[Libguestfs] [PATCH v4 1/5] generator: Added tsk_dirent struct
The tsk_dirent struct contains the information gathered via TSK APIs.
The struct contains the following fields:
* tsk_inode: inode of a file
* tsk_type: type of file such as for dirwalk command
* tsk_size: file size in bytes
* tsk_name: path relative to its disk partition
* tsk_flags: bitfield containing extra information

[Libguestfs] [PATCH v4 3/5] New API: internal_filesystem_walk
The internal_filesystem_walk command walks through the FS structures
of a disk partition and returns all the files or directories
which could be found.
The command is able to retrieve information regarding deleted
or unaccessible files where other commands such as stat or find
would fail.
The gathered list of tsk_dirent structs is serialised into XDR format
and written to a file by the appliance.

Library's counterpart of the daemon's internal_filesystem_walk command.
It writes the daemon's command output on a temporary file and parses it,
deserialising the XDR formatted tsk_dirent structs.
It returns to the caller the list of tsk_dirent structs generated by the
internal_filesystem_walk command.

The tests check whether the filesystem_walk command is able to retrieve
information regarding both existing and deleted files.
A NTFS image is used as Ext3+ filesystems deletion is more aggressive
