00ce01e52d cache-pool: Change segtype name from cache_pool to cache-pool 
Thin pools use "thin-pool" for the segment type name.  To be consistent,
we use "cache-pool" instead of "cache_pool".

d9bec60a23 cache/misc: Revert commit 94377dfd 
I am reverting the commit below - removing the new 'dm_config_get_int'
function and simply calling 'dm_config_get_uint32' while casting the
'int *' pointer parameter.

1ff7e214e0 cache: New 'cache' segment type 
This patch adds the cache segment type - the second of two necessary
to create cache logical volumes.  This segment type references the
cachepool (the small fast device) and the origin (the large slow device);
linking them to create the cache device.  The cache device is the
hierarchical device-mapper device that the user ulitmately makes use
of.

The cache segment sources the information necessary to construct the
device-mapper cache target from the origin and cachepool segments to
which it links.

90bbed3255 cache: New 'cachepool' segment type 
This patch adds the new cachepool segment type - the first of two
necessary to eventually create 'cache' logical volumes.  In addition
to the new segment type, updates to makefiles, configure files, the
lv_segment struct, and some necessary libdevmapper flags.

The cachepool is the LV and corresponding segment type that will hold
all information pertinent to the cache itself - it's size, cachemode,
cache policy, core arguments (like migration_threshold), etc.
