Do not expose low_water_mark in mda yet, if it has no use.
We do not allow to be set via current lvm tool code.
Usage needs to be clarified first.

DM_THIN_MAX_DATA_BLOCK_SIZE to make it more obvious, for which
this define is useful in thin API.

Message support for thin provisiong
...
lvm part of messaging.
Each message is now stored it's own thin pool section:
message1 {
create = lv
}
Messages are queued to thin pool dm target when this target
is going to be resumed or used through some dependency.
Currently 'delete' message are purely queued and processed
with next thin pool resume operation (i.e. create_thin).
WARNING - thin provisioning support is developmental code.

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.
