bug #33114: Segfault after setting the DWEN fuse with Dragon

Browse Source 
* jtagII.c (jtagmkII_getsync): Instead of exit()ing from
deep within the tree when detecting the "need debugWIRE"
situation, properly pass this up as a return code.
* jtagII_private.h (JTAGII_GETSYNC_FAIL_GRACEFUL): New constant.
* stk500v2.c (stk500v2_jtagmkII_open): Don't tell anything
anymore when receiving a JTAGII_GETSYNC_FAIL_GRACEFUL from
jtagmkII_getsync(); silently give up (all necessary has been
said already).
