debugfile: replace mixed string/control character notation with hexdump

Browse source 
Example of old notation:

    [10]O[0,0]jartha[0,254,142,131]c[133]hL^{[170][[251,199]+E[181]U+t[247,183,129,165,152]#$[164,22,10,169]r[150,212,3,232,3,0,0,2,0,0,0,8,0]0[8,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,6,9,2,0,0,1,0,217,161,192] D[0,0,0,0,0,0,0]

Example of new notation:

         0:  01 0e 6a 61  72 74 68 61  00 57 00 09  5a 00 42 00  ..jartha.W..Z.B.
        16:  02 01 00 b7  6a d4 20 6f  2b 45 b5                  ....j. o+E.
