Week 12: libbdvmi Makefile fix and memory server

[nks5295]

This week, I fixed the build issues that came up when trying to build the libbdvmi with my memory server api.

I also added a hash table and gave the memory server capabilities to serve pages of memory, and keep track of many memory requests.

The latter feature is also tied into the libbdvmi application, rsa_app, such that a page fault will not trigger a memory page to be served.

This upcoming week, I plan on refactoring libbdvmi such that the Driver object is passed through the various classes and each EventHandler object has the Driver in its scope.
I also intend on having detailed research regarding memory paging algorithms and then choosing one.

Future steps will be implementing the memory paging algorithm that I pick.
