- Added a "User:" debug level. These are messages that are intended for the user and are part of normal operation.

Browse Source 
- Faster DEBUG/INFO() when they are disabled
- target_read/write_buffer() now uses 16 and 32 bit access for single word aligned requests. Other requests are serviced as quickly as possible.
- *much* faster read/write GDB packets, removing timeout problems.
- GDB read/write packets w/single word aligned 32/16 bit access now use 32/16 bit word access.
- working area can now be changed on the fly. Provides a way to move working area about as MMU is enabled/disabled.
- cleaned up error messages for verify_image.
Thanks Øyvind Harboe
