This includes...
* A minimal vcxproj file to list all the source files required for the build.
Some future Visual Studio user can come along and replace it with a real
actual vcxproj file with all the other metadata that I didn't bother to copy.
* A local.mk file to specify all the custom flags and libraries we need for
the build/link of the TLS plugin.
* Including the project in the list of all FDB sub-projects
* Fixes `make clean` to wipe all of lib/, including libFDBLibTLS.so
And offers a target of `bin/FDBLibTLS.so` that can be built, and I have
verified that it works with simulation.
Note that this requires a build image that contains the previous Dockerfile changes.
For some reason, on some platforms it ends up as a local symbol, even though we
point the linker at the symbol map to expose it. Double-requesting its
exportation makes it appear, though there's possibly a better solution.
