This will add the BSTAP for the medium and high density devices

This has been tested on STM32F100VE

Currently the board/redbee-*.cfg files incorrectly include the
interface definition.  Move the interfaces to interface/,
and create a single board/redbee.cfg that is common to both boards.
Intended usage is now:
  openocd -f interface/redbee-econotag.cfg -f board/redbee.cfg

buspirate has never supported building on native windows (mingw).
configure will now check this is not the case.

AC_CHECK_FILE will die when cross-compiling. So don't use it to test the existence of guess-rev.sh.

Use "info stacktrace" instead. This fixes build problems with
latest Jim Tcl.

Due to build warnings introduced in newer versions of ftd2xx we
use strings to report errors rather than result codes. This also
gives us the same behaviour as libftdi.

it returned ERROR_OK even though it actually failed.
this made the Tcl interface report success, though it had not succeeded.

i had started my code from dsp5683xx, i renamed a bunch of stuff to names i consider to be better.
i believe no one is using this code, so nobody should be affected. (it's not too late to do this change)

After correcting the reply size counter, it should be safe to rely on it
for the number of bytes expected in the USB read, instead of reading the
endpoint maximum. This doesn't make things go any faster but it's nicer and
removes the local buffer.

Add a helper function for running the queue if it would overflow otherwise.
Use it to simplify the queue fill level checks and optimize in a few cases
that would previously run the queue prematurely.

After the reply_index handling is fixed, there's no need to special case
the out scan.

dtc_queue.reply_index was wrongly being increased during out scans, causing
the queue to be sent before the out buffer was full. This patch increases
raw upload speed by 50% or so.

Function mips_m4k_write_memory() does endianess byte swap,
but this procedure break one byte access (temporary array
overwrites content in buffer).
As a fix, this endianess swap and buffer affecting
is preformed only on hword and word accesses (not on byte access).

Pprogram that loads another program into memory is actually writing the
D- side cache.
The instructions it has loaded can't be executed until they reach the
I-cache.

After the instructions have been written, the loader should arrange to
write back any containing D-cache line and invalidate any locations
already in the I-cache.

For the MIPS Architecture Release2 cores, we can use synci command
that does this job.
For Release1 we must use "cache" instruction.

This patch adds MIPS32 CP0 coprocessor R/W routines,
as well as adequate commands to use these routines via
telnet interface.

Now is becomes possible to affect CP0 internal registers
and configure CPU directly from OpenOCD.

For all architectures we use distinct common magic number,
and this should be a uint32_t type.
Otherwise, comparison with macros will yield compilation
warning.

jtag_execute_queue() is executed as a part of mips_ejtag_drscan_32().
No need for this to be done before - removed for optimisation.
