[IPHLPAPI]
- Fix a massive memory leak of our entire TDI entity ID database after each call to
getInterfaceInfoSet
- Fix another massive leak of our entire TDI interface table after each call to
getInterfaceInfoByIndex and getInterfaceInfoByName
- Fix some uninitialized variable warnings
- Explorer no longer leaks horrendous amounts of memory (about 1 MB per minute even
without network activity) when the network status icon is in the system tray
