Fix "Evaluate 'script' in the global scope"

This fixes commit Evaluate 'script' in the global scope. It caused
Windows builds behave differently than before because path was evaluated twice
and backslashes from Windows' paths got unescaped and effectively wiped out.
Configs could only be passed with "-f ../dir/config.cfg" or "-f
..\\dir\\config.cfg" instead of usual "-f dir/config.cfg" (or using backslash)
as previously.

stm32f1x: use async algorithm in flash programming routine

Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

armv7m: implement async algorithm functions

Split armv7m_run_algorithm into two pieces and use them to reimplement it.
The arch_info parameter is used to keep context between the two calls, so
both calls must refer to the same armv7m_algorithm struct. Ugly but works
for a proof-of-concept.

target: add async algorithm entries to the target type

On supported targets, this may be used to start a long running algorithm in
the background so the target may be interacted with during execution and
later wait for its completion.

The most obvious use case is a double buffered flash algorithm that can
upload the next block of data while the algorithm is flashing the current.

AM/DM37x: add ES1.2 silicon type into account

so let support the revision.

Target events are added to get better gdb support. The run
algorithm functionality are implemented to support feature
fast flash write functionality. The new r/w buffer api is now

kinetis auto mass erase on secured devices

This is a proof of concept to get access to the debug port of a
secured kinetis cpu. On full flash erase the cpu is automatically
secured and the debug port is not accessible.
To get this to work the srst line is needed and the necessary
configuration should be added to the configuration file.

fix enter debug mode for locking

added an alternative way to enter debug mode, which does not require restarting the chip.
this will not always work, but in general it will (failure 0.3%), and failure is not a dramatic issue, simply have to use the full sequence.
the user can only access "halt", which uses the full sequence, so the user should not have any problems.
restarting the chip requires reconfiguring the flash module. the doc is very poor, so i'd rather have the two methods, and live with the 0.3%.

fix irlen handling

sometimes the master tap will be enabled, since tap switching is required during halt/lock/unlocking procedures.
now irscan handles this, avoiding unnecessary warnings and preventing errors.

fix debug mode,lock,unlock

got new info regarding setting the chip to debug mode, and locking/unlocking flash memory.
the newer implementation is a bit slower, but always works.
the previous implementation would randomly (as once every 25k-70k times) get the chip into a state where the freescale tool would be necessary. this is fixed now.

added functions to play around with the jtag state machine. they are not the happiest, but are necessary to be able to execute the halting/locking/unlocking sequences.

fix error handling during halt

the user can execute halt, but no enter_debug_mode. modified the error handling to suite this.
the new implementation of unlocking will use enter_debug_mode, and should not get the same errors as the user would, because not being able to enter debug mode is actually success when checking for locked flash.
