Be stricter about what terminated states are saved as crashes
...
We only want to save a `.crash` file if the input would cause a crash
when executing using the native harness. The old impl treated any state
termination as a crash. Now we add a predicate which checks the `reason`
and decides if the termination represents a crash in the program being
analyzed.
For now, we only flag `InvalidMemoryAccess` exceptions as crashes, as
identified by the `message` property on a `TerminateState` exception.

Fixes one or two subtle issues. But the more interesting fix is that I implemented puts in terms of DeepState_Log. Calls to printf that had no format arguments are transformed by the compiler into calls to puts, but that wasn't being wrapped by DeepState, so it was appearing as though those log messages never actually happened.

Removed usage of old name, added in a Euler power of like primes example. When the pairwise ASSERT_NEs are absent, you get interesting results that show examples of integer overflows.

Adds some error checking around finding important symbols and initializing Manticore/Angr. Adds the ability to save concretized bytes to an output directory. For the time being, I'm going with the approach of the user specifying a output dir, then within that I create directories for each file basename in the tests, and subdirectories for each test name, and in there I put binary test files.

Refactored to split common code between Manticore and Angr out into common.py. Implemented the new deferred streaming stuff, it seems to work semi-well for this simple cases I've tested, but there's still work to do. The latest code has some remaining issues. Printing out the final input bytes in Angr shows the wrong thing, although what gets streamed out is right. This is visible when running mctest-angr examples/ArtihmeticProperties. With Manticore, the big issue is that it doesn't properly pickle smt expressions (or something to this effect), so I'm ending up with multiple definitions of the same stuff and that throws exceptions. This is tricky to deal with because the streaming of output needs to be able to save symbolic data.
