[CMAKE]

- Specify C4700 (uninitialized variable usage) to cause an error on compile as this is very likely to result in broken code.
[NTDLL]
- Disable ASSERT in LdrpSearchPath that could be reading an uninitialized variable. The routine is not fully implemented so this should likely be re-enabled once it is.
[BROWSEUI]
- Add missing call to BuildRebarBandInfo, or we would end up with an unitialized variable sent to SendMessage.
[PCIX]
- Fix broken ASSERT
- Fix usage of wrong (and uninitialized) variable in the Unicode case for PciGetDescriptionMessage.
[DDK]
- Prepend "_" to local variable of NdisChainBufferAtBack. Fixes code in ndisuio that called this using the same name as the macro's variable (which resulted in NdisChainBufferAtBack assigning the variable to itself).
[WIN32K]
- Fix WinPosShowIconTitle that checked if a variable was NULL before assigning it to anything.
