When compiling with never compilers vmci causes the following errors
to be reported:
.../vmcrosstalk/common/vmciDs.c: In function "DsHandleMessage":
.../vmcrosstalk/common/vmciDs.c:211: warning: pointer targets in passing
argument 1 of "DsLookupAction" differ in signedness
Fix it by changing name in from int8[] to char[] and making DsHandleMessage
take size_t for "outSize" and "written".
