Use DeepState_CurrentTestRun in take-over test case replays
...
- Map shared memory for `DeepState_CurrentTestRun`
- For non-crashing forked test runs, inspect the above to figure out
what happened. In particular, this supports `CHECK` and soft failures.

Add struct for info about single test runs, update in global setters
...
Instead of exit codes, we will use the global instance of this (shared
with a parent process) to determine the result of forked test runs.

Log all test run result cases in native take-over
...
Warning: this does not work correctly with tests that soft fail, e.g.
via a `CHECK` assertion. This is because the soft failures only update
the child's `DeepState_TestFailed` global variable, but do not exit.
What we will soon do is share memory with the child process, and derive
the "test result" from that shared memeory.

If in take-over mode, exit on fatal error
...
In take-over mode, the "test" is the entire binary being executed as a
child process. So, we want to exit, rather than trying to `longjmp()` to
`DeepState_ReturnToRun`, which was never initialized.

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.

Added prime polynomial example, new Pumping function to address scalability challenges with primality testing, and some improvements to the streaming interface, where if you don't stream in values, then the python side doesn't end up printing out some 'empty' stream infos.

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.

Fixes to stream formatting of doubles, they weren't being streamed before. Implemented the chk versions of printf and such, so that they all route through the logging interface as well. Implemented the concretization APIs.
