- Enable placing kernel functions in the .INIT section (GCC only, MSVC is TBD). This allows them to be freed from memory after initialization is finished.

- PspMapSystemDll and IopDisplayLoadingMessage are called from non-initialization code, so don't put them in .INIT. CmpHiveRootSecurityDescriptor is called from initialization code, but too late in boot, so don't discard it either.
- Trying to enable this for HAL as well leads to a weird crash very early in boot. Investigation is ongoing. Until then we will just have to keep the huge PCI Class/Vendor tables in memory...
- Enable it for Win32k though as it seems to work fine there.
- Remove INIT_FUNCTION from function prototypes, it serves no purpose there.
See issue 10097 for more details.
