Summary: passing of variable argument list reduced, strings sent to logging are now formatted just once - more efficient.
As a result, ugly string malloc+strcpy are not needed anymore.

arm11
--- Added burst memory transfer mode
This does not explicitly query command execution but rather uses a small
delay produced by the FT2232 on certain TAP commands.
A potential failure of this process is detected afterwards and the
program terminates with an error.
'arm11 memwrite burst disable'
can be used to switch this feature off.
'arm11 memwrite error_fatal disable'
can be used to prevent the program to exit on an memory write error
--- Added support for interrupt breaking via VCR register
Use 'arm11 vcr' command to set.
--- Cleaned up the handling of
halt/resume/step/poll, target->state, target->debug_reason,
target_call_event_callbacks() at least as far as I could guess the
intended behaviour from other targets.
Did some overall positive tests with GDB.
--- Added support for breakpoints
Hardware breakpoints only. All breakpoints will be treated as hardware
breakpoints.
All ARM11's seem to have at least 6 hardware breakpoints.
--- Stepping over BKPT added
Modification to PC without touching the target.
--- Stepping over a B or BL to self will do nothing

already in the README or texinfo (and which needs to be updated

fix from Pavel Chromy
this patch fixes an issue in jtag_init - shall not reset jtag to NULL.
This causes jtag interface (USB device) not to be closed properly if jtag chain validation fails.
Once the underlaying jtag interface is initialized, jtag pointer shall be left untouched,
even in case of an error, so that proper cleanup can be done, see exit_handler in openocd.c

- Added TARGET_REQ_DEBUGCHAR target_request debugmsg. This
provides a better impeadance match for debug output char fn's, e.g. eCos.

still adds a line ending
- echo of commands in scripts are now available via debug_level instead of
forced echo
- Added a USER_SAMELINE() for printing without a lineend.

- bugfix in server.c

wasn't necessary in hindsight but anyway.

- "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.
