Suppress warnings. Most of this patch was given by keir (thanks!).

Corresponding glog bug: http://code.google.com/p/google-glog/issues/detail?id=10

The differences from keir's patch are:
- For raw_logging.h.in, I just included time.h for struct tm.
- Added a fprintf which warns that we should have died to avoid a warning for unused local variable.
- Added inline for some functions which may be unused in googletest.h.
- Removed DumpPCAndFrameSize as it was unused.
