- "flash write_binary" is now "flash write_bank" to clarify the focus of the 

command and reduce confusion with "flash write_image".
- retired deprecated "flash erase" & "flash write".
- added flash_driver_protect/write/erase() that are wafer thin frontend
 functions to low level driver functions. They implement checks
 that were inconsistently handled by the drivers, e.g. check for
 target halted was done in a spotty fashion.
- use return ERROR_COMMAND_SYNTAX_ERROR to print out
 syntax of command instead of having lots of inlined replicas of
 the command line syntax(some of which were wrong).
- use logging instead of dubious translation of error values to
 human understandable explanations of why things failed.
 The lower levels log the precise reason and the higher
 levels can ammend context as the error propagates up
 the call stack.
- simplified flash API slightly with logging instead of
 allocating and returning information that the caller then
 has to translate into print statements.
