Replace manual dm ioctls with libdm.

This mostly 1:1 replaces manual ioctls to device-mapper with calls to
libdm. There were two exceptions:

(1) There is a very old table-load-retry loop to workaround issues with
    umount (b/7220345). This loop has been preserved, however, it now
    includes DM_DEV_CREATE as well as DM_TABLE_LOAD.
(2) There was some ancient code to set DM_DEV_GEOMETRY for obb
    dm-devices. This never did anything since geometry must be set after
    loading a table. When setting it before (as vold was doing), the
    subsequent DM_TABLE_LOAD will clear it.
