7cd8194c99 Use readahead of underlying device and not default (smaller) one. 
When we are stacking LV over device, which has for some reason
increased read_ahead (e.g. MD RAID), the read_ahead hint
for libdevmapper is wrong (it is zero).

If the calculated read_ahead hint is zero, patch uses read_ahead of underlying device
(if first segment is PV) when setting DM_READ_AHEAD_MINIMUM_FLAG.

Because we are using dev-cache, it also store this value to cache for future use
(if several LVs are over one PV, BLKRAGET is called only once for underlying device.)

This should fix all the reamining problems with readahead mismatch reported
for DM over MD configurations (and similar cases).

bb6db55686 Use suspend with flush when device size was changed during table preload. 
This allows online mirror resize, also removes condition to preventing
code to do this.

7f4173ab22 Fail add tree node when requested major/minor is used. 
Check for major/minor collision is added in _add_dev_to_dtree()
where we already read info by uuid,
so in the case of requesting major/minor it queries device-mapper
by major/minor for device availability.
