* Add memory sampling feature.
Currently only gets 10 samples per second, but the overall scaffolding
looks like it works.
Change-Id: I25a2bbcba322f2101c3de598c225f83c902680fa
* Basic memory sample speed-ups.
977 samples/second.
Change-Id: I6ea874f25051aca1cbe3aa2918567a4ee316c4be
* Add base64 dumping of sample buffer.
We can't just dump raw data, because the API we use to get data to the
"user" uses NULL-terminated strings.

* WIP on optimizing PC sampling.
1k samples per second on my laptop, which is roughly double what it was.

* WIP
Change-Id: I4300692355cb0cf997ec59ab5ca71543b295abb0
* Use small batch to sample memory.
5k samples/second. No error checking.

* Collect memory samples near continuously.
Rewrite OpenOCD's core loop to get rid of the fixed 100ms delay.
Now collecting 15k samples/second.

* Support 64-bit address in memory sampling.
* Support sampling 64-bit values.
* Better error reporting. WIP on 64-bit support.
* Speed up single 32-bit memory sample.
21k samples/second.
* WIP on review feedback.
