- cleanups in cmobd and others:

- cleanups in cmobd and others:
  - change LUSTRE_MDC_NAME (and others) to form like OBD_MDC_DEVICENAME to be coherent with
    OBD_LMV_DEVICENAME and others. Because some OBDs used one form and others used another one.

  - removed different guesses of OBD types from name of some functions in cmobd. Say
    cmobd_find_master() now is called cmobd_find_obd() as all it does is finds obd
    by uuid and may be used not only for finding master. Also cmobd_lmv_obd() is renamed to
    cmobd_md_obd() etc. Improved function (a bit smaller of code) wich looks for master.

- in memory leaks detector do not remove memory track in case of freeing memory chunk different
  of size. marking it instead as such to show in final log of leaks with special hint.

- fixes in lconf. COBD and CMOBD should use LMV and LOV devices with diffrent names to avoid
  issues in the case when both they run on the same node (like in test 45) and try to setup
  and clanup the same device twise (from lconf).
