hfsplus: add HFSX subfolder count support
Adds support for HFSX 'HasFolderCount' flag and a corresponding
'folderCount' field in folder records. (For reference see
HFS_FOLDERCOUNT and kHFSHasFolderCountBit/kHFSHasFolderCountMask in
Apple's source code.)
Ignoring subfolder count leads to fs errors found by Mac:
...
Checking catalog hierarchy.
HasFolderCount flag needs to be set (id = 105)
(It should be 0x10 instead of 0)
Incorrect folder count in a directory (id = 2)
(It should be 7 instead of 6)
...
Steps to reproduce:
Format with "newfs_hfs -s /dev/diskXXX".
Mount in Linux.
Create a new directory in root.
Unmount.
Run "fsck_hfs /dev/diskXXX".
The patch handles directory creation, deletion, and rename.
