Move libsnark in-repo as a git subtree

This PR pulls in the libsnark subtree at the exact commit that we currently fetch via the depends system. To verify:

```
$ ./contrib/devtools/git-subtree-check.sh src/snark
src/snark in HEAD was last updated to upstream commit 9ada3f84ab484c57b2247c2f41091fd6a0916573 (tree c10a38c759)
src/snark in HEAD currently refers to tree 34e916d3f6
:100644 100644 427f4f4ce9 13e54da68b M	Makefile
:040000 040000 42f29e42d1 dd73536163 M	src
FAIL: subtree directory tree doesn't match subtree commit tree
```

This shows that there are changes relative to what we currently use, due to the later commits in the PR. If we exclude them, we see that the code is identical:

```
$ git checkout 26a8f68ea8
$ ./contrib/devtools/git-subtree-check.sh src/snark
src/snark in HEAD was last updated to upstream commit 9ada3f84ab484c57b2247c2f41091fd6a0916573 (tree c10a38c759)
src/snark in HEAD currently refers to tree c10a38c759
GOOD
```

Closes #820.
