Updates for the dllchannel. These fix problems with building in mpid/common/locks (the configure there needed to use MPICH_INCLUDE_DIRS) and in the builddll scripts (which needed to properly set that value before invoking the configure in mpid/common/locks). The fix further emphasizes the need to refactor the ch3 code to properly modularize (the locks routines are built several times, with *different* include files. This should be ok because of how those files are used, but it is not robust).
