Instead of providing an MBR partition type to InferFileSystem(), make
it call IOCTL_DISK_GET_PARTITION_INFO(_EX) to determine whether the
partition pointed by the path/handle is MBR or GPT. Then, only if it's
MBR, we retrieve its partition type in order to "guess" an adequate file
system name, in case the latter was not recognized already via regular
ways (via GetFileSystemName() / NtQueryVolumeInformationFile()).
- Remove the GetFileSystemNameByHandle() and InferFileSystemByHandle()
functions. Instead, make the other GetFileSystemName*() and
InferFileSystem*() functions accept a HANDLE as an alternative to the
already-existing partition path string. These parameters are exclusive
to each other.
- Rename SetPartitionType() -> SetMBRPartitionType(),
and FileSystemToPartitionType() -> FileSystemToMBRPartitionType()
in order to really clarify what they do (since this code is meant
for MBR partitions only, not GPT ones).
