Added libalm.so and its dependency liblinprog.so. libalm.so provides a

BLayout implementation (BALMLayout) using the Auckland Layout Model (ALM). The original ALM was implemented by Christof Lutteroth, the Haiku/C++ version by James Kim. The code needs some review, but the test programs seem to work fine. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23889 a95241bf-73f2-0310-859d-f6bbb57e9c96
