Adding Google Flags-like command-line option parsing, though implemented in C, to the main executable. The code is ported from Granary2.

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.

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.

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.

Make sure to make new lists of messages so that messages from one test don't get put into another.

Changed how the logging works to log to a static buffer, then the hooks pull info out from there.

Got Manticore (with some minor unpublished fixes) working for McTest, based on Yan's initial work. Most of the angr code directly ports over, which is convenient. Haven't yet implemented McTest_Log (which isn't working for angr, curiously).

Made it so that tests can be run on their own, independent of a symbolic executor. This will open up libFuzzer support, and concrete execution of solved-for test case inputs. Removed all stuff related to sections. Made tests get registered via initializers. Working on exposing the API functions to be hooked by Manticore via a special system call with addres 0x41414141. Split the Angr version out into the mctest-angr binary, and going to try to make the mctest binary use Manticore.

Improvements. Now hooking fewer functions, and instead making on big array symbolic. This will make it easier to run the inputs concretely (by eventually filling in the array with the concrete bytes), and will also make possible fuzzer integration (where the fuzzer mutates the bytes of the array) possible.
