1. GDB will print cryptic error messages if it is not fed keep-alive packets

Browse Source 
within the last 2000ms.

To fix this, add keep_alive() if you are spending >1000ms in an algorithm
thus holding up the server loop.

target_call_timer_callbacks() invokes keep_alive().

2. post_reset script is now executed at normal JTAG speed and not
reset speed.

3. Resume is now synchronous again. Hopefully it will work this time.

/* Code must return to the server loop before 1000ms has returned or invoke

* While it is possible use "set remotetimeout" to more than the default 2000ms
* in GDB, OpenOCD guarantees that it sends keep-alive packages on the
* GDB protocol and it is a bug in OpenOCD not to either return to the server
* loop or invoke keep_alive() every 1000ms.

* This function will send a keep alive packet if >500ms has passed since last time
* it was invoked.
