  Supress MS warning C4251
  Add a plan to std/filters/test/syncTest.c
  Fix dbUnitTest.c
  avoid void* +=
  Fix and test for macLib losing error status
  update notes
  libCom/test: ipAddrToAsciiTest skip cleanup unless valgrind is possible
  libCom/test: add ipAddrToAsciiTest to testHarness
  db/test: dbPutGetTest check dbGet() of long string field
  db: dbGet() ensure long string nil and actual string length
  db/test: dbPutGetTest check for dbGet() attribute crash
  db: fix dbGet() for attributes as long string
  db/test: dbPutGetTest add test for lp:1678494
  db: fix dbGet() of link fields as DBF_CHAR
