Merged to the master branch.

I have added a new --split=<list> command line option to the lsmem.

It allows to control the way how lsmem merges memory blocks to the
ranges. The default is to use differences in STATE,REMOVABLE,NODE and
ZONES attributes. The ranges are no more affected by --output, it
means commands like

    lsmem --output=RANGE
    lsmem --output=RANGE,ZONES

returns the same memory ranges. You have to use --split to define your
policy:

    lsmem --split=REMOVABLE,STATE

will create the ranges according to REMOVABLE and STATE attributes.
