all LV and all
VG fields.

Checks added for DM device names to allow only names < DM_NAME_LEN,
otherwise a part of lengthy name would be silently ignored and could
cause confusion while using dmsetup. Also, the name should not contain
'/' character, if it is used in context of creating a new device
or renaming the existing one (because we do not consider full path
to devices, they do not exist in filesystem yet) and appropriate error
messages are shown.

detect failure even if it's hidden behind ferror.  [Using dm_fclose's
extra ferror test here is probably not needed, since the amount written
is nowhere near BUFSIZ, but use it regardless, for consistency. ]
