Validate the SYSTEM hive with CmCheckRegistry and purge volatile data with the same function when initializing a hive descriptor for SYSTEM. Also implement SYSTEM recovery code that takes use of SYSTEM log in case something is fishy with the hive. If hive repair doesn't have fully recovered the SYSTEM hive, FreeLdr will load the alternate variant of the SYSTEM hive, aka SYSTEM.ALT. If FreeLdr repairs the hive with a LOG, it will mark it with HBOOT_BOOT_RECOVERED_BY_HIVE_LOG on BootRecover field of the header. All the recovered data that is present as dirty in memory will have to be flushed by the kernel once it is in charge of the system. Otherwise if the system boot occurred by loading SYSTEM.ALT instead, FreeLdr will mark HBOOT_BOOT_RECOVERED_BY_ALTERNATE_HIVE, the kernel will start recovering the main hive as soon as it does any I/O activity into it.
