3ffe9aa27d Mangle device name on dm_task_set_name/newname call if necessary.
If dm_task_set_name/newname is called, the name provided will be
automatically translated to correct encoded form with the hex enconding
so any character not on udev whitelist will be mangled with \xNN
format where NN is hex value of the character used.

By default, the name mangling mode used is the one set during
configure with the '--with-default-name-mangling' option.

c239c824f5 Add internal expected_errno dm_tast var
Certain errno codes could be expected in some situations thus
add experimental support for them.

When expected errno is set after ioctl error - function skips error
printing and exits succefully.

Currently only useful for thin pool messages.

6b1629455a Add dm_task_retry_remove fn to use retry logic for device removal.
This call ensures that the dm device removal is retried several
times before failing.

bd7f41d83c Remove support for the original dm ioctl interface version 1.
Leave the basic support for multiple versions in case we have a new version
in future.

84f191ce5a Add --addnodeonresume, --addnodeoncreate
Add new function dm_task_set_add_node() to select between 2 types
of node creation in device directory.

DM_ADD_NODE_ON_RESUME is now default and ensures node is created on
resume. Old original behavior is accessible with DM_ADD_NODE_ON_CREATE.
In this case node would be created during dmsetup create --notable.

For the user 2 new options for dmsetup create are added:
[{--addnodeonresume | --addnodeoncreate }]

Properly working node creation on resume is needed for proper operation
stacking and ability to correctly check in which state the device should
after whole udev transation.

21ed352ac5 Add support for querying a device's inactive table.
Currently this data is invisible to userspace.
Requires dm >= 4.16 (likely to be in linux 2.6.33).

f7c1e5f60d Fix backward compatibility for major:minor query.
Is an application uses query and set major:minor
to device, it should not fallback to default major by default.

Add new function whoich allows that (and use it in lvm2).
