Summary:
This uses OpenSSL 1.1.0h to build and link against. The `.so`s are
precompiled and hand-patched from [this
repository](https://github.com/passy/android-database-sqlcipher). The
patching was necessary to fix the `SONAME` and corresponding `NEEDED`
flags to *not* contain a `.1.1` version suffix as Gradle will refuse to
bundle those.
We basically only use the headers for the remaining part.
The precompiled version contains ABI support for `arm64-v8a`, `armeabi`,
`armeabi-v7a`, `x86` and most importantly `x86_64`. HOWEVER, `x86_64` is
still excluded for now because folly fails to compile due to a missing
compiler flag:
```
error: needs target feature pclmul
```
This should be easily fixable by ensuring that `-mpclmul` is added to
the CFLAGS if we're compiling for an `x86_64` target in the
`CMakeLists.txt` for Folly.
Closes#113.
