This commit adds test script for testing if any commit has introduced

+DFU TEST CASE DESCRIPTION:
+
+For running test script one needs to create:
+./log and ./bkp
+
+One also need to generate with dd following files:
+
+dat_*
+
+(e.g. dat_127B.img  dat_128B.img  dat_129B.img  dat_33M.img  dat_4095B.img
+dat_4096B.img  dat_4097B.img  dat_63B.img  dat_64B.img  dat_65B.img
+dat_960.img  dat_97M.img)
+
+The size is only important (so if=/dev/urandom), especially corner cases of
+DFU EP0's size of packet (64B). This is very helpful for fixing UDC driver
+regressions.
+
+Moreover on a target device the "dfu_alt_info" env variable should be extended
+to have "dfu_test.bin fat 0 6;" \ entry [1].
+One can use fat, ext4 or any other supported file system.
+
+As a prerequisite one must also create proper partition with file system on it.
+
+Example usage:
+./dfu_gadget_test.sh 11
+
+where 11 is the mumber of alt setting corresponding to entry [1].
