Renamed from DEV_MAP_PATH to DEV_MAPPER_PATH. Moved so that the
constant is logically intended for use outside of the DMRaid class.
Also specifically make the string constant have external linkage, rather
than the default internal (static) linkage for constants, so that there
is only one copy of the variable in the program, rather than one copy in
each compilation unit which included DMRaid.h. Namely DMRaid.cc and
GParted_Core.cc.

/* READ THIS!

* This class was created in an effort to reduce the complexity of the
|

* GParted_Core class.
|
|
* This class provides support for motherboard based RAID devices, also know
|
|
* as Fake RAID.
|
|
* Static elements are used in order to reduce the disk accesses required to
|
|
* load the data structures upon each initialization of the class.
