#99 REENTERANT problem

[Markin Vlad]

sleuthkit-3.0-2009-6-16 on Linux 2.6.29.4

The functions of the library to work with FF (libtsk3) not REENTERANT. They are difficult to use in multithreaded applications.
For example, I need to simultaneously search the files and read the file. Preferably with the use of one object IMG_INFO and FS_INFO.
