- cleaned up str7, str9 and stm32 flash drivers

- str7 flash driver now checks correct busy bits depending on device
- str9 flash driver now disables ITCM order as per st programming manual
- added str7 disable_jtag command
- added gdb_detach command
- updated arm966e cp15 support
- fix crash on mingw build when enabling target_request debugmsgs
