9ac61d2ba2 lvcreate parsing for thin provisioning.

e59e2f7c3c Move the core of the lib/config/config.c functionality into libdevmapper,
leaving behind the LVM-specific parts of the code (convenience wrappers that
handle `struct device` and `struct cmd_context`, basically). A number of
functions have been renamed (in addition to getting a dm_ prefix) -- namely,
all of the config interface now has a dm_config_ prefix.

cf98c05082 Add detect_internal_vg_cache_corruption to lvm.conf
Add config option to enable crc checking of VG structures.
Currently it's disabled by default.

For the internal test-suite this check it is enabled.

Note: In the case the internal error is detected, debug build with
compile option DEBUG_ENFORCE_POOL_LOCKING helps to catch the source
of the problem.

cac52ca4ce Add basic RAID segment type(s) support.
Implementation described in doc/lvm2-raid.txt.

Basic support includes:
- ability to create RAID 1/4/5/6 arrays
- ability to delete RAID arrays
- ability to display RAID arrays
Notable missing features (not included in this patch):
- ability to clean-up/repair failures
- ability to convert RAID segment types
- ability to monitor RAID segment types

afc8a3b104 Fix create_temp_name to replace any '/' found in the hostname with '?'.
There's a possibility someone will use the '/' in the hostname. Since we
generate a temporary file name (path) including the hostname, any '/' would
be ambiguous.

We can always set such hostname using 'sethostname' from unistd.h. But the
'hostname' command already includes the check and removes the '/' char.
However, some old versions still allow that.
See: https://bugzilla.redhat.com/show_bug.cgi?id=711445.

Since this is only a temporary name and the possibility of this error is
quite negligible, we don't need any complex escape sequence here, just a
simple char replace.

edcda01a1e Obtain device list from udev by default if LVM2 is compiled with udev support.
Also, add a new 'obtain_device_list_from_udev' setting to lvm.conf with which
we can turn this feature on or off if needed.

If set, the cache of block device nodes with all associated symlinks
will be constructed out of the existing udev database content.
This avoids using and opening any inapplicable non-block devices or
subdirectories found in the device directory. This setting is applied
to udev-managed device directory only, other directories will be scanned
fully. LVM2 needs to be compiled with udev support for this setting to
take effect. N.B. Any device node or symlink not managed by udev in
udev directory will be ignored with this setting on.

794e94fe16 Replace PV_MIN_SIZE with function pv_min_size()
Add configurable option to define minimal size of
of block device usable as a PV.

pv_min_size() is added to lvm-globals and it's being
initialized through _process_config.

Macro PV_MIN_SIZE is unused and removed.

New define DEFAULT_PV_MIN_SIZE_KB is added to lvm-global
and unlike PV_MIN_SIZE it uses KB units.

Should help users with various slow devices attached to the system,
which cannot be easily filtered out (like FDD on /dev/sdX):

7c9fd3ea84 Don't use floor() in _bitset_with_random_bits
Use _even_rand() function instead of floor() in _bitset_with_random_bits().
floor() function is missing in dietlibc (on architectures other than x86).
Moreover using floor() to clip rand results does not assure even result
distribution. _even_rand() uses integer arithmetic only and is designed to
return evenly distributed results.

We can already detect MD devices internally. But when using MD partitions,
these have "block extended major" (blkext) assigned (259). Blkext major
is also used in general, so we need to check whether the original device
is an MD device actually.

6ddb5ecd72 Set appropriate udev flags for reserved LVs.
There's no need for foreign udev rules to touch LVM reserved devices
(snapshot, pvmove, _mlog, _mimage, _vorigin) even if they happen to
be visible. The same applies for /dev/disk content - no need to create
any content for these devices (and so no need to run any "blkid" etc.).
This also prevents setting any inotify "watch" from udev rules on such
devices that is a source of race conditions (the rules need to honor
DM_UDEV_DISABLE_OTHER_RULES_FLAG for this to work though).

bda3982016 Use UUIDs instead of names while processing event handlers.
Internally, we used DM names instead of UUIDs while processing event
handlers. This caused problems while trying to vgrename a VG with active LVs
where the names are being changed and so the devices were not found then.
The patch also contains a little bit of refactoring, moving "build_dlid" code
found in dev_manager.c to "build_dm_uuid", now in lvm-string.c (so we have
build_dm_uuid and build_dm_name at one place).

7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'
