wmkdep: Simplified file scanning for dependencies avoiding too many open files

Browse Source 
This change ensures only one include file is open at a time by storing the
included files on a dynamic list rather than scanning the tree and holding a
list of open buffers.  This new approach is a bit faster and avoids the "too
many open files" error on machines with low limits on the number of file
descriptors allocated to users.
