- Boot sector code now reports to freeldr.sys the partition
that it was installed on. This is specified by a byte
value in the boot sector code. By default the boot partition
is set to zero which indicates the active (bootable)
partition, unless the installer sets the value to non-zero.
If FreeLoader is installed on a partition other than
the active (bootable) partition then the installer must
set this byte to that partition number. Otherwise
FreeLoader will not be able to find freeldr.ini.
- i386trap.S: Added debug macros BREAKPOINT(),
INSTRUCTION_BREAKPOINTX(), MEMORY_READWRITE_BREAKPOINTX(), &
MEMORY_WRITE_BREAKPOINTX().
- partition.c (DiskGetPartitionEntry): Add the relative offset
of the extended partition to the partitions start sector.
- ext2.c (Ext2ReadBlockPointerList, Ext2CopyIndirectBlockPointers,
Ext2CopyDoubleIndirectBlockPointers, Ext2CopyTripleIndirectBlockPointers):
Rewrote the block pointer functions so they actually work.
- ini_init.c (IniFileInitialize, IniOpenIniFile): Looks for freeldr.ini
on both the active (bootable) partition and the partition
passed in from the boot sector code.
- meminit.c (MmInitializeMemoryManager, MmFixupSystemMemoryMap,
MmGetEndAddressOfAnyMemory, MmGetAddressablePageCountIncludingHoles,
MmInitPageLookupTable): Fixed bug that would cause FreeLoader to
have an off-by-one error when accessing the last entry in the
page lookup table on systems with 4GB of memory (or memory mapped
at the end of the address space).

- Removed initialization of caching in vfatAttacheFCBToFileObject.
The cache for files is initialized at the first read/write operation.
- Merged vfatExtendSpace and VfatSetAllocationSizeInformation in one function.

CcSetDirtyPinedData. There is no working shutdown function
for writing back each modified cache segment. A reboot or
crash can damage the disk.
- Added CcRosReferenceCache and CcRosDereferenceCache.
- Check at each call to CcRosInitializeFileCache if the cache was
initialized for the file stream by a previous call to this function.
- Check at each call to CcRosReleaseFileCache if this is possible
to delete the caching for the file stream.

for a mapped file (data or image) at the cleanup of a given file object
or force the uninitialization if the last section of a file is deleted.
